Chapter 5. AMQP Component Available as of Camel version 1.2 The amqp: component supports the AMQP 1.0 protocol using the JMS Client API of the Qpid project. In case you want to use AMQP 0.9 (in particular RabbitMQ) you might also be interested in the Camel RabbitMQ component. Please keep in mind that prior to the Camel 2.17.0 AMQP component supported AMQP 0.9 and above, however since Camel 2.17.0 it supports only AMQP 1.0. Maven users will need to add the following dependency to their pom.xml for this component: <dependency> <groupId>org.apache.camel</groupId> <artifactId>camel-amqp</artifactId> <version>USD{camel.version}</version> <!-- use the same version as your Camel core version --> </dependency> 5.1. URI format amqp:[queue:|topic:]destinationName[?options] 5.2. AMQP Options You can specify all of the various configuration options of the JMS component after the destination name. The AMQP component supports 81 options which are listed below. Name Description Default Type configuration (advanced) To use a shared JMS configuration JmsConfiguration acceptMessagesWhile Stopping (consumer) Specifies whether the consumer accept messages while it is stopping. You may consider enabling this option, if you start and stop JMS routes at runtime, while there are still messages enqueued on the queue. If this option is false, and you stop the JMS route, then messages may be rejected, and the JMS broker would have to attempt redeliveries, which yet again may be rejected, and eventually the message may be moved at a dead letter queue on the JMS broker. To avoid this its recommended to enable this option. false boolean allowReplyManagerQuick Stop (consumer) Whether the DefaultMessageListenerContainer used in the reply managers for request-reply messaging allow the DefaultMessageListenerContainer.runningAllowed flag to quick stop in case JmsConfiguration#isAcceptMessagesWhileStopping is enabled, and org.apache.camel.CamelContext is currently being stopped. This quick stop ability is enabled by default in the regular JMS consumers but to enable for reply managers you must enable this flag. false boolean acknowledgementMode (consumer) The JMS acknowledgement mode defined as an Integer. Allows you to set vendor-specific extensions to the acknowledgment mode.For the regular modes, it is preferable to use the acknowledgementModeName instead. int eagerLoadingOf Properties (consumer) Enables eager loading of JMS properties as soon as a message is loaded which generally is inefficient as the JMS properties may not be required but sometimes can catch early any issues with the underlying JMS provider and the use of JMS properties false boolean acknowledgementModeName (consumer) The JMS acknowledgement name, which is one of: SESSION_TRANSACTED, CLIENT_ACKNOWLEDGE, AUTO_ACKNOWLEDGE, DUPS_OK_ACKNOWLEDGE AUTO_ ACKNOWLEDGE String autoStartup (consumer) Specifies whether the consumer container should auto-startup. true boolean cacheLevel (consumer) Sets the cache level by ID for the underlying JMS resources. See cacheLevelName option for more details. int cacheLevelName (consumer) Sets the cache level by name for the underlying JMS resources. Possible values are: CACHE_AUTO, CACHE_CONNECTION, CACHE_CONSUMER, CACHE_NONE, and CACHE_SESSION. The default setting is CACHE_AUTO. See the Spring documentation and Transactions Cache Levels for more information. CACHE_AUTO String replyToCacheLevelName (producer) Sets the cache level by name for the reply consumer when doing request/reply over JMS. This option only applies when using fixed reply queues (not temporary). Camel will by default use: CACHE_CONSUMER for exclusive or shared w/ replyToSelectorName. And CACHE_SESSION for shared without replyToSelectorName. Some JMS brokers such as IBM WebSphere may require to set the replyToCacheLevelName=CACHE_NONE to work. Note: If using temporary queues then CACHE_NONE is not allowed, and you must use a higher value such as CACHE_CONSUMER or CACHE_SESSION. String clientId (common) Sets the JMS client ID to use. Note that this value, if specified, must be unique and can only be used by a single JMS connection instance. It is typically only required for durable topic subscriptions. If using Apache ActiveMQ you may prefer to use Virtual Topics instead. String concurrentConsumers (consumer) Specifies the default number of concurrent consumers when consuming from JMS (not for request/reply over JMS). See also the maxMessagesPerTask option to control dynamic scaling up/down of threads. When doing request/reply over JMS then the option replyToConcurrentConsumers is used to control number of concurrent consumers on the reply message listener. 1 int replyToConcurrent Consumers (producer) Specifies the default number of concurrent consumers when doing request/reply over JMS. See also the maxMessagesPerTask option to control dynamic scaling up/down of threads. 1 int connectionFactory (common) The connection factory to be use. A connection factory must be configured either on the component or endpoint. ConnectionFactory username (security) Username to use with the ConnectionFactory. You can also configure username/password directly on the ConnectionFactory. String password (security) Password to use with the ConnectionFactory. You can also configure username/password directly on the ConnectionFactory. String deliveryPersistent (producer) Specifies whether persistent delivery is used by default. true boolean deliveryMode (producer) Specifies the delivery mode to be used. Possibles values are those defined by javax.jms.DeliveryMode. NON_PERSISTENT = 1 and PERSISTENT = 2. Integer durableSubscriptionName (common) The durable subscriber name for specifying durable topic subscriptions. The clientId option must be configured as well. String exceptionListener (advanced) Specifies the JMS Exception Listener that is to be notified of any underlying JMS exceptions. ExceptionListener errorHandler (advanced) Specifies a org.springframework.util.ErrorHandler to be invoked in case of any uncaught exceptions thrown while processing a Message. By default these exceptions will be logged at the WARN level, if no errorHandler has been configured. You can configure logging level and whether stack traces should be logged using errorHandlerLoggingLevel and errorHandlerLogStackTrace options. This makes it much easier to configure, than having to code a custom errorHandler. ErrorHandler errorHandlerLogging Level (logging) Allows to configure the default errorHandler logging level for logging uncaught exceptions. WARN LoggingLevel errorHandlerLogStack Trace (logging) Allows to control whether stacktraces should be logged or not, by the default errorHandler. true boolean explicitQosEnabled (producer) Set if the deliveryMode, priority or timeToLive qualities of service should be used when sending messages. This option is based on Spring's JmsTemplate. The deliveryMode, priority and timeToLive options are applied to the current endpoint. This contrasts with the preserveMessageQos option, which operates at message granularity, reading QoS properties exclusively from the Camel In message headers. false boolean exposeListenerSession (consumer) Specifies whether the listener session should be exposed when consuming messages. false boolean idleTaskExecutionLimit (advanced) Specifies the limit for idle executions of a receive task, not having received any message within its execution. If this limit is reached, the task will shut down and leave receiving to other executing tasks (in the case of dynamic scheduling; see the maxConcurrentConsumers setting). There is additional doc available from Spring. 1 int idleConsumerLimit (advanced) Specify the limit for the number of consumers that are allowed to be idle at any given time. 1 int maxConcurrentConsumers (consumer) Specifies the maximum number of concurrent consumers when consuming from JMS (not for request/reply over JMS). See also the maxMessagesPerTask option to control dynamic scaling up/down of threads. When doing request/reply over JMS then the option replyToMaxConcurrentConsumers is used to control number of concurrent consumers on the reply message listener. int replyToMaxConcurrent Consumers (producer) Specifies the maximum number of concurrent consumers when using request/reply over JMS. See also the maxMessagesPerTask option to control dynamic scaling up/down of threads. int replyOnTimeoutToMax ConcurrentConsumers (producer) Specifies the maximum number of concurrent consumers for continue routing when timeout occurred when using request/reply over JMS. 1 int maxMessagesPerTask (advanced) The number of messages per task. -1 is unlimited. If you use a range for concurrent consumers (eg min max), then this option can be used to set a value to eg 100 to control how fast the consumers will shrink when less work is required. -1 int messageConverter (advanced) To use a custom Spring org.springframework.jms.support.converter.MessageConverter so you can be in control how to map to/from a javax.jms.Message. MessageConverter mapJmsMessage (advanced) Specifies whether Camel should auto map the received JMS message to a suited payload type, such as javax.jms.TextMessage to a String etc. true boolean messageIdEnabled (advanced) When sending, specifies whether message IDs should be added. This is just an hint to the JMS broker.If the JMS provider accepts this hint, these messages must have the message ID set to null; if the provider ignores the hint, the message ID must be set to its normal unique value true boolean messageTimestampEnabled (advanced) Specifies whether timestamps should be enabled by default on sending messages. This is just an hint to the JMS broker.If the JMS provider accepts this hint, these messages must have the timestamp set to zero; if the provider ignores the hint the timestamp must be set to its normal value true boolean alwaysCopyMessage (producer) If true, Camel will always make a JMS message copy of the message when it is passed to the producer for sending. Copying the message is needed in some situations, such as when a replyToDestinationSelectorName is set (incidentally, Camel will set the alwaysCopyMessage option to true, if a replyToDestinationSelectorName is set) false boolean useMessageIDAs CorrelationID (advanced) Specifies whether JMSMessageID should always be used as JMSCorrelationID for InOut messages. false boolean priority (producer) Values greater than 1 specify the message priority when sending (where 0 is the lowest priority and 9 is the highest). The explicitQosEnabled option must also be enabled in order for this option to have any effect. 