apache-camel | I have a spring boot application that publish a rest endpoint to receives xml messages using apache camel, below the relevant part of the code corresponding to the configuration of the route: <code> restConfiguration() .component(';servlet';) .bindingMode(RestBindingMode.auto); rest(';/api/';).description(';REST Message Endpoint Service';) .id(';rest-producer-route';) // Accept post requests at /api/message .post(';/message';) // request in xml format .consumes(';application/xml';) .to(';direct:remoteService';); from(';direct:remoteService';) // RABBIT_URI = ';spring-rabbitmq:%s?routingKey=%s&;arg.queue.autoDelete=false';; .to(String.format(CamelConfiguration.RABBIT_URI, ';coreEngine';, ';coreEngine';)) .setHeader(Exchange.HTTP_RESPONSE_CODE, constant(201)); </code> When trying to send a message in xml format using Postman, after about 30 seconds I get a 500 error, with the following exception: <code>org.springframework.amqp.core.AmqpReplyTimeoutException: Reply timed out at org.springframework.amqp.rabbit.AsyncRabbitTemplate$RabbitFuture$TimeoutTask.run(AsyncRabbitTemplate.java:762) ~[spring-rabbit-2.4.6.jar:2.4.6] at org.springframework.scheduling.support.DelegatingErrorHandlingRunnable.run(DelegatingErrorHandlingRunnable.java:54) ~[spring-context-5.3.22.jar:5.3.22] at java.base/java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:515) ~[na:na] at java.base/java.util.concurrent.FutureTask.run(FutureTask.java:264) ~[na:na] at java.base/java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.run(ScheduledThreadPoolExecutor.java:304) ~[na:na] at java.base/java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1128) ~[na:na] at java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:628) ~[na:na] at java.base/java.lang.Thread.run(Thread.java:829) ~[na:na]</code> However on the rabbitmq server the message was successfully saved to the coreEngine queue. I don't need any transformation to be done, the goal of the endpoint is simply to receive messages in xml format and store them in a rabbitmq queue. From what I could see, an AsyncRabbitTemplate is used, would that be the cause of the problem? What should I do to configure it correctly? | This is because the exchange pattern by default is expecting a reply, hence camel is using the <code>AsyncRabbitTemplate.sendAndReceive</code>. If you just want to fire and forget, set the exchange pattern to <code>ExchangePattern.InOnly</code> for Camel to use <code>RabbitTemplate.send</code>. You code should be changed to, <code>from(';direct:remoteService';) // RABBIT_URI = ';spring-rabbitmq:%s?routingKey=%s&;arg.queue.autoDelete=false';; .to(ExchangePattern.InOnly, String.format(CamelConfiguration.RABBIT_URI, ';coreEngine';, ';coreEngine';)) .setHeader(Exchange.HTTP_RESPONSE_CODE, constant(201)); </code> Refer the Apache Camel SpringRabbitMQProducer source code SpringRabbitMQProducer |
apache-camel | Good Morning! These days I'm trying to learn how to use Apache Camel. With a course on Udemy it was pretty simple to learn how to do standard operation in route. Now I wish to learn the use of the Rest integration, but I don't understand the differences between the exposition of an endpoint with <code>rest(';/someRoute';) .consumes(';application/json';).produces(';application/json';) .get().outType(String.class); </code> or <code>from(';rest:get:/rest-route/get-route';) .routeId(';ReceiverRoute';) .transform().constant(';Bye World';) .log(';${body}';); </code> Can anyone explain which are the differences between them and which is the best way to expose the endpoint? Why? I can't understand neither the construction of the rest() route and how to use the route() instruction. I tried to work on this example in another stackoverflow post: In Apache Camel what does ';route()'; do in a restful declaration? but the same route in my class is not correct and I can't understand why. <code> rest(';/someRoute';) .id(';someRoute';) .description(';Some description';) .post() .consumes(';text/plain';) .produces(';text/plain';) .route() //HERE I have the error: Cannot resolve method 'route' in 'RestDefinition' .routeId(';someRoutePost';) .to(';direct:toSomewhere';) .end() .endRest() .get() .route() .routeId(';someRouteGet';) .setHeader(Exchange.HTTP_RESPONSE_CODE, constant(405)) .setBody(constant(';GET not allowed on this route';)) .end() .endRest(); </code> I'm working with Springboot 2.7.3 and Camel 3.18.1 with these dependencies: <code> <dependency>; <groupId>;org.apache.camel.springboot</groupId>; <artifactId>;camel-spring-boot-starter</artifactId>; <version>;${camel.version}</version>; </dependency>; <dependency>; <groupId>;org.apache.camel.springboot</groupId>; <artifactId>;camel-http-starter</artifactId>; <version>;${camel.version}</version>; </dependency>; <dependency>; <groupId>;org.apache.camel.springboot</groupId>; <artifactId>;camel-servlet-starter</artifactId>; <version>;${camel.version}</version>; </dependency>; <dependency>; <groupId>;org.apache.camel.springboot</groupId>; <artifactId>;camel-rest-starter</artifactId>; <version>;${camel.version}</version>; </dependency>; </code> | Can anyone explain which are the differences between them and which is the best way to expose the endpoint? Why?The method above uses Camel Rest-DSL which allows you to define rest endpoints using java instead of fiddling URI Strings. The method below uses camel-rest component which works almost identically except for the fact that you use URI strings to configure it. It's possible that Rest-DSL uses this under the hood. The example you're referring to used camel version 3.14.0 but it seems both <code>.route()</code> and <code>endRest()</code> methods have been quietly removed from RestDefitinion which causes the exception <code>Cannot resolve method 'route' in 'RestDefinition</code>. Instead of <code>route()</code> you should use <code>to(';direct:endpointName';)</code> instead. My guess is that developers wanted to move most of the routing logic away from the RestDSL to keep it clean. Here's example for Camel 3.18.1 <code> // What I used to test this restConfiguration() .component(';undertow';) .host(';localhost';) .port(8091);// http://localhost:8091/api/hello rest(';/api';) .description(';Some description';) .post(';/hello';) .consumes(';text/plain';) .produces(';text/plain';) .to(';direct:someRoutePost';) .get(';/hello';) .produces(';text/plain';) .to(';direct:someRouteGet';);from(';direct:someRouteGet';) .routeId(';someRouteGet';) .setHeader(Exchange.HTTP_RESPONSE_CODE, constant(200)) .setBody(constant(';Hello world';));from(';direct:someRoutePost';) .routeId(';someRoutePost';) .setHeader(Exchange.HTTP_RESPONSE_CODE, constant(405)) .setBody(constant(';POST not allowed on this route';)); </code> Tested by generating project using maven <code>camel-archetype-spring-boot</code> archetype version <code>3.18.1</code>, added in following dependency. <code><dependency>; <groupId>;org.apache.camel.springboot</groupId>; <artifactId>;camel-undertow-starter</artifactId>; </dependency>; </code> |
apache-camel | I'm trying to use the camel-bean-validator dependency in my project but I have a problem with group validation. I'm using a springboot project with spring-boot-starter-parent 2.7.3 and these dependencies in pom.xml: <code><dependency>; <groupId>;org.apache.camel.springboot</groupId>;

