Chapter 134. Spring Redis The producer and consumer are supported. This component allows sending and receiving messages from Redis . Redis is an advanced key-value store where keys can contain strings, hashes, lists, sets and sorted sets. In addition Redis provides pub/sub functionality for inter-app communications. Camel provides a producer for executing commands, a consumer for subscribing to pub/sub messages, and an idempotent repository for filtering out duplicate messages. Prerequisites To use this component, you must have a Redis server running. 134.1. Dependencies When using spring-redis with Red Hat build of Camel Spring Boot, ensure you use the following Maven dependency to have support for auto-configuration: <dependency> <groupId>org.apache.camel.springboot</groupId> <artifactId>camel-spring-redis-starter</artifactId> </dependency> Use the BOM to get the version. <dependencyManagement> <dependencies> <dependency> <groupId>com.redhat.camel.springboot.platform</groupId> <artifactId>camel-spring-boot-bom</artifactId> <version>USD{camel-spring-boot-version}</version> <type>pom</type> <scope>import</scope> </dependency> </dependencies> </dependencyManagement> 134.2. URI Format spring-redis://host:port[?options] 134.3. Configuring Options Camel components are configured on two separate levels: component level endpoint level 134.3.1. Configuring Component Options The component level is the highest level which holds general and common configurations that are inherited by the endpoints. For example, a component may have security settings, credentials for authentication, URLs for network connection. Some components only have a few options, and others may have many. Because components typically have pre-configured defaults that are commonly used, then you may often only need to configure a few options on a component; or none at all. Configuring components can be done with the Component DSL , in a configuration file (application.properties|yaml), or directly with Java code. 134.3.2. Configuring Endpoint Options Where you find yourself configuring the most is on endpoints, as endpoints often have many options, which allows you to configure what you need the endpoint to do. The options are also categorized into whether the endpoint is used as a consumer (from) or as a producer (to), or used for both. Configuring endpoints is most often done directly in the endpoint URI as path and query parameters. You can also use the Endpoint DSL and DataFormat DSL as a type safe way of configuring endpoints and data formats in Java. A good practice when configuring options is to use Property Placeholders , which allows you to not hardcode URLs, port numbers, sensitive information, and other settings. In other words, placeholders allow you to externalize the configuration from your code, and gives more flexibility and reuse. The following two sections lists all the options, firstly for the component followed by the endpoint. 134.4. Component Options The Spring Redis component supports 4 options, which are listed below. Name Description Default Type redisTemplate (common) Autowired Reference to a pre-configured RedisTemplate instance to use. RedisTemplate 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 uses the org.apache.camel.spi.ExceptionHandler to deal with exceptions, that will be logged at WARN or ERROR level and ignored. false boolean lazyStartProducer (producer) Whether the producer should be started lazy (on the first message). By starting lazy, you can use this to allow CamelContext and routes to start up in situations where a producer may otherwise fail during starting and cause the route to fail being started. By starting lazy, Camel's routing error handlers handle any startup failures while routing messages. Beware that when the first message is processed, creating, and starting, the producer may take a little time and prolong the total processing time of the processing. false boolean autowiredEnabled (advanced) Whether autowiring is enabled. This is used for automatic autowiring options (the option must be marked as autowired) by looking up in the registry to find if there is a single instance of matching type, which then gets configured on the component. This can be used for automatic configuring of JDBC data sources, JMS connection factories, and AWS Clients. true boolean 134.5. Endpoint Options The Spring Redis endpoint is configured using URI syntax: with the following path and query parameters: 134.5.1. Path Parameters (2 parameters) Name Description Default Type host (common) Required The host where the Redis server is running. String port (common) Required Redis server port number. Integer 134.5.2. Query