4 int pubSubNoLocal (advanced) Specifies whether to inhibit the delivery of messages published by its own connection. false boolean receiveTimeout (advanced) The timeout for receiving messages (in milliseconds). 1000 long recoveryInterval (advanced) Specifies the interval between recovery attempts, i.e. when a connection is being refreshed, in milliseconds. The default is 5000 ms, that is, 5 seconds. 5000 long taskExecutor (consumer) Allows you to specify a custom task executor for consuming messages. TaskExecutor deliveryDelay (producer) Sets delivery delay to use for send calls for JMS. This option requires JMS 2.0 compliant broker. -1 long timeToLive (producer) When sending messages, specifies the time-to-live of the message (in milliseconds). -1 long transacted (transaction) Specifies whether to use transacted mode false boolean lazyCreateTransaction Manager (transaction) If true, Camel will create a JmsTransactionManager, if there is no transactionManager injected when option transacted=true. true boolean transactionManager (transaction) The Spring transaction manager to use. PlatformTransaction Manager transactionName (transaction) The name of the transaction to use. String transactionTimeout (transaction) The timeout value of the transaction (in seconds), if using transacted mode. -1 int testConnectionOn Startup (common) Specifies whether to test the connection on startup. This ensures that when Camel starts that all the JMS consumers have a valid connection to the JMS broker. If a connection cannot be granted then Camel throws an exception on startup. This ensures that Camel is not started with failed connections. The JMS producers is tested as well. false boolean asyncStartListener (advanced) Whether to startup the JmsConsumer message listener asynchronously, when starting a route. For example if a JmsConsumer cannot get a connection to a remote JMS broker, then it may block while retrying and/or failover. This will cause Camel to block while starting routes. By setting this option to true, you will let routes startup, while the JmsConsumer connects to the JMS broker using a dedicated thread in asynchronous mode. If this option is used, then beware that if the connection could not be established, then an exception is logged at WARN level, and the consumer will not be able to receive messages; You can then restart the route to retry. false boolean asyncStopListener (advanced) Whether to stop the JmsConsumer message listener asynchronously, when stopping a route. false boolean forceSendOriginal Message (producer) When using mapJmsMessage=false Camel will create a new JMS message to send to a new JMS destination if you touch the headers (get or set) during the route. Set this option to true to force Camel to send the original JMS message that was received. false boolean requestTimeout (producer) The timeout for waiting for a reply when using the InOut Exchange Pattern (in milliseconds). The default is 20 seconds. You can include the header CamelJmsRequestTimeout to override this endpoint configured timeout value, and thus have per message individual timeout values. See also the requestTimeoutCheckerInterval option. 20000 long requestTimeoutChecker Interval (advanced) Configures how often Camel should check for timed out Exchanges when doing request/reply over JMS. By default Camel checks once per second. But if you must react faster when a timeout occurs, then you can lower this interval, to check more frequently. The timeout is determined by the option requestTimeout. 1000 long transferExchange (advanced) You can transfer the exchange over the wire instead of just the body and headers. The following fields are transferred: In body, Out body, Fault body, In headers, Out headers, Fault headers, exchange properties, exchange exception. This requires that the objects are serializable. Camel will exclude any non-serializable objects and log it at WARN level. You must enable this option on both the producer and consumer side, so Camel knows the payloads is an Exchange and not a regular payload. false boolean transferException (advanced) If enabled and you are using Request Reply messaging (InOut) and an Exchange failed on the consumer side, then the caused Exception will be send back in response as a javax.jms.ObjectMessage. If the client is Camel, the returned Exception is rethrown. This allows you to use Camel JMS as a bridge in your routing - for example, using persistent queues to enable robust routing. Notice that if you also have transferExchange enabled, this option takes precedence. The caught exception is required to be serializable. The original Exception on the consumer side can be wrapped in an outer exception such as org.apache.camel.RuntimeCamelException when returned to the producer. false boolean transferFault (advanced) If enabled and you are using Request Reply messaging (InOut) and an Exchange failed with a SOAP fault (not exception) on the consumer side, then the fault flag on Message#isFault() will be send back in the response as a JMS header with the key org.apache.camel.component.jms.JmsConstants#JMS_TRANSFER_FAULT#JMS_TRANSFER_FAULT. If the client is Camel, the returned fault flag will be set on the org.apache.camel.Message#setFault(boolean). You may want to enable this when using Camel components that support faults such as SOAP based such as cxf or spring-ws. false boolean jmsOperations (advanced) Allows you to use your own implementation of the org.springframework.jms.core.JmsOperations interface. Camel uses JmsTemplate as default. Can be used for testing purpose, but not used much as stated in the spring API docs. JmsOperations destinationResolver (advanced) A pluggable org.springframework.jms.support.destination.DestinationResolver that allows you to use your own resolver (for example, to lookup the real destination in a JNDI registry). DestinationResolver replyToType (producer) Allows for explicitly specifying which kind of strategy to use for replyTo queues when doing request/reply over JMS. Possible values are: Temporary, Shared, or Exclusive. By default Camel will use temporary queues. However if replyTo has been configured, then Shared is used by default. This option allows you to use exclusive queues instead of shared ones. See Camel JMS documentation for more details, and especially the notes about the implications if running in a clustered environment, and the fact that Shared reply queues has lower performance than its alternatives Temporary and Exclusive. ReplyToType preserveMessageQos (producer) Set to true, if you want to send message using the QoS settings specified on the message, instead of the QoS settings on the JMS endpoint. The following three headers are considered JMSPriority, JMSDeliveryMode, and JMSExpiration. You can provide all or only some of them. If not provided, Camel will fall back to use the values from the endpoint instead. So, when using this option, the headers override the values from the endpoint. The explicitQosEnabled option, by contrast, will only use options set on the endpoint, and not values from the message header. false boolean asyncConsumer (consumer) Whether the JmsConsumer processes the Exchange asynchronously. If enabled then the JmsConsumer may pickup the message from the JMS queue, while the message is being processed asynchronously (by the Asynchronous Routing Engine). This means that messages may be processed not 100% strictly in order. If disabled (as default) then the Exchange is fully processed before the JmsConsumer will pickup the message from the JMS queue. Note if transacted has been enabled, then asyncConsumer=true does not run asynchronously, as transaction must be executed synchronously (Camel 3.0 may support async transactions). false boolean allowNullBody (producer) Whether to allow sending messages with no body. If this option is false and the message body is null, then an JMSException is thrown. true boolean includeSentJMS MessageID (producer) Only applicable when sending to JMS destination using InOnly (eg fire and forget). Enabling this option will enrich the Camel Exchange with the actual JMSMessageID that was used by the JMS client when the message was sent to the JMS destination. false boolean includeAllJMSX Properties (advanced) Whether to include all JMSXxxx properties when mapping from JMS to Camel Message. Setting this to true will include properties such as JMSXAppID, and JMSXUserID etc. Note: If you are using a custom headerFilterStrategy then this option does not apply. false boolean defaultTaskExecutor Type (consumer) Specifies what default TaskExecutor type to use in the DefaultMessageListenerContainer, for both consumer endpoints and the ReplyTo consumer of producer endpoints. Possible values: SimpleAsync (uses Spring's SimpleAsyncTaskExecutor) or ThreadPool (uses Spring's ThreadPoolTaskExecutor with optimal values - cached threadpool-like). If not set, it defaults to the behaviour, which uses a cached thread pool for consumer endpoints and SimpleAsync for reply consumers. The use of ThreadPool is recommended to reduce thread trash in elastic configurations with dynamically increasing and decreasing concurrent consumers. DefaultTaskExecutor Type jmsKeyFormatStrategy (advanced) Pluggable strategy for encoding and decoding JMS keys so they can be compliant with the JMS specification. Camel provides two implementations out of the box: default and passthrough. The default strategy will safely marshal dots and hyphens (. and -). The passthrough strategy leaves the key as is. Can be used for JMS brokers which do not care whether JMS header keys contain illegal characters. You can provide your own implementation of the org.apache.camel.component.jms.JmsKeyFormatStrategy and refer to it using the # notation. JmsKeyFormatStrategy allowAdditionalHeaders (producer) This option is used to allow additional headers which may have values that are invalid according to JMS specification. For example some message systems such as WMQ do this with header names using prefix JMS_IBM_MQMD_ containing values with byte array or other invalid types. You can specify multiple header names separated by comma, and use as suffix for wildcard matching. String queueBrowseStrategy (advanced) To use a custom QueueBrowseStrategy when browsing queues QueueBrowseStrategy messageCreatedStrategy (advanced) To use the given MessageCreatedStrategy which are invoked when Camel creates new instances of javax.jms.Message objects when Camel is sending a JMS message. MessageCreatedStrategy waitForProvision CorrelationToBeUpdated Counter (advanced) Number of times to wait for provisional correlation id to be updated to the actual correlation id when doing request/reply over JMS and when the option useMessageIDAsCorrelationID is enabled. 