BasicValidation.class) private Long id; @NotBlank(groups = AdvancedValidation.class) private String name; @NotBlank private String value;} </code> And I created two interfaces for validation: <code> public interface AdvancedValidation { } </code> <code> public interface AdvancedValidation { } </code> When I want to use a standard validation like this in my route the application starts without problem: <code>@Component public class ValidationRoute extends RouteBuilder { @Override public void configure() throws Exception { from(';timer:val-timer?period=5000';) .process(new Processor() { @Override public void process(Exchange exchange) throws Exception { SimpleDto simpleDto = new SimpleDto(); exchange.getIn().setBody(simpleDto); } }) .log(';Setted body: ${body}';) .to(';bean-validator://x';) .log(';Validated message';); } }</code> but when I change the validation endpoint in: <code>.to(';bean-validator://x?group=AdvancedValidation';) </code> like in the example in Apache Camel documentation, here: https://camel.netlify.app/components/latest/bean-validator-component.html the application stop working and this is the error I have starting it:

Using the same interfaces and the same project in a RestController and validating it with @Valid or @Validated(AdvancedValidation.class) worked correctly, so this is a Camel issue | I probably solved it by using all the class path related to group: <code>.to(';bean-validator://x?group=com.application.dto.validation.group.AdvancedValidation';) </code> |
apache-camel | I am new to using Apache camel with Spring boot and try to implement a basic route in which, I want to filter out first whether the file has json contents or xml contents and based upon it, I want to save the file in some specific folder. I make my service instance up and then hit its post endpoint using postman with JSON content. My service saves that file to some folder location with txt extension. I have created the route in the service which picks up the file and checks if it is not empty, it will transform the contents in to XML format and store it to some folder. Route for this thing is below: <code>public class OutboundRoute extends RouteBuilder { Predicate p1=body().isNotNull(); Predicate p2=body().isNotEqualTo(';';); Predicate predicateGroup=PredicateBuilder.and(p1,p2); String inputFilePath=';file:C:\\Users\\StorageFolder\\Input?noop=true';; String outputFilePathForJson=';file:C:\\Users\\StorageFolder\\JsonFolderOutput?delete=true';; @Override public void configure() throws Exception { from(inputFilePath) .routeId(';readingJsonFromFile';) .choice() .when(predicateGroup) .log(';Before converting to XML: ${body}';) .unmarshal().json(JsonLibrary.Jackson, Message.class) .marshal().jacksonXml(true) .log(LoggingLevel.INFO, ';Payload after converting to xml = ${body}';) .to(outputFilePathForJson) .otherwise() .log(';Body is Empty!!';) .end(); } } </code> Now I want to implement this thing for xml also for better understanding. I want that I can hit my service using postman with either XML or JSON content. The route should pick the file and check it. If it has XML contents, route should convert its contents to JSON and store it to JSON folder but if it has JSON contents, route should convert its contents to XML and store it to XML folder. I need help with this thing. Main thing is that when I hit the service using postman, service will always store the file with txt extension only. So, I need help with a way to find that content of file is of JSON format or XML format. Also, I tried finding some content about learning apache camel but everywhere found basic tutorials only. Can someone recommend some platform where I can learn how to write complex routes? | I won't say its a good answer but an easy alternative I would say. What I did is, I created a processor which will check first character of file and if its ';{';, then its json and if its ';<';, then its XML. So, after detecting, I would add a header to camel route exchange as ';Type';: json or xml or unknown And using camel's ';simple'; language,I will check the header and based on that, in the route, I will do the processing. I am adding below files for better reference. Predicates used in route: <code>private Predicate notNull=body().isNotNull(); private Predicate notEmpty=body().isNotEqualTo(';';); private Predicate checkEmptyFile=PredicateBuilder.and(notNull,notEmpty); private Predicate checkIfJsonContents=header(';Type';).isEqualTo(';json';); private Predicate checkIfXmlContents=header(';Type';).isEqualTo(';xml';); private Predicate checkIfFileHasJsonContents=PredicateBuilder.and(checkEmptyFile,checkIfJsonContents); private