Parameters (10 parameters) Name Description Default Type channels (common) List of topic names or name patterns to subscribe to. Multiple names can be separated by a comma. String command (common) Default command, which can be overridden by message header. Notice that the consumer only supports the following commands only: PSUBSCRIBE and SUBSCRIBE. Enum values: PING SET GET QUIT EXISTS DEL TYPE FLUSHDB KEYS RANDOMKEY RENAME RENAMENX RENAMEX DBSIZE EXPIRE EXPIREAT TTL SELECT MOVE FLUSHALL GETSET MGET SETNX SETEX MSET MSETNX DECRBY DECR INCRBY INCR APPEND SUBSTR HSET HGET HSETNX HMSET HMGET HINCRBY HEXISTS HDEL HLEN HKEYS HVALS HGETALL RPUSH LPUSH LLEN LRANGE LTRIM LINDEX LSET LREM LPOP RPOP RPOPLPUSH SADD SMEMBERS SREM SPOP SMOVE SCARD SISMEMBER SINTER SINTERSTORE SUNION SUNIONSTORE SDIFF SDIFFSTORE SRANDMEMBER ZADD ZRANGE ZREM ZINCRBY ZRANK ZREVRANK ZREVRANGE ZCARD ZSCORE MULTI DISCARD EXEC WATCH UNWATCH SORT BLPOP BRPOP AUTH SUBSCRIBE PUBLISH UNSUBSCRIBE PSUBSCRIBE PUNSUBSCRIBE ZCOUNT ZRANGEBYSCORE ZREVRANGEBYSCORE ZREMRANGEBYRANK ZREMRANGEBYSCORE ZUNIONSTORE ZINTERSTORE SAVE BGSAVE BGREWRITEAOF LASTSAVE SHUTDOWN INFO MONITOR SLAVEOF CONFIG STRLEN SYNC LPUSHX PERSIST RPUSHX ECHO LINSERT DEBUG BRPOPLPUSH SETBIT GETBIT SETRANGE GETRANGE PEXPIRE PEXPIREAT GEOADD GEODIST GEOHASH GEOPOS GEORADIUS GEORADIUSBYMEMBER SET Command connectionFactory (common) Reference to a pre-configured RedisConnectionFactory instance to use. RedisConnectionFactory redisTemplate (common) Reference to a pre-configured RedisTemplate instance to use. RedisTemplate serializer (common) Reference to a pre-configured RedisSerializer instance to use. RedisSerializer bridgeErrorHandler (consumer (advanced)) Allows for bridging the consumer to the Camel routing Error Handler, which means any exceptions that occurred while the consumer is trying to pick up incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler. The consumer defaults to use the org.apache.camel.spi.ExceptionHandler to deal with exceptions. These exceptions log at WARN or ERROR level and ignored. False Boolean exceptionHandler (consumer (advanced)) To let the consumer use a custom ExceptionHandler. If you enable the bridgeErrorHandler option, this option is not used. By default, the consumer will deal with exceptions, that will be logged at WARN or ERROR level and ignored. ExceptionHandler exchangePattern (consumer (advanced)) Sets the exchange pattern when the consumer creates an exchange. Enum values: InOnly InOut InOptionalOut ExchangePattern listenerContainer (consumer (advanced)) Reference to a pre-configured RedisMessageListenerContainer instance to use. RedisMessageListenerContainer lazyStartProducer (Producer (advanced)) Whether the producer should be started lazy (on the first message). By starting lazy, you can use this to allow CamelContext and routes to start up in situations where a producer may otherwise fail during starting and cause the route startup to fail. By deferring this startup to be lazy, the startup failure can be handled during routing messages via Camel's routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing. False Boolean 134.6.

Spring Boot Auto-Configuration The component supports 5 options, which are listed below. Name Description Default Type camel.component.spring-redis.autowired-enabled Whether autowiring is enabled. This is used for automatic autowiring options (the option must be marked as autowired) by looking up in the registry to find if there is a single instance of matching type, which then gets configured on the component. This can be used for automatically configure JDBC data sources, JMS connection factories, AWS Clients, etc. True Boolean camel.component.spring-redis.bridge-error-handler Allows for bridging the consumer to the Camel routing Error Handler, which means any exceptions that occur while the consumer is trying to pick up incoming messages, or the likes, will 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 camel.component.spring-redis.enabled Whether to enable auto configuration of the spring-redis component. This is enabled by default. Boolean camel.component.spring-redis.lazy-start-producer Whether the producer should be started lazy (on the first message). By starting lazy, you can allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail start up. By deferring this startup to be lazy, the startup failure can be handled during routing messages via Camel's routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing. False Boolean camel.component.spring-redis.redis-template Reference to a pre-configured RedisTemplate instance to use. The option is an org.springframework.data.redis.core.RedisTemplate type.