50 int waitForProvision CorrelationToBeUpdated ThreadSleepingTime (advanced) Interval in millis to sleep each time while waiting for provisional correlation id to be updated. 100 long correlationProperty (producer) Use this JMS property to correlate messages in InOut exchange pattern (request-reply) instead of JMSCorrelationID property. This allows you to exchange messages with systems that do not correlate messages using JMSCorrelationID JMS property. If used JMSCorrelationID will not be used or set by Camel. The value of here named property will be generated if not supplied in the header of the message under the same name. String subscriptionDurable (consumer) Set whether to make the subscription durable. The durable subscription name to be used can be specified through the subscriptionName property. Default is false. Set this to true to register a durable subscription, typically in combination with a subscriptionName value (unless your message listener class name is good enough as subscription name). Only makes sense when listening to a topic (pub-sub domain), therefore this method switches the pubSubDomain flag as well. false boolean subscriptionShared (consumer) Set whether to make the subscription shared. The shared subscription name to be used can be specified through the subscriptionName property. Default is false. Set this to true to register a shared subscription, typically in combination with a subscriptionName value (unless your message listener class name is good enough as subscription name). Note that shared subscriptions may also be durable, so this flag can (and often will) be combined with subscriptionDurable as well. Only makes sense when listening to a topic (pub-sub domain), therefore this method switches the pubSubDomain flag as well. Requires a JMS 2.0 compatible message broker. false boolean subscriptionName (consumer) Set the name of a subscription to create. To be applied in case of a topic (pub-sub domain) with a shared or durable subscription. The subscription name needs to be unique within this client's JMS client id. Default is the class name of the specified message listener. Note: Only 1 concurrent consumer (which is the default of this message listener container) is allowed for each subscription, except for a shared subscription (which requires JMS 2.0). String streamMessageType Enabled (producer) Sets whether StreamMessage type is enabled or not. Message payloads of streaming kind such as files, InputStream, etc will either by sent as BytesMessage or StreamMessage. This option controls which kind will be used. By default BytesMessage is used which enforces the entire message payload to be read into memory. By enabling this option the message payload is read into memory in chunks and each chunk is then written to the StreamMessage until no more data. false boolean formatDateHeadersTo Iso8601 (producer) Sets whether date headers should be formatted according to the ISO 8601 standard. false boolean headerFilterStrategy (filter) To use a custom org.apache.camel.spi.HeaderFilterStrategy to filter header to and from Camel message. HeaderFilterStrategy resolveProperty Placeholders (advanced) Whether the component should resolve property placeholders on itself when starting. Only properties which are of String type can use property placeholders. true boolean The AMQP endpoint is configured using URI syntax: with the following path and query parameters: 5.2.1. Path Parameters (2 parameters): Name Description Default Type destinationType The kind of destination to use queue String destinationName Required Name of the queue or topic to use as destination String 5.2.2. Query Parameters (92 parameters): Name Description Default Type clientId (common) Sets the JMS client ID to use. Note that this value, if specified, must be unique and can only be used by a single JMS connection instance. It is typically only required for durable topic subscriptions. If using Apache ActiveMQ you may prefer to use Virtual Topics instead. String connectionFactory (common) The connection factory to be use. A connection factory must be configured either on the component or endpoint. ConnectionFactory disableReplyTo (common) Specifies whether Camel ignores the JMSReplyTo header in messages. If true, Camel does not send a reply back to the destination specified in the JMSReplyTo header. You can use this option if you want Camel to consume from a route and you do not want Camel to automatically send back a reply message because another component in your code handles the reply message. You can also use this option if you want to use Camel as a proxy between different message brokers and you want to route message from one system to another. false boolean durableSubscriptionName (common) The durable subscriber name for specifying durable topic subscriptions. The clientId option must be configured as well. String jmsMessageType (common) Allows you to force the use of a specific javax.jms.Message implementation for sending JMS messages. Possible values are: Bytes, Map, Object, Stream, Text. By default, Camel would determine which JMS message type to use from the In body type. This option allows you to specify it. JmsMessageType testConnectionOnStartup (common) Specifies whether to test the connection on startup. This ensures that when Camel starts that all the JMS consumers have a valid connection to the JMS broker. If a connection cannot be granted then Camel throws an exception on startup. This ensures that Camel is not started with failed connections. The JMS producers is tested as well. false boolean acknowledgementModeName (consumer) The JMS acknowledgement name, which is one of: SESSION_TRANSACTED, CLIENT_ACKNOWLEDGE, AUTO_ACKNOWLEDGE, DUPS_OK_ACKNOWLEDGE AUTO_ ACKNOWLEDGE String asyncConsumer (consumer) Whether the JmsConsumer processes the Exchange asynchronously. If enabled then the JmsConsumer may pickup the message from the JMS queue, while the message is being processed asynchronously (by the Asynchronous Routing Engine). This means that messages may be processed not 100% strictly in order. If disabled (as default) then the Exchange is fully processed before the JmsConsumer will pickup the message from the JMS queue. Note if transacted has been enabled, then asyncConsumer=true does not run asynchronously, as transaction must be executed synchronously (Camel 3.0 may support async transactions). false boolean autoStartup (consumer) Specifies whether the consumer container should auto-startup. true boolean bridgeErrorHandler (consumer) Allows for bridging the consumer to the Camel routing Error Handler, which mean any exceptions occurred while the consumer is trying to pickup incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler. By default the consumer will use the org.apache.camel.spi.ExceptionHandler to deal with exceptions, that will be logged at WARN or ERROR level and ignored. false boolean cacheLevel (consumer) Sets the cache level by ID for the underlying JMS resources. See cacheLevelName option for more details. int cacheLevelName (consumer) Sets the cache level by name for the underlying JMS resources. Possible values are: CACHE_AUTO, CACHE_CONNECTION, CACHE_CONSUMER, CACHE_NONE, and CACHE_SESSION. The default setting is CACHE_AUTO. See the Spring documentation and Transactions Cache Levels for more information. CACHE_AUTO String concurrentConsumers (consumer) Specifies the default number of concurrent consumers when consuming from JMS (not for request/reply over JMS). See also the maxMessagesPerTask option to control dynamic scaling up/down of threads. When doing request/reply over JMS then the option replyToConcurrentConsumers is used to control number of concurrent consumers on the reply message listener. 