Predicate checkIfFileHasXmlContents=PredicateBuilder.and(checkEmptyFile,checkIfXmlContents);</code> Route: <code>from(inputFilePath) .routeId(';readingJsonFromFile';) .routeDescription(';This route will assign a file type to file based on contents and then save it in different folder based on contents.';) .process(fileTypeDetectionProcessor) .log(';Added file type to header as: ${header.Type}';) .choice() .when(checkIfFileHasJsonContents) .log(';Payload before converting to XML: ${body}';) .unmarshal().json(JsonLibrary.Jackson, Message.class) .marshal().jacksonXml(true) .log(LoggingLevel.INFO, ';Payload after converting to xml = ${body}';) .to(outputFilePathForXml) .when(checkIfFileHasXmlContents) .log(';Payload before converting to JSON: ${body}';) .unmarshal().jacksonXml(Message.class,true) .marshal().json(true) .log(LoggingLevel.INFO, ';Payload after converting to JSON = ${body}';) .to(outputFilePathForJson) .otherwise() .log(';Unreadable format or empty file!!';) .to(outputFilePathForBadFile) .end(); </code> Processor: <code>public class FileTypeDetectionProcessor implements Processor { @Override public void process(Exchange exchange) throws Exception { if(exchange.getIn().getBody(String.class).startsWith(';{';)) exchange.getIn().setHeader(';Type';,';json';); else if(exchange.getIn().getBody(String.class).startsWith(';<';)) exchange.getIn().setHeader(';Type';,';xml';); else exchange.getIn().setHeader(';Type';,';unknown';); } } </code> |
apache-camel | I am new to Apache Camel. I need to split a file line by line and to do some operation on each lines. At the end I need a footer line with information from previous lines (number of lines and sum of the values of a column) My understanding is that I should be using an aggregation strategy, so I tried something like that: <code>.split(body().tokenize(';\r | ';), sumAggregationStrategy) .process(';fileProcessor';) </code> In my aggregation strategy I just set two headers with the incremented values: <code>newExchange.getIn().setHeader(';sum';, sum); newExchange.getIn().setHeader(';numberOfLines';, numberOfLines); </code> And in the processor I try to access those headers: <code>int sum = inMessage.getIn().getHeader(';sum';, Integer.class); int numberOfLines = inMessage.getIn().getHeader(';numberOfLines';, Integer.class); </code> There are two problems. First of all the aggregation strategy seem to be called after the first iteration of the processor. Second, my headers don't exist in the processors, so I can't access the information I need when I am at the last line of the file. The headers do exist in the oldExchange of the aggregators though. I think I can still do it, but I would have to create a new processor just for the purpose of making the last line of the file. Is there something I'm missing with the aggregation strategies ? Is there a better way to do this ? | An aggregator will be called for every iteration of the split. This is how they are supposed to work. The reason you don't see the headers within the processor is, headers live and die with the message and not visible outside. You need to set the 'sum' and 'numberOfLines' as exchange properties instead. Because every iteration within a split results in an exchange, you need get the property from old exchange and set them again in the new exchange to pass them to subsequent components in the route. This is how you could do, AggregationStrategy: <code>public class SumAggregationStrategy implements AggregationStrategy { public Exchange aggregate(Exchange oldExchange, Exchange newExchange) { long sum = 0; long numberOfLines = 0; if(oldExchange != null) { sum = (Long) oldExchange.getProperty(';sum';); numberOfLines = oldExchange.getProperty(';numberOfLines ';); } sum = sum + ((Line)newExchange.getIn().getBody()).getColumnValue(); numberOfLines ++; newExchange.setProperty(';sum';, sum); newExchange.setProperty(';numberOfLines';,numberOfLines); oldExchange.setProperty(';CamelSplitComplete';, newExchange.getProperty(';CamelSplitComplete';)); //This is for the completion predicate return newExchange; } } </code> Route: <code> .split(body().tokenize(';\r | ';),sumAggregationStrategy) .completionPredicate(simple(';${exchangeProperty.CamelSplitComplete} == true';)) .process(';fileProcessor';).to(';file:your_file_name?fileExist=Append';); </code> Processor: <code>public class FileProcessor implements Processor { public void process(Exchange exchange) throws Exception { long sum = exchange.getProperty(';sum';); long numberOfLines = exchange.getProperty(';numberOfLines';); String footer = ';Your Footer String';; exchange.getIn().setBody(footer); } } </code> |

apache-camel | I'm trying to get in touch with Apache Camel, but it's behaviour is so far confusing. For example, I'm using platformHttp and declare a route under which my endpoint should be available. <code>from(platformHttp(';/api/test';)) .to(';https:google.com?bridgeEndpoint=true';) .setBody(simple(';${body}';)); </code> Calling it will call the sub-route https://google.com/api/test instead of https://google.com Why is that and how would I prevent Apache Camel from taking the route and appending it to the called route in my .to() ? | To prevent the HTTP exchange headers (I.e ones with names prefixed with <code>CamelHttp</code>) being propagated from the <code>platform-http</code> endpoint to the <code>http</code> endpoint, you can remove them like this. <code>from(platformHttp(';/api/test';)) .removeHeaders(';CamelHttp*';) .to(';https:google.com?bridgeEndpoint=true';) .setBody(simple(';${body}';)); </code> There's an FAQ article for this topic on the Camel website: https://camel.apache.org/manual/faq/how-to-remove-the-http-protocol-headers-in-the-camel-message.html |
apache-camel | I have a camel route that goes through a series of processors which each call some service. If processor 1 fails gracefully, I no longer want to call processors 2-5, but I do want to call <code>consolidateResponse</code>. The same for all the other processors.

apache-camel | I've recently been working on setting up a project to use Azure and part of that involves requesting a token to access a REST API.

When your application then receives this message and invokes <code>getJMSReplyTo()</code> it will receive a <code>javax.jms.Queue</code> implementation (i.e. <code>ActiveMQQueue</code>) and then you can use <code>getQueueName()</code> to get the <code>String</code> name of the queue if necessary. |

apache-camel | I am reading and processing 2 files from 2 different file locations and comparing the content. If 2nd file is not available , the rest of the process execute with 1st file. If 2nd file is available, comparison process should happen. For this I am using camel pollEnrich, but here the problem is that, camel is picking the 2nd file at first time only. Without restarting the camel route 2nd file is not getting picked up even if it is present there. After restarting the camel route it is working fine, but after that its not picking the 2nd file. I am moving the files to different locations after processing it. Below is my piece of code, <code>from(';sftp:'; + firstFileLocation + ';?privateKeyFile='; + ppkFileLocation + ';&;username='; + sftpUsername + ';&;readLock=changed&;idempotent=true&;move='; + firstFileArchiveLocation) .pollEnrich(';sftp:'; + secondFileLocation + ';?privateKeyFile='; + ppkFileLocation + ';&;username='; + sftpUsername + ';&;readLock=changed&;idempotent=true&;fileExist=Ignore&;move=';+ secondFileLocationArchive ,10000,new FileAggregationStrategy()) .routeId(';READ_INPUT_FILE_ROUTE';) </code> Need help. | You're setting <code>idempotent=true</code> in the sftp consumer, which means camel will not process the same file name twice. Since you're moving the files, it would make sense to set <code>idempotent=false</code>. Quoted from camel documentationOption to use the Idempotent Consumer EIP pattern to let Camel skip already processed files. Will by default use a memory based LRUCache that holds 1000 entries. If noop=true then idempotent will be enabled as well to avoid consuming the same files over and over again. |
apache-camel | Essentially - how is it possible to use Camel's Aggregator with a File based input? By default, when an Exchange created using the File component's input completes its Route the file is moved to <code>$inputLocation/.camel/</code>. However, when using an Aggregator, after the Exchange goes through the aggregation step it goes on to complete the remainder of the Route outside of the Aggregation step (which there may or may not be). This means that the Exchange finishes the Route and if a File Consumer was used it causes the file to be moved to <code>$inputLocation/.camel/</code>. At some later time the Aggregator will complete and when it does so the aggregated File references will be invalid, because the file was moved on disk when the regular Exchange completed the Route. The following depicts a simple Route that shows the issue. The referenced Processor <code>doSomethingWithTheAggregatedFiles</code> will find that the files in question do not exist at their stated location (as they have already been moved (to <code>workdirs/in/.camel/</code>): <code> @Override public void configure() throws Exception { from(';file:workdirs/in/';) .aggregate(constant(true), AggregationStrategies.groupedExchange()) .completionTimeout(10*1000) // 10 seconds .process(';doSomethingWithTheAggregatedFiles';) .end() .log(';file completed route: $simple{header[CamelFileName]}';) .end(); } </code> Is there something missing here? Is there no way to get it to ';wait'; until the