1 int maxConcurrentConsumers (consumer) Specifies the maximum number of concurrent consumers when consuming from JMS (not for request/reply over JMS). See also the maxMessagesPerTask option to control dynamic scaling up/down of threads. When doing request/reply over JMS then the option replyToMaxConcurrentConsumers is used to control number of concurrent consumers on the reply message listener. int replyTo (consumer) Provides an explicit ReplyTo destination, which overrides any incoming value of Message.getJMSReplyTo(). String replyToDeliveryPersistent (consumer) Specifies whether to use persistent delivery by default for replies. true boolean selector (consumer) Sets the JMS selector to use String subscriptionDurable (consumer) Set whether to make the subscription durable. The durable subscription name to be used can be specified through the subscriptionName property. Default is false. Set this to true to register a durable subscription, typically in combination with a subscriptionName value (unless your message listener class name is good enough as subscription name). Only makes sense when listening to a topic (pub-sub domain), therefore this method switches the pubSubDomain flag as well. false boolean subscriptionName (consumer) Set the name of a subscription to create. To be applied in case of a topic (pub-sub domain) with a shared or durable subscription. The subscription name needs to be unique within this client's JMS client id. Default is the class name of the specified message listener. Note: Only 1 concurrent consumer (which is the default of this message listener container) is allowed for each subscription, except for a shared subscription (which requires JMS 2.0). String subscriptionShared (consumer) Set whether to make the subscription shared. The shared subscription name to be used can be specified through the subscriptionName property. Default is false. Set this to true to register a shared subscription, typically in combination with a subscriptionName value (unless your message listener class name is good enough as subscription name). Note that shared subscriptions may also be durable, so this flag can (and often will) be combined with subscriptionDurable as well. Only makes sense when listening to a topic (pub-sub domain), therefore this method switches the pubSubDomain flag as well. Requires a JMS 2.0 compatible message broker. false boolean acceptMessagesWhileStopping (consumer) Specifies whether the consumer accept messages while it is stopping. You may consider enabling this option, if you start and stop JMS routes at runtime, while there are still messages enqueued on the queue. If this option is false, and you stop the JMS route, then messages may be rejected, and the JMS broker would have to attempt redeliveries, which yet again may be rejected, and eventually the message may be moved at a dead letter queue on the JMS broker. To avoid this its recommended to enable this option. false boolean allowReplyManagerQuickStop (consumer) Whether the DefaultMessageListenerContainer used in the reply managers for request-reply messaging allow the DefaultMessageListenerContainer.runningAllowed flag to quick stop in case JmsConfiguration#isAcceptMessagesWhileStopping is enabled, and org.apache.camel.CamelContext is currently being stopped. This quick stop ability is enabled by default in the regular JMS consumers but to enable for reply managers you must enable this flag. false boolean consumerType (consumer) The consumer type to use, which can be one of: Simple, Default, or Custom. The consumer type determines which Spring JMS listener to use. Default will use org.springframework.jms.listener.DefaultMessageListenerContainer, Simple will use org.springframework.jms.listener.SimpleMessageListenerContainer. When Custom is specified, the MessageListenerContainerFactory defined by the messageListenerContainerFactory option will determine what org.springframework.jms.listener.AbstractMessageListenerContainer to use. Default ConsumerType defaultTaskExecutorType (consumer) Specifies what default TaskExecutor type to use in the DefaultMessageListenerContainer, for both consumer endpoints and the ReplyTo consumer of producer endpoints. Possible values: SimpleAsync (uses Spring's SimpleAsyncTaskExecutor) or ThreadPool (uses Spring's ThreadPoolTaskExecutor with optimal values - cached threadpool-like). If not set, it defaults to the behaviour, which uses a cached thread pool for consumer endpoints and SimpleAsync for reply consumers. The use of ThreadPool is recommended to reduce thread trash in elastic configurations with dynamically increasing and decreasing concurrent consumers. DefaultTaskExecutor Type eagerLoadingOfProperties (consumer) Enables eager loading of JMS properties and payload as soon as a message is loaded which generally is inefficient as the JMS properties may not be required but sometimes can catch early any issues with the underlying JMS provider and the use of JMS properties false boolean exceptionHandler (consumer) To let the consumer use a custom ExceptionHandler. Notice if the option bridgeErrorHandler is enabled then this option is not in use. By default the consumer will deal with exceptions, that will be logged at WARN or ERROR level and ignored. ExceptionHandler exchangePattern (consumer) Sets the exchange pattern when the consumer creates an exchange. ExchangePattern exposeListenerSession (consumer) Specifies whether the listener session should be exposed when consuming messages. false boolean replyToSameDestination Allowed (consumer) Whether a JMS consumer is allowed to send a reply message to the same destination that the consumer is using to consume from. This prevents an endless loop by consuming and sending back the same message to itself. false boolean taskExecutor (consumer) Allows you to specify a custom task executor for consuming messages. TaskExecutor deliveryDelay (producer) Sets delivery delay to use for send calls for JMS. This option requires JMS 2.0 compliant broker. -1 long deliveryMode (producer) Specifies the delivery mode to be used. Possibles values are those defined by javax.jms.DeliveryMode. NON_PERSISTENT = 1 and PERSISTENT = 2. Integer deliveryPersistent (producer) Specifies whether persistent delivery is used by default. true boolean explicitQosEnabled (producer) Set if the deliveryMode, priority or timeToLive qualities of service should be used when sending messages. This option is based on Spring's JmsTemplate. The deliveryMode, priority and timeToLive options are applied to the current endpoint. This contrasts with the preserveMessageQos option, which operates at message granularity, reading QoS properties exclusively from the Camel In message headers. false Boolean formatDateHeadersToIso8601 (producer) Sets whether JMS date properties should be formatted according to the ISO 8601 standard. false boolean preserveMessageQos (producer) Set to true, if you want to send message using the QoS settings specified on the message, instead of the QoS settings on the JMS endpoint. The following three headers are considered JMSPriority, JMSDeliveryMode, and JMSExpiration. You can provide all or only some of them. If not provided, Camel will fall back to use the values from the endpoint instead. So, when using this option, the headers override the values from the endpoint. The explicitQosEnabled option, by contrast, will only use options set on the endpoint, and not values from the message header. false boolean priority (producer) Values greater than 1 specify the message priority when sending (where 0 is the lowest priority and 9 is the highest). The explicitQosEnabled option must also be enabled in order for this option to have any effect. 4 int replyToConcurrentConsumers (producer) Specifies the default number of concurrent consumers when doing request/reply over JMS. See also the maxMessagesPerTask option to control dynamic scaling up/down of threads. 1 int replyToMaxConcurrent Consumers (producer) Specifies the maximum number of concurrent consumers when using request/reply over JMS. See also the maxMessagesPerTask option to control dynamic scaling up/down of threads. int replyToOnTimeoutMax ConcurrentConsumers (producer) Specifies the maximum number of concurrent consumers for continue routing when timeout occurred when using request/reply over JMS. 1 int replyToOverride (producer) Provides an explicit ReplyTo destination in the JMS message, which overrides the setting of replyTo. It is useful if you want to forward the message to a remote Queue and receive the reply message from the ReplyTo destination. String replyToType (producer) Allows for explicitly specifying which kind of strategy to use for replyTo queues when doing request/reply over JMS. Possible values are: Temporary, Shared, or Exclusive. By default Camel will use temporary queues. However if replyTo has been configured, then Shared is used by default. This option allows you to use exclusive queues instead of shared ones. See Camel JMS documentation for more details, and especially the notes about the implications if running in a clustered environment, and the fact that Shared reply queues has lower performance than its alternatives Temporary and Exclusive. ReplyToType requestTimeout (producer) The timeout for waiting for a reply when using the InOut Exchange Pattern (in milliseconds). The default is 20 seconds. You can include the header CamelJmsRequestTimeout to override this endpoint configured timeout value, and thus have per message individual timeout values. See also the requestTimeoutCheckerInterval option. 20000 long timeToLive (producer) When sending messages, specifies the time-to-live of the message (in milliseconds). -1 long allowAdditionalHeaders (producer) This option is used to allow additional headers which may have values that are invalid according to JMS specification. For example some message systems such as WMQ do this with header names using prefix JMS_IBM_MQMD_ containing values with byte array or other invalid types. You can specify multiple header names separated by comma, and use as suffix for wildcard matching. String allowNullBody (producer) Whether to allow sending messages with no body. If this option is false and the message body is null, then an JMSException is thrown. true boolean alwaysCopyMessage (producer) If true, Camel will always make a JMS message copy of the message when it is passed to the producer for sending. Copying the message is needed in some situations, such as when a replyToDestinationSelectorName is set (incidentally, Camel will set the alwaysCopyMessage option to true, if a replyToDestinationSelectorName is set) false boolean correlationProperty (producer) When using InOut exchange pattern use this JMS property instead of JMSCorrelationID JMS property to correlate messages. If set messages will be correlated solely on the value of this property JMSCorrelationID property will be ignored and not set by Camel. String disableTimeToLive (producer) Use this option to force disabling time to live. For example when you do request/reply over JMS, then Camel will by default use the requestTimeout value as time to live on the message being sent. The problem is that the sender and receiver systems have to have their clocks synchronized, so they are in sync. This is not always so easy to archive. So you can use disableTimeToLive=true to not set a time to live value on the sent message. Then the message will not expire on the receiver system. See below in section About time to live for more details. false boolean forceSendOriginalMessage (producer) When using mapJmsMessage=false Camel will create a new JMS message to send to a new JMS destination if you touch the headers (get or set) during the route. Set this option to true to force Camel to send the original JMS message that was received. false boolean includeSentJMSMessageID (producer) Only applicable when sending to JMS destination using InOnly (eg fire and forget). Enabling this option will enrich the Camel Exchange with the actual JMSMessageID that was used by the JMS client when the message was sent to the JMS destination. false boolean replyToCacheLevelName (producer) Sets the cache level by name for the reply consumer when doing request/reply over JMS. This option only applies when using fixed reply queues (not temporary). Camel will by default use: CACHE_CONSUMER for exclusive or shared w/ replyToSelectorName. And CACHE_SESSION for shared without replyToSelectorName. Some JMS brokers such as IBM WebSphere may require to set the replyToCacheLevelName=CACHE_NONE to work. Note: If using temporary queues then CACHE_NONE is not allowed, and you must use a higher value such as CACHE_CONSUMER or CACHE_SESSION. String replyToDestinationSelector Name (producer) Sets the JMS Selector using the fixed name to be used so you can filter out your own replies from the others when using a shared queue (that is, if you are not using a temporary reply queue). String streamMessageTypeEnabled (producer) Sets whether StreamMessage type is enabled or not. Message payloads of streaming kind such as files, InputStream, etc will either by sent as BytesMessage or StreamMessage. This option controls which kind will be used. By default BytesMessage is used which enforces the entire message payload to be read into memory. By enabling this option the message payload is read into memory in chunks and each chunk is then written to the StreamMessage until no more data. false boolean allowSerializedHeaders (advanced) Controls whether or not to include serialized headers. Applies only when transferExchange is true. This requires that the objects are serializable. Camel will exclude any non-serializable objects and log it at WARN level. false boolean asyncStartListener (advanced) Whether to startup the JmsConsumer message listener asynchronously, when starting a route. For example if a JmsConsumer cannot get a connection to a remote JMS broker, then it may block while retrying and/or failover. This will cause Camel to block while starting routes. By setting this option to true, you will let routes startup, while the JmsConsumer connects to the JMS broker using a dedicated thread in asynchronous mode. If this option is used, then beware that if the connection could not be established, then an exception is logged at WARN level, and the consumer will not be able to receive messages; You can then restart the route to retry. false boolean asyncStopListener (advanced) Whether to stop the JmsConsumer message listener asynchronously, when stopping a route. false boolean destinationResolver (advanced) A pluggable org.springframework.jms.support.destination.DestinationResolver that allows you to use your own resolver (for example, to lookup the real destination in a JNDI registry). DestinationResolver errorHandler (advanced) Specifies a org.springframework.util.ErrorHandler to be invoked in case of any uncaught exceptions thrown while processing a Message. By default these exceptions will be logged at the WARN level, if no errorHandler has been configured. You can configure logging level and whether stack traces should be logged using errorHandlerLoggingLevel and errorHandlerLogStackTrace options. This makes it much easier to configure, than having to code a custom errorHandler. ErrorHandler exceptionListener (advanced) Specifies the JMS Exception Listener that is to be notified of any underlying JMS exceptions. ExceptionListener headerFilterStrategy (advanced) To use a custom HeaderFilterStrategy to filter header to and from Camel message. HeaderFilterStrategy idleConsumerLimit (advanced) Specify the limit for the number of consumers that are allowed to be idle at any given time. 1 int idleTaskExecutionLimit (advanced) Specifies the limit for idle executions of a receive task, not having received any message within its execution. If this limit is reached, the task will shut down and leave receiving to other executing tasks (in the case of dynamic scheduling; see the maxConcurrentConsumers setting). There is additional doc available from Spring. 1 int includeAllJMSXProperties (advanced) Whether to include all JMSXxxx properties when mapping from JMS to Camel Message. Setting this to true will include properties such as JMSXAppID, and JMSXUserID etc. Note: If you are using a custom headerFilterStrategy then this option does not apply. false boolean jmsKeyFormatStrategy (advanced) Pluggable strategy for encoding and decoding JMS keys so they can be compliant with the JMS specification. Camel provides two implementations out of the box: default and passthrough. The default strategy will safely marshal dots and hyphens (. and -). The passthrough strategy leaves the key as is. Can be used for JMS brokers which do not care whether JMS header keys contain illegal characters. You can provide your own implementation of the org.apache.camel.component.jms.JmsKeyFormatStrategy and refer to it using the # notation. String mapJmsMessage (advanced) Specifies whether Camel should auto map the received JMS message to a suited payload type, such as javax.jms.TextMessage to a String etc. true boolean maxMessagesPerTask (advanced) The number of messages per task. -1 is unlimited. If you use a range for concurrent consumers (eg min max), then this option can be used to set a value to eg 100 to control how fast the consumers will shrink when less work is required. -1 int messageConverter (advanced) To use a custom Spring org.springframework.jms.support.converter.MessageConverter so you can be in control how to map to/from a javax.jms.Message. MessageConverter messageCreatedStrategy (advanced) To use the given MessageCreatedStrategy which are invoked when Camel creates new instances of javax.jms.Message objects when Camel is sending a JMS message. MessageCreatedStrategy messageIdEnabled (advanced) When sending, specifies whether message IDs should be added. This is just an hint to the JMS broker.If the JMS provider accepts this hint, these messages must have the message ID set to null; if the provider ignores the hint, the message ID must be set to its normal unique value true boolean messageListenerContainer Factory (advanced) Registry ID of the MessageListenerContainerFactory used to determine what org.springframework.jms.listener.AbstractMessageListenerContainer to use to consume messages. Setting this will automatically set consumerType to Custom. MessageListener ContainerFactory messageTimestampEnabled (advanced) Specifies whether timestamps should be enabled by default on sending messages. This is just an hint to the JMS broker.If the JMS provider accepts this hint, these messages must have the timestamp set to zero; if the provider ignores the hint the timestamp must be set to its normal value true boolean pubSubNoLocal (advanced) Specifies whether to inhibit the delivery of messages published by its own connection. false boolean receiveTimeout (advanced) The timeout for receiving messages (in milliseconds). 1000 long recoveryInterval (advanced) Specifies the interval between recovery attempts, i.e. when a connection is being refreshed, in milliseconds. The default is 5000 ms, that is, 5 seconds. 5000 long requestTimeoutChecker Interval (advanced) Configures how often Camel should check for timed out Exchanges when doing request/reply over JMS. By default Camel checks once per second. But if you must react faster when a timeout occurs, then you can lower this interval, to check more frequently. The timeout is determined by the option requestTimeout. 1000 long synchronous (advanced) Sets whether synchronous processing should be strictly used, or Camel is allowed to use asynchronous processing (if supported). false boolean transferException (advanced) If enabled and you are using Request Reply messaging (InOut) and an Exchange failed on the consumer side, then the caused Exception will be send back in response as a javax.jms.ObjectMessage. If the client is Camel, the returned Exception is rethrown. This allows you to use Camel JMS as a bridge in your routing - for example, using persistent queues to enable robust routing. Notice that if you also have transferExchange enabled, this option takes precedence. The caught exception is required to be serializable. The original Exception on the consumer side can be wrapped in an outer exception such as org.apache.camel.RuntimeCamelException when returned to the producer. false boolean transferExchange (advanced) You can transfer the exchange over the wire instead of just the body and headers. The following fields are transferred: In body, Out body, Fault body, In headers, Out headers, Fault headers, exchange properties, exchange exception. This requires that the objects are serializable. Camel will exclude any non-serializable objects and log it at WARN level. You must enable this option on both the producer and consumer side, so Camel knows the payloads is an Exchange and not a regular payload. false boolean transferFault (advanced) If enabled and you are using Request Reply messaging (InOut) and an Exchange failed with a SOAP fault (not exception) on the consumer side, then the fault flag on Message#isFault() will be send back in the response as a JMS header with the key org.apache.camel.component.jms.JmsConstants#JMS_TRANSFER_FAULT#JMS_TRANSFER_FAULT. If the client is Camel, the returned fault flag will be set on the org.apache.camel.Message#setFault(boolean). You may want to enable this when using Camel components that support faults such as SOAP based such as cxf or spring-ws. false boolean useMessageIDAsCorrelation ID (advanced) Specifies whether JMSMessageID should always be used as JMSCorrelationID for InOut messages. false boolean waitForProvisionCorrelation ToBeUpdatedCounter (advanced) Number of times to wait for provisional correlation id to be updated to the actual correlation id when doing request/reply over JMS and when the option useMessageIDAsCorrelationID is enabled. 