aggregated exchange completes? Looking at the <code>ZipAggregationStrategy</code> I see that it doesn't suffer this issue because it reads the content of the files during the aggregation step and adds it into the ZIP file - essentially taking a copy of the data as the aggregation step occurs. Preferably I do not want to take a copy, as my input may be large. | You could set the file consumer's noop to <code>true</code> and implement a simple processor to move the files after your aggregation is complete. <code>.process(e ->; { String name = e.getIn().getHeader(';CamelFileNameConsumed';, String.class); Files.move( Path.of(name), Path.of(';.camel';).resolve(';name';)); }) </code> Another solution that might work for you is to force the Aggregator to run in the same thread as its caller: <code>.aggregate(constant(true), AggregationStrategies.groupedExchange()) .executorService(new SynchronousExecutorService()) ... </code> This results in all aggregations completing prior to the File component being notified that the route is complete. |
apache-camel | I am new to apache camel features. So I have a problem with the DefaultErrorHandler in our project. There are some errors in which we are not using any custom error handler. Whenever an exception occurs, apache camel logs it and this log level is ERROR. Apache camel is handling failure through DefaultErrorHandler which propagates exceptions back to the caller since there isn’t any custom error handler. This errors are like ';User not found'; so this shouldn't be a ERROR, this can be a WARN or INFO. Since we are not handling it, DefaultErrorHandler by Apache Camel handles it. The error log like this on the server: <code> main 2022-08-05 15:24:43.537 ERROR [user-manager] 1 --- [nio-8080-exec-5] o.a.c.p.e.DefaultErrorHandler : Failed delivery for (MessageId:-0000000 on Exc │ │ │ main +[ │ │ │ main +[ Message History (complete message history is disabled) │ │ │ main +[ --------------------------------------------------------------------------------------------------------------------------------------- │ │ │ main +[ RouteId ProcessorId Processor Elapsed (ms) │ │ │ main +[ [PostUserToIdentity] [PostUserToIdentity] [from[direct://business.postUserToIdentity] ] [ 27] │ │ │ main +[ ... │ │ │ main +[ [PostUserToIdentity] [to58 ] [direct:postUserToIdentityRequestedInternal ] [ 0] │ │ │ main +[ │ │ │ main +[ Stacktrace │ │ │ main +[ --------------------------------------------------------------------------------------------------------------------------------------- │ │ │ main +[ │ │ │ main │ │ │ main com.user.manager.exception.ConflictException: User already exists </code> So, I wrote a Custom Handler and a RouteClass which extends the RouteBuilder with the proper Camel OnException clause. OnConflictExceptionRoute Class <code>@Component public class OnConflictExceptionRoute extends RouteBuilder { @Override public void configure() { log.info(';Configuring extended create user by context route';); onException(ConflictException.class) .process(new ConflictExceptionHandler()) .handled(true); from(';direct:business.postUserToIdentity';) .routeId(';PostUserToIdentity';) .onException(ConflictException.class) .process(new ConflictExceptionHandler()); } } </code> Custom Error Handler <code>@Slf4j public class ConflictExceptionHandler implements Processor { @Override public void process(Exchange exchange) { log.info(';USER ALREADY EXISTS!';); throw new ConflictException().withMessage(';USER ALREADY EXISTS!';); } } </code> At the application startup, I could see that the Configure method in the RouteClass is triggered. But when I am triggering the flow, I am still seeing the same error is handling by the DefaultErrorHandler. Why it is not working? Is there any missing configuration? Thanks. | So after a deep analysis, I found that I'd to resolve this issue with the service that we called in the application by extending the RouteBuilder class like this. <code> @Override protected ErrorHandlerFactory createErrorHandlerBuilder() { DefaultErrorHandlerBuilder errorHandlerBuilder = super.defaultErrorHandler(); // Changed from ERROR because it is expected that the service handles the exception. errorHandlerBuilder.setLevel(LoggingLevel.INFO.toString()); RedeliveryPolicyDefinition policy = new RedeliveryPolicyDefinition(); policy.setDisableRedelivery(';false';); policy.setRetriesExhaustedLogLevel(getRetriesExhaustedLogLevel().toString()); errorHandlerBuilder.setRedeliveryPolicy(policy); return errorHandlerBuilder; } </code> Note : ExhaustedLogLevel is setted as DEBUG. |
apache-camel | I use Apache Camel in a Spring Boot Java project. I have to parse a csv and split the lines with a separator. I use camel bindy to parse the csv and read it as a pojo bean class. Here is how I configure the camel bindy <code>@CsvRecord( separator = ';,'; ) public Class MyClass { } </code> Here is my question: how can I change the separator value dynamically, reading it from a property?

apache-camel | I've found here that the default behaviour for FromXmlParser.Feature.EMPTY_ELEMENT_AS_NULL has changed from true (2.9 - 2.11) to false (2.12 onwards), so from that version no automatic coercion is done from empty elements like into null. I was using Apache Camel 2.25 and that version had this feature enabled by default but now, with this change, is disabled in Camel 3.x. How can I enable it in back in Camel 3 using XML DSL? I know using XMLMapper is easy enough: <code>XmlMapper xmlMapper = new XmlMapper(); xmlMapper.configure(FromXmlParser.Feature.EMPTY_ELEMENT_AS_NULL, true); </code> But in Camel XML DSL the allowed enums are only the ones from SerializationFeature, DeserializationFeature and MapperFeature. I've tried with some of them but with no luck. <code><unmarshal>; <jacksonxml disableFeatures=';FAIL_ON_UNKNOWN_PROPERTIES'; enableFeatures=';ACCEPT_EMPTY_STRING_AS_NULL_OBJECT,ACCEPT_EMPTY_ARRAY_AS_NULL_OBJECT'; unmarshalTypeName=';com.my.class.Result'; include=';NON_NULL'; />; </unmarshal>; </code> | You can set a custom xmlMapper on the jacksonxml element, the attribute is called ';xmlMapper'; you can then reference your custom XmlMapper which should be declared as a bean, but this is important, you must include a # before the bean name or else the object mapper will not be looked up and will be set to null and a default one will be created. <code> @Bean public XmlMapper customXMLMapper(){ return XmlMapper.builder() .configure(EMPTY_ELEMENT_AS_NULL, true) .configure(FAIL_ON_UNKNOWN_PROPERTIES, false) .build(); } </code> <code><unmarshal>; <jacksonxml unmarshalTypeName=';com.myclass.Result'; xmlMapper=';#customXMLMapper';/>; </unmarshal>; </code> |
apache-camel | For my Kotlin application with Spring-Boot 2.7.0 and Apache Camel 3.17.0, I am running into a rather surprising issue: I have a set of JUnit 5 test cases that individually run fine (using <code>mvn test -DTest=';MyTest';</code>); but when run in batch via <code>mvn test</code> or in IntelliJ IDEA, some test cases fail with <code>org.apache.camel.FailedToCreateRouteException... because of Cannot set tracer on a started CamelContext</code>. The funny thing is, that these test cases do not have tracing enabled. My test setup looks like the following for most of the tests: <code>@CamelSpringBootTest @SpringBootTest( classes = [TestApplication::class], properties = [';camel.springboot.java-routes-include-pattern=**/SProcessingTestRoute';] ) @TestConstructor(autowireMode = TestConstructor.AutowireMode.ALL) @UseAdviceWith internal class ProcessingTest( val template: FluentProducerTemplate, @Value(';classpath:test-resource';) private val TestResource: Resource, val camelContext: CamelContext ) { @EndpointInject(';mock:result';) lateinit var resultMock: MockEndpoint @Test fun `test my route`() { AdviceWith.adviceWith(camelContext, ';processing-route';) { route ->; route.weaveAddLast().to(';mock:result';) } resultMock.expectedCount = 1 camelContext.start() // ... // here comes the actual test } } </code> There are a couple of tests where I do not advice routes; i.e., these test cases do not have the <code>@AdviceWith</code> annotation, and these test cases do not fail during the batch run. Debugging this issue is hard; therefore, I would highly appreciate any pointers, hints, or hypothesis for potential causes, and ideas on what to try to narrow down the problem! | You probably need a fresh camel context for each test. Try adding <code>@DirtiesContext</code> to each test class. If that doesn't work, add it to each test method. |
apache-camel | In camel version 3.16.0 embedded routes were removed from the rest definition: https://issues.apache.org/jira/browse/CAMEL-17675 This introduces this problem: Parsing Multipart as a Stream We expose a rest endpoint where a user can upload a <code>multipart/form-data</code> request which has metadata and files alike. Until now we used apache to parse the request and save the file parts into a temporary folder: <code>Message message = exchange.getMessage(); HttpServletRequest request = message.getBody(HttpServletRequest.class); ServletFileUpload servletFileUpload = new ServletFileUpload(new DiskFileItemFactory()); List<FileItem>; items = servletFileUpload.parseRequest(request); // Iterate over items, save files, parse meta-data etc. </code> This now throws an exception because the InputStream of the Request is closed. Using a different way of parsing the multipart request is unfortunatelly not really an option because we potentially receive very big files, that we just have to read via a Stream. The fact that its closed means all the content has been read and all that file data is in the ram which will not go well. | I found the solution. In order for the stream to stay open you have to tell camel to not use stream caching: <code>getCamelContext().setStreamCaching(false); </code> When using spring Boot the alternative is setting it via the config: <code>camel: springboot: stream-caching-enabled: false </code> Both will disable stream caching globally. I have not found a way to diable it for just one rest endpoint, but it will do the trick |
apache-camel | My project need a split then aggregate operation rather than the integrated split+aggregate but I don't have any clue about how propagate an exception to stop further processing. In the example below I'll need to be able to not make the last log if an exception was thrown in post aggregation. <code>@RunWith(SpringJUnit4ClassRunner.class) public class AggregationExceptionTest extends CamelTestSupport { private final Logger LOGGER = LoggerFactory.getLogger(AggregationExceptionTest.class); @Override protected RouteBuilder createRouteBuilder() throws Exception { return new RouteBuilder() { @Override public void configure() throws Exception { from(';direct:start';) .split(body()).streaming().stopOnException().parallelProcessing() .aggregate(new AggregationStrategy() { @Override public Exchange aggregate(Exchange oldExchange, Exchange newExchange) { if (newExchange.getException() != null) { LOGGER.info(';exception propagated';); } return oldExchange==null?newExchange:oldExchange; } }).constant(true) .completionSize(1).completionTimeout(500) .log(LoggingLevel.INFO, LOGGER, ';Aggreg ${body}';) .throwException(Exception.class, ';propagate plz';) .end() .end() .process(e ->; { LOGGER.info(';I don't want to be seen, because of {}';, e.getException()); }); } }; } @Test public void test1() throws InterruptedException { template.sendBody(';direct:start';, Arrays.asList(';A';, ';B';, ';C';, ';D';)); Thread.sleep(5000); } } </code> The exception thrown is never visible in the aggregate method. | I'm not sure this is possible. Aggregator output is completely separated from the route that invokes it. It also operates in its own thread, unless you supply it a <code>SynchronousExecutorService</code> instance. You might try the <code>SynchronousExecutorService</code> option: <code>.aggregate(constant(1), new YourAggregator()) .executorService(new SynchronousExecutorService()) </code> Before your split, set a <code>Map</code> instance in the header with a key called <code>exception</code>, value null initially. Then in the aggregator output, if an exception occurs, update that Map key with the exception. Then in your split, you can check the Map key for an Exception instance, and do whatever you want, e.g., splitter's <code>stopOnException</code> option. |