50 int waitForProvisionCorrelation ToBeUpdatedThreadSleeping Time (advanced) Interval in millis to sleep each time while waiting for provisional correlation id to be updated. 100 long errorHandlerLoggingLevel (logging) Allows to configure the default errorHandler logging level for logging uncaught exceptions. WARN LoggingLevel errorHandlerLogStackTrace (logging) Allows to control whether stacktraces should be logged or not, by the default errorHandler. true boolean password (security) Password to use with the ConnectionFactory. You can also configure username/password directly on the ConnectionFactory. String username (security) Username to use with the ConnectionFactory. You can also configure username/password directly on the ConnectionFactory. String transacted (transaction) Specifies whether to use transacted mode false boolean lazyCreateTransaction Manager (transaction) If true, Camel will create a JmsTransactionManager, if there is no transactionManager injected when option transacted=true. true boolean transactionManager (transaction) The Spring transaction manager to use. PlatformTransaction Manager transactionName (transaction) The name of the transaction to use. String transactionTimeout (transaction) The timeout value of the transaction (in seconds), if using transacted mode. -1 int 5.3. Spring Boot Auto-Configuration The component supports 81 options, which are listed below. Name Description Default Type camel.component.amqp.accept-messages-while-stopping Specifies whether the consumer accept messages while it is stopping. You may consider enabling this option, if you start and stop JMS routes at runtime, while there are still messages enqueued on the queue. If this option is false, and you stop the JMS route, then messages may be rejected, and the JMS broker would have to attempt redeliveries, which yet again may be rejected, and eventually the message may be moved at a dead letter queue on the JMS broker. To avoid this its recommended to enable this option. false Boolean camel.component.amqp.acknowledgement-mode The JMS acknowledgement mode defined as an Integer. Allows you to set vendor-specific extensions to the acknowledgment mode.For the regular modes, it is preferable to use the acknowledgementModeName instead. Integer camel.component.amqp.acknowledgement-mode-name The JMS acknowledgement name, which is one of: SESSION_TRANSACTED, CLIENT_ACKNOWLEDGE, AUTO_ACKNOWLEDGE, DUPS_OK_ACKNOWLEDGE AUTO_ ACKNOWLEDGE String camel.component.amqp.allow-additional-headers This option is used to allow additional headers which may have values that are invalid according to JMS specification. For example some message systems such as WMQ do this with header names using prefix JMS_IBM_MQMD_ containing values with byte array or other invalid types. You can specify multiple header names separated by comma, and use as suffix for wildcard matching. String camel.component.amqp.allow-null-body Whether to allow sending messages with no body. If this option is false and the message body is null, then an JMSException is thrown. true Boolean camel.component.amqp.allow-reply-manager-quick-stop Whether the DefaultMessageListenerContainer used in the reply managers for request-reply messaging allow the DefaultMessageListenerContainer.runningAllowed flag to quick stop in case JmsConfiguration#isAcceptMessagesWhileStopping is enabled, and org.apache.camel.CamelContext is currently being stopped. This quick stop ability is enabled by default in the regular JMS consumers but to enable for reply managers you must enable this flag. false Boolean camel.component.amqp.always-copy-message If true, Camel will always make a JMS message copy of the message when it is passed to the producer for sending. Copying the message is needed in some situations, such as when a replyToDestinationSelectorName is set (incidentally, Camel will set the alwaysCopyMessage option to true, if a replyToDestinationSelectorName is set) false Boolean camel.component.amqp.async-consumer Whether the JmsConsumer processes the Exchange asynchronously. If enabled then the JmsConsumer may pickup the message from the JMS queue, while the message is being processed asynchronously (by the Asynchronous Routing Engine). This means that messages may be processed not 100% strictly in order. If disabled (as default) then the Exchange is fully processed before the JmsConsumer will pickup the message from the JMS queue. Note if transacted has been enabled, then asyncConsumer=true does not run asynchronously, as transaction must be executed synchronously (Camel 3.0 may support async transactions). false Boolean camel.component.amqp.async-start-listener Whether to startup the JmsConsumer message listener asynchronously, when starting a route. For example if a JmsConsumer cannot get a connection to a remote JMS broker, then it may block while retrying and/or failover. This will cause Camel to block while starting routes. By setting this option to true, you will let routes startup, while the JmsConsumer connects to the JMS broker using a dedicated thread in asynchronous mode. If this option is used, then beware that if the connection could not be established, then an exception is logged at WARN level, and the consumer will not be able to receive messages; You can then restart the route to retry. false Boolean camel.component.amqp.async-stop-listener Whether to stop the JmsConsumer message listener asynchronously, when stopping a route. false Boolean camel.component.amqp.auto-startup Specifies whether the consumer container should auto-startup. true Boolean camel.component.amqp.cache-level Sets the cache level by ID for the underlying JMS resources. See cacheLevelName option for more details. Integer camel.component.amqp.cache-level-name Sets the cache level by name for the underlying JMS resources. Possible values are: CACHE_AUTO, CACHE_CONNECTION, CACHE_CONSUMER, CACHE_NONE, and CACHE_SESSION. The default setting is CACHE_AUTO. See the Spring documentation and Transactions Cache Levels for more information. CACHE_AUTO String camel.component.amqp.client-id Sets the JMS client ID to use. Note that this value, if specified, must be unique and can only be used by a single JMS connection instance. It is typically only required for durable topic subscriptions. If using Apache ActiveMQ you may prefer to use Virtual Topics instead. String camel.component.amqp.concurrent-consumers Specifies the default number of concurrent consumers when consuming from JMS (not for request/reply over JMS). See also the maxMessagesPerTask option to control dynamic scaling up/down of threads. When doing request/reply over JMS then the option replyToConcurrentConsumers is used to control number of concurrent consumers on the reply message listener. 1 Integer camel.component.amqp.configuration To use a shared JMS configuration. The option is a org.apache.camel.component.jms.JmsConfiguration type. String camel.component.amqp.connection-factory The connection factory to be use. A connection factory must be configured either on the component or endpoint. The option is a javax.jms.ConnectionFactory type. String camel.component.amqp.correlation-property Use this JMS property to correlate messages in InOut exchange pattern (request-reply) instead of JMSCorrelationID property. This allows you to exchange messages with systems that do not correlate messages using JMSCorrelationID JMS property. If used JMSCorrelationID will not be used or set by Camel. The value of here named property will be generated if not supplied in the header of the message under the same name. String camel.component.amqp.default-task-executor-type Specifies what default TaskExecutor type to use in the DefaultMessageListenerContainer, for both consumer endpoints and the ReplyTo consumer of producer endpoints. Possible values: SimpleAsync (uses Spring's SimpleAsyncTaskExecutor) or ThreadPool (uses Spring's ThreadPoolTaskExecutor with optimal values - cached threadpool-like). If not set, it defaults to the behaviour, which uses a cached thread pool for consumer endpoints and SimpleAsync for reply consumers. The use of ThreadPool is recommended to reduce thread trash in elastic configurations with dynamically increasing and decreasing concurrent consumers. DefaultTaskExecutor Type camel.component.amqp.delivery-mode Specifies the delivery mode to be used. Possibles values are those defined by javax.jms.DeliveryMode. NON_PERSISTENT = 1 and PERSISTENT = 2. Integer camel.component.amqp.delivery-persistent Specifies whether persistent delivery is used by default. true Boolean camel.component.amqp.destination-resolver A pluggable org.springframework.jms.support.destination.DestinationResolver that allows you to use your own resolver (for example, to lookup the real destination in a JNDI registry). The option is a org.springframework.jms.support.destination.DestinationResolver type. String camel.component.amqp.durable-subscription-name The durable subscriber name for specifying durable topic subscriptions. The clientId option must be configured as well. String camel.component.amqp.eager-loading-of-properties Enables eager loading of JMS properties as soon as a message is loaded which generally is inefficient as the JMS properties may not be required but sometimes can catch early any issues with the underlying JMS provider and the use of JMS properties false Boolean camel.component.amqp.enabled Enable amqp component true Boolean camel.component.amqp.error-handler Specifies a org.springframework.util.ErrorHandler to be invoked in case of any uncaught exceptions thrown while processing a Message. By default these exceptions will be logged at the WARN level, if no errorHandler has been configured. You can configure logging level and whether stack traces should be logged using errorHandlerLoggingLevel and errorHandlerLogStackTrace options. This makes it much easier to configure, than having to code