apache-camel | I'm new to Apache Camel and learning its basics. I'm using Yaml DSL I have a TGZ file which includes 2 small CSV files. I am trying to decompress the file using gzipDeflater, but when I print the body after the extraction, it includes some data about the CSV (filename, my username, some numbers) - that is preventing me from parsing the CSV only by its known columns. since the extracted file includes lines that were not included in the original CSV, whenever one of those lines is processed, i get an exception. Is there a way for me to ';ignore'; those lines, or perhaps another functionality of Apache Camel that will let me access only the content of those CSV's? Thanks! | You probably have a gzipped tar file, which is a slightly different thing than just a deflate compressed file.

Probably this should ends in another question, I don't think is related to my problem.

I'm probably doing something wrong with the uri syntax and how I compose it but cannot figure it out. | I'm working with Stefano, the issue is related to camel implementation with minio component. The solution is the following. The recevivedBody is an interface with overloaded methods if the timeout is required set the minimum timeout to 1100 millis or the result will be null, if is not required just use the method without timeout. With Timeout <code>ConsumerTemplate template = context.createConsumerTemplate(); byte[] content = template.receiveBody(uri, 1100, byte[].class); </code> Without timeOut <code>ConsumerTemplate template = context.createConsumerTemplate(); byte[] content = template.receiveBody(uri, byte[].class); </code> |
apache-camel | I'm using Camel JPA endpoints to poll a database and copy the data to a second one. To not poll duplicates, I'm planning to save the highest ID of the copied data and only poll data with an ID higher than that one. To save a few database writes, I want to write back the highest ID after the current polling / copying run is over, not for every single data element. I can access the element (and its ID) in the Camel Route class: <code> private Long startId = 0L; private Long lastId = 0L; from(';jpa://Data';).routeId(';dataRoute';) .onCompletion().onCompleteOnly().process(ex ->; { if (lastId >; startId) { startId = lastId; logger.info(';New highest ID: {}';, startId); } }).end() .process(ex ->; { Data data = ex.getIn().getBody(Data.class); lastId = data.getId(); NewData newData = (NewData) convertData(data); ex.getMessage().setBody(newData); }).to(';jpa://NewData';) </code> Now I want to save <code>startId</code> after the current polling is over. To do so, I overrode the <code>PollingConsumerPollStrategy</code> with my custom one where I want to access <code>lastId</code> inside the <code>commit</code> method (which gets executed exactly when I want it to, after the current polling is complete). However, I can't access the route there. I tried via the route ID: <code> @Override public void commit(Consumer consumer, Endpoint endpoint, int polledMessages) { var route = (MyRoute) endpoint.getCamelContext().getRoute(';dataRoute';); var lastId = route.getLastId(); log.debug(';LastID: {}';, lastId); } </code> However I'm getting a class cast exception: <code>DefaultRoute</code> to <code>MyRoute</code>. Is it something about handing the ID to my route? | I would do it a bit differently. Instead of using RouteBuilder instance vars for storing <code>startId</code> and <code>lastId</code>, you may also put these values as GlobalOptions (which is basically a map of key-value pairs) of current CamelContext. This way, you can easily obtain their value using: <code>public void commit(Consumer consumer, Endpoint endpoint, int polledMessages) { String lastId = endpoint.getCamelContext().getGlobalOption(';lastId';); } </code> It is also (theoretically) a better implementation because it also supports potential concurrent executions, as the id are shared for all instances running in the context. |

apache-camel | I am trying to understand the cardinality between Messages and Exchanges. In the following route, by the time one message makes it to the final log how many Exchanges are created? <code>from(';timer:one-second-timer';) .bean(messageTransformer, ';transformMessage';) .to(';log:logging-end-point';); </code> Since a Message can hold only one ';in'; message, I imagine there will be one Message for each end-point the message hops on. Is this true? | You can consider an <code>Exchange</code> as being the envelope containing the <code>Message</code> + some meta-data (the <code>Properties</code>), allowing this message to be transported between endpoints. The javadoc says:An Exchange is the message container holding the information during the entire routing of a Message received by a Consumer.So, in your example, if the timer is fired 10 times, this will result in 10 distinct exchanges of one message. |

apache-camel | I have a route Producer ->; Split ->; Processor and in the processor, I am trying to find out if the current exchange being processed is the last one to get split. According to the camel split docs, three properties are put into every camel exchange that has been split. CamelSplitIndex, CamelSplitSize and CamelSplitComplete. When using camel 3.0.0-RC3, I am able to see these properties being populated and available in the processor class. But when using version 3.11.1 or 3.17.0, I do not see these values being populated in the exchange. Am I missing something here or is this a camel bug.