a custom errorHandler. The option is a org.springframework.util.ErrorHandler type. String camel.component.amqp.error-handler-log-stack-trace Allows to control whether stacktraces should be logged or not, by the default errorHandler. true Boolean camel.component.amqp.error-handler-logging-level Allows to configure the default errorHandler logging level for logging uncaught exceptions. LoggingLevel camel.component.amqp.exception-listener Specifies the JMS Exception Listener that is to be notified of any underlying JMS exceptions. The option is a javax.jms.ExceptionListener type. String camel.component.amqp.explicit-qos-enabled Set if the deliveryMode, priority or timeToLive qualities of service should be used when sending messages. This option is based on Spring's JmsTemplate. The deliveryMode, priority and timeToLive options are applied to the current endpoint. This contrasts with the preserveMessageQos option, which operates at message granularity, reading QoS properties exclusively from the Camel In message headers. false Boolean camel.component.amqp.expose-listener-session Specifies whether the listener session should be exposed when consuming messages. false Boolean camel.component.amqp.force-send-original-message When using mapJmsMessage=false Camel will create a new JMS message to send to a new JMS destination if you touch the headers (get or set) during the route. Set this option to true to force Camel to send the original JMS message that was received. false Boolean camel.component.amqp.format-date-headers-to-iso8601 Sets whether date headers should be formatted according to the ISO 8601 standard. false Boolean camel.component.amqp.header-filter-strategy To use a custom org.apache.camel.spi.HeaderFilterStrategy to filter header to and from Camel message. The option is a org.apache.camel.spi.HeaderFilterStrategy type. String camel.component.amqp.idle-consumer-limit Specify the limit for the number of consumers that are allowed to be idle at any given time. 1 Integer camel.component.amqp.idle-task-execution-limit Specifies the limit for idle executions of a receive task, not having received any message within its execution. If this limit is reached, the task will shut down and leave receiving to other executing tasks (in the case of dynamic scheduling; see the maxConcurrentConsumers setting). There is additional doc available from Spring. 1 Integer camel.component.amqp.include-all-j-m-s-x-properties Whether to include all JMSXxxx properties when mapping from JMS to Camel Message. Setting this to true will include properties such as JMSXAppID, and JMSXUserID etc. Note: If you are using a custom headerFilterStrategy then this option does not apply. false Boolean camel.component.amqp.include-sent-j-m-s-message-i-d Only applicable when sending to JMS destination using InOnly (eg fire and forget). Enabling this option will enrich the Camel Exchange with the actual JMSMessageID that was used by the JMS client when the message was sent to the JMS destination. false Boolean camel.component.amqp.jms-key-format-strategy Pluggable strategy for encoding and decoding JMS keys so they can be compliant with the JMS specification. Camel provides two implementations out of the box: default and passthrough. The default strategy will safely marshal dots and hyphens (. and -). The passthrough strategy leaves the key as is. Can be used for JMS brokers which do not care whether JMS header keys contain illegal characters. You can provide your own implementation of the org.apache.camel.component.jms.JmsKeyFormatStrategy and refer to it using the # notation. The option is a org.apache.camel.component.jms.JmsKeyFormatStrategy type. String camel.component.amqp.jms-operations Allows you to use your own implementation of the org.springframework.jms.core.JmsOperations interface. Camel uses JmsTemplate as default. Can be used for testing purpose, but not used much as stated in the spring API docs. The option is a org.springframework.jms.core.JmsOperations type. String camel.component.amqp.lazy-create-transaction-manager If true, Camel will create a JmsTransactionManager, if there is no transactionManager injected when option transacted=true. true Boolean camel.component.amqp.map-jms-message Specifies whether Camel should auto map the received JMS message to a suited payload type, such as javax.jms.TextMessage to a String etc. true Boolean camel.component.amqp.max-concurrent-consumers Specifies the maximum number of concurrent consumers when consuming from JMS (not for request/reply over JMS). See also the maxMessagesPerTask option to control dynamic scaling up/down of threads. When doing request/reply over JMS then the option replyToMaxConcurrentConsumers is used to control number of concurrent consumers on the reply message listener. Integer camel.component.amqp.max-messages-per-task The number of messages per task. -1 is unlimited. If you use a range for concurrent consumers (eg min max), then this option can be used to set a value to eg 100 to control how fast the consumers will shrink when less work is required. -1 Integer camel.component.amqp.message-converter To use a custom Spring org.springframework.jms.support.converter.MessageConverter so you can be in control how to map to/from a javax.jms.Message. The option is a org.springframework.jms.support.converter.MessageConverter type. String camel.component.amqp.message-created-strategy To use the given MessageCreatedStrategy which are invoked when Camel creates new instances of javax.jms.Message objects when Camel is sending a JMS message. The option is a org.apache.camel.component.jms.MessageCreatedStrategy type. String camel.component.amqp.message-id-enabled When sending, specifies whether message IDs should be added. This is just an hint to the JMS broker.If the JMS provider accepts this hint, these messages must have the message ID set to null; if the provider ignores the hint, the message ID must be set to its normal unique value true Boolean camel.component.amqp.message-timestamp-enabled Specifies whether timestamps should be enabled by default on sending messages. This is just an hint to the JMS broker.If the JMS provider accepts this hint, these messages must have the timestamp set to zero; if the provider ignores the hint the timestamp must be set to its normal value true Boolean camel.component.amqp.password Password to use with the ConnectionFactory. You can also configure username/password directly on the ConnectionFactory. String camel.component.amqp.preserve-message-qos Set to true, if you want to send message using the QoS settings specified on the message, instead of the QoS settings on the JMS endpoint. The following three headers are considered JMSPriority, JMSDeliveryMode, and JMSExpiration. You can provide all or only some of them. If not provided, Camel will fall back to use the values from the endpoint instead. So, when using this option, the headers override the values from the endpoint. The explicitQosEnabled option, by contrast, will only use options set on the endpoint, and not values from the message header. false Boolean camel.component.amqp.priority Values greater than 1 specify the message priority when sending (where 0 is the lowest priority and 9 is the highest). The explicitQosEnabled option must also be enabled in order for this option to have any effect. 4 Integer camel.component.amqp.pub-sub-no-local Specifies whether to inhibit the delivery of messages published by its own connection. false Boolean camel.component.amqp.queue-browse-strategy To use a custom QueueBrowseStrategy when browsing queues. The option is a org.apache.camel.component.jms.QueueBrowseStrategy type. String camel.component.amqp.receive-timeout The timeout for receiving messages (in milliseconds). 1000 Long camel.component.amqp.recovery-interval Specifies the interval between recovery attempts, i.e. when a connection is being refreshed, in milliseconds. The default is 5000 ms, that is, 5 seconds. 5000 Long camel.component.amqp.reply-on-timeout-to-max-concurrent-consumers Specifies the maximum number of concurrent consumers for continue routing when timeout occurred when using request/reply over JMS. 1 Integer camel.component.amqp.reply-to-cache-level-name Sets the cache level by name for the reply consumer when doing request/reply over JMS. This option only applies when using fixed reply queues (not temporary). Camel will by default use: CACHE_CONSUMER for exclusive or shared w/ replyToSelectorName. And CACHE_SESSION for shared without replyToSelectorName. Some JMS brokers such as IBM WebSphere may require to set the replyToCacheLevelName=CACHE_NONE to work. Note: If using temporary queues then CACHE_NONE is not allowed, and you must use a higher value such as CACHE_CONSUMER or CACHE_SESSION. String camel.component.amqp.reply-to-concurrent-consumers Specifies the default number of concurrent consumers when doing request/reply over JMS. See also the maxMessagesPerTask option to control dynamic scaling up/down of threads. 1 Integer camel.component.amqp.reply-to-max-concurrent-consumers Specifies the maximum number of concurrent consumers when using request/reply over JMS. See also the maxMessagesPerTask option to control dynamic scaling up/down of threads. Integer camel.component.amqp.reply-to-type Allows for explicitly specifying which kind of strategy to use for replyTo queues when doing request/reply over JMS. Possible values are: Temporary, Shared, or Exclusive. By default Camel will use temporary queues. However if replyTo has been configured, then Shared is used by default. This option allows you to use exclusive queues instead of shared ones. See Camel JMS documentation for more details, and especially the notes about the implications if running in a clustered environment, and the fact that Shared reply queues has lower performance than its alternatives Temporary and Exclusive. ReplyToType camel.component.amqp.request-timeout The timeout for waiting for a reply when using the InOut Exchange Pattern (in milliseconds). The default is 20 seconds. You can include the header CamelJmsRequestTimeout to override this endpoint configured timeout value, and thus have per message individual timeout values. See also the requestTimeoutCheckerInterval option. 20000 Long camel.component.amqp.request-timeout-checker-interval Configures how often Camel should check for timed out Exchanges when doing request/reply over JMS. By default Camel checks once per second. But if you must react faster when a timeout occurs, then you can lower this interval, to check more frequently. The timeout is determined by the option requestTimeout. 1000 Long camel.component.amqp.resolve-property-placeholders Whether the component should resolve property placeholders on itself when starting. Only properties which are of String type can use property placeholders. true Boolean camel.component.amqp.stream-message-type-enabled Sets whether StreamMessage type is enabled or not. Message payloads of streaming kind such as files, InputStream, etc will either by sent as BytesMessage or StreamMessage. This option controls which kind will be used. By default BytesMessage is used which enforces the entire message payload to be read into memory. By enabling this option the message payload is read into memory in chunks and each chunk is then written to the StreamMessage until no more data. false Boolean camel.component.amqp.subscription-durable Set whether to make the subscription durable. The durable subscription name to be used can be specified through the subscriptionName property. Default is false. Set this to true to register a durable subscription, typically in combination with a subscriptionName value (unless your message listener class name is good enough as subscription name). Only makes sense when listening to a topic (pub-sub domain), therefore this method switches the pubSubDomain flag as well. false Boolean camel.component.amqp.subscription-name Set the name of a subscription to create. To be applied in case of a topic (pub-sub domain) with a shared or durable subscription. The subscription name needs to be unique within this client's JMS client id. Default is the class name of the specified message listener. Note: Only 1 concurrent consumer (which is the default of this message listener container) is allowed for each subscription, except for a shared subscription (which requires JMS 2.0). String camel.component.amqp.subscription-shared Set whether to make the subscription shared. The shared subscription name to be used can be specified through the subscriptionName property. Default is false. Set this to true to register a shared subscription, typically in combination with a subscriptionName value (unless your message listener class name is good enough as subscription name). Note that shared subscriptions may also be durable, so this flag can (and often will) be combined with subscriptionDurable as well. Only makes sense when listening to a topic (pub-sub domain), therefore this method switches the pubSubDomain flag as well. Requires a JMS 2.0 compatible message broker. false Boolean camel.component.amqp.task-executor Allows you to specify a custom task executor for consuming messages. The option is a org.springframework.core.task.TaskExecutor type. String camel.component.amqp.test-connection-on-startup Specifies whether to test the connection on startup. This ensures that when Camel starts that all the JMS consumers have a valid connection to the JMS broker. If a connection cannot be granted then Camel throws an exception on startup. This ensures that Camel is not started with failed connections. The JMS producers is tested as well. false Boolean camel.component.amqp.time-to-live When sending messages, specifies the time-to-live of the message (in milliseconds). -1 Long camel.component.amqp.transacted Specifies whether to use transacted mode false Boolean camel.component.amqp.transaction-manager The Spring transaction manager to use. The option is a org.springframework.transaction.PlatformTransactionManager type. String camel.component.amqp.transaction-name The name of the transaction to use. String camel.component.amqp.transaction-timeout The timeout value of the transaction (in seconds), if using transacted mode. -1 Integer camel.component.amqp.transfer-exception If enabled and you are using Request Reply messaging (InOut) and an Exchange failed on the consumer side, then the caused Exception will be send back in response as a javax.jms.ObjectMessage. If the client is Camel, the returned Exception is rethrown. This allows you to use Camel JMS as a bridge in your routing - for example, using persistent queues to enable robust routing. Notice that if you also have transferExchange enabled, this option takes precedence. The caught exception is required to be serializable. The original Exception on the consumer side can be wrapped in an outer exception such as org.apache.camel.RuntimeCamelException when returned to the producer. false Boolean camel.component.amqp.transfer-exchange You can transfer the exchange over the wire instead of just the body and headers. The following fields are transferred: In body, Out body, Fault body, In headers, Out headers, Fault headers, exchange properties, exchange exception. This requires that the objects are serializable. Camel will exclude any non-serializable objects and log it at WARN level. You must enable this option on both the producer and consumer side, so Camel knows the payloads is an Exchange and not a regular payload. false Boolean camel.component.amqp.transfer-fault If enabled and you are using Request Reply messaging (InOut) and an Exchange failed with a SOAP fault (not exception) on the consumer side, then the fault flag on Message#isFault() will be send back in the response as a JMS header with the key org.apache.camel.component.jms.JmsConstants #JMS_TRANSFER_FAULT#JMS_TRANSFER_FAULT. If the client is Camel, the returned fault flag will be set on the org.apache.camel.Message#setFault(boolean). You may want to enable this when using Camel components that support faults such as SOAP based such as cxf or spring-ws. false Boolean camel.component.amqp.use-message-i-d-as-correlation-i-d Specifies whether JMSMessageID should always be used as JMSCorrelationID for InOut messages. false Boolean camel.component.amqp.username Username to use with the ConnectionFactory. You can also configure username/password directly on the ConnectionFactory. String camel.component.amqp.wait-for-provision-correlation-to-be-updated-counter Number of times to wait for provisional correlation id to be updated to the actual correlation id when doing request/reply over JMS and when the option useMessageIDAsCorrelationID is enabled. 50 Integer camel.component.amqp.wait-for-provision-correlation-to-be-updated-thread-sleeping-time Interval in millis to sleep each time while waiting for provisional correlation id to be updated. 100 Long 5.4. Usage As AMQP component is inherited from JMS component, the usage of the former is almost identical to the latter: Using AMQP component // Consuming from AMQP queue from("amqp:queue:incoming"). to(...); // Sending message to the AMQP topic from(...). to("amqp:topic:notify"); 5.5. Configuring AMQP component Starting from the Camel 2.16.1 you can also use the AMQPComponent#amqp10Component(String connectionURI) factory method to return the AMQP 1.0 component with the pre-configured topic prefix: Creating AMQP 1.0 component AMQPComponent amqp = AMQPComponent.amqp10Component("amqp://guest:guest@localhost:5672"); Keep in mind that starting from the Camel 2.17 the AMQPComponent#amqp10Component(String connectionURI) factory method has been deprecated on the behalf of the AMQPComponent#amqpComponent(String connectionURI) : Creating AMQP 1.0 component AMQPComponent amqp = AMQPComponent.amqpComponent("amqp://localhost:5672"); AMQPComponent authorizedAmqp = AMQPComponent.amqpComponent("amqp://localhost:5672", "user", "password"); Starting from Camel 2.17, in order to automatically configure the AMQP component, you can also add an instance of org.apache.camel.component.amqp.AMQPConnectionDetails to the registry. For example for Spring Boot you just have to define bean: AMQP connection details auto-configuration @Bean AMQPConnectionDetails amqpConnection() { return new AMQPConnectionDetails("amqp://localhost:5672"); } @Bean AMQPConnectionDetails securedAmqpConnection() { return new AMQPConnectionDetails("amqp://localhost:5672", "username", "password"); } Likewise, you can also use CDI producer methods when using Camel-CDI AMQP connection details auto-configuration for CDI @Produces AMQPConnectionDetails amqpConnection() { return new AMQPConnectionDetails("amqp://localhost:5672"); } You can also rely on the Camel properties to read the AMQP connection details. Factory method AMQPConnectionDetails.discoverAMQP() attempts to read Camel properties in a Kubernetes-like convention, just as demonstrated on the snippet below: AMQP connection details auto-configuration export AMQP_SERVICE_HOST = "mybroker.com" export AMQP_SERVICE_PORT = "6666" export AMQP_SERVICE_USERNAME = "username" export AMQP_SERVICE_PASSWORD = "password" ... @Bean AMQPConnectionDetails amqpConnection() { return AMQPConnectionDetails.discoverAMQP(); } Enabling AMQP specific options If you, for example, need to enable amqp.traceFrames you can do that by appending the option to your URI, like the following example: AMQPComponent amqp = AMQPComponent.amqpComponent("amqp://localhost:5672?amqp.traceFrames=true"); For reference take a look at the QPID JMS client configuration 5.6. Using topics To have using topics working with camel-amqp you need to configure the component to use topic:// as topic prefix, as shown below: <bean id="amqp" class="org.apache.camel.component.amqp.AmqpComponent"> <property name="connectionFactory"> <bean class="org.apache.qpid.jms.JmsConnectionFactory" factory-method="createFromURL"> <property name="remoteURI" value="amqp://localhost:5672" /> <property name="topicPrefix" value="topic://" /> <!-- only necessary when connecting to ActiveMQ over AMQP 1.0 --> </bean> </property> </bean> Keep in mind that both AMQPComponent#amqpComponent() methods and AMQPConnectionDetails pre-configure the component with the topic prefix, so you don't have to configure it explicitly. 5.7.