The method getProperties() now only returns user properties. To include internal properties as well, then use getAllProperties(). The other APIs such as getProperty(String) works the same way as before, being able to lookup a property regardless if its internal or custom.You should be able to access the split related properties:Either switching to use <code>Exchange#getAllProperties</code>: <code> exchange.getAllProperties().get(';CamelSplitIndex';); </code>Or better use the safer <code>Exchange#getProperty(ExchangePropertyKey)</code>: <code> exchange.getProperty(ExchangePropertyKey.SPLIT_INDEX); </code> |
apache-camel | I have a situation where I pull a file from a folder via a Camel SFTP route. There are 3 other Camel routes which need to process the same file which I am pulling... the other routes monitor the same SFTP server. Currently, we are thinking that we should make that file which I pull, available to the 3 other routes by placing a copy of the file in 3 separate folders where each folder is monitored by one of those other 3 routes... one unique folder for each of the 3 routes. When the other routes detect the presence of the file I would copy, they would fire up and proceed as required. The first question is whether this is a reasonable means of handling the scenario I just described or whether there is a better way. Secondly, assuming the scenario is reasonable, the question is what is the best way to handle propagating the file I pull to 3 different folders on the same SFTP server. For what it's worth, we are using Spring XML DSL. | I think you should decouple the scanning of the files from the processing of the files. In particular, there is maybe no real need to read a same file multiple times on the SFTP server, but only to process its content multiple times. This could end up to something like: <code>from(';sftp://server/folder1';) .to(';direct:processing1';);from(';sftp://server/folder2';) .to(';direct:processing2';);from(';sftp://server/folder3';) .to(';direct:processing3';);from(';sftp://server/toplevel';) .multicast().parallelProcessing() .to(';direct:processing1';) .to(';direct:processing2';) .to(';direct:processing3';) .end(); </code> |

apache-camel | I am trying to get tweets from my Twitter timeline with <code>ConsumerTemplate</code> (Camel) in a Quarkus app. I don't understand how it should be done correctly while using rate limits (my free account has rate 15 polls in 5 min). The Camel setup has property count which I set to <code>10</code>, and expect to get <code>10</code> new tweets in one poll, but the problem is that template offers only one tweet per Camel request: <code>for (int i = 0; i < 15; i++) { // I would expect here List or stream, but I can get only single `Status` final Status tweets = consumerTemplate.receiveBodyNoWait(String.format(';twitter-timeline://home?sinceId=%s&;count=10';, sinceId), Status.class); // just to show that I change that property if (nonNull(tweets)) { sinceId = tweets.getId(); }} </code> So my question is why I get only one tweet per poll even if count is set (a value more than <code>1</code>). Is there any better way or running that template, or something I can use instead while respecting downstream Twitter rate limits? | The <code>ConsumerTemplate</code> is based on a <code>PollingConsumer</code> under the hood, which as the name implies, pulls <code>Exchage</code>s one at a time hence why you are receiving only 1 <code>Status</code> (== 1 <code>Exchange</code>) even while setting a <code>count</code> endpoint option. It is almost hard (and error-prone) to implement tweets (or other <code>Exchange</code>s) consumption the right way. Indeed this is already offered out-of-the-box with the Apache Camel Twitter Component consumer. Here down a sample of a route to consume user public activity (timeline) using the twitter-timeline component: <code><routes xmlns:xsi=';http://www.w3.org/2001/XMLSchema-instance'; xmlns=';http://camel.apache.org/schema/spring'; xsi:schemaLocation='; http://camel.apache.org/schema/spring https://camel.apache.org/schema/spring/camel-spring.xsd';>; <route id=';twitter-timeline'; autoStartup=';true';>; <from uri=';twitter-timeline:USER?user=some-user&;amp;consumerKey=your-app-key&;amp;consumerSecret=your-app-key-secret&;amp;accessToken=your-app-access-token&;amp;accessTokenSecret=your-app-access-token-secret';/>; <log message=';${body}';/>; </route>;</routes>; </code> This will leverage the default polling configured delays which you can tweak based on your preferences to address any rate-limits. In your case for example, to respect 15 requests per 5 mins, you can set the consumer to poll each 20 seconds for one page: <code><from uri=';twitter-timeline:USER?user=some-user&;amp;count=100&;amp;numberOfPage=1&;amp;delay=20000';/>; </code> |

apache-camel | I am trying to use Apache Camel File-Watch feature. However I notice all example are used along with Spring. Is there anyway to make use of this feature without Spring ?

It is not tied to Spring in any way at its core and has different deployment / integration models out of which is Spring / Spring Boot for the sake of easing its adoption and configuration for Spring framework users. Out of the runtime contexts, you can use for example Camel Main component to run your application having a File Watch component setup to watch the <code>/tmp/</code> directory change events: The main application would look like the following: <code>public class FileWatchApplication { private FileWatchApplication() { } public static void main(String[] args) throws Exception { // use Camels Main class Main main = new Main(FileWatchApplication.class); // now keep the application running until the JVM is terminated (ctrl + c or sigterm) main.run(args); } } </code> A simple <code>RouteBuilder</code> setting up your File Watch component would look like the following (note that it must be within the same (or child) package of the <code>FileWatchApplication</code> class): <code>public class FileWatchRouteBuilder extends RouteBuilder { @Override public void configure() throws Exception { // snippet configuration from the official documentation from(';file-watch:///tmp/';) .log(';File event: ${header.CamelFileEventType} occurred on file ${header.CamelFileName} at ${header.CamelFileLastModified}';); } } </code> |

The problem is that I now receive this error. <code>Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property 'startDelayedSeconds' of bean class [org.apache.camel.component.quartz.QuartzComponent]: Bean property 'startDelayedSeconds' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter? </code> I looked and saw that the the StartDelayedSeconds method is not part of quartz as it was with quartz2. Does this mean that they are really not the same? If this is the case, then why is the newest version of quartz2 so far behind the newest version of quartz. Is there some sort of workaround that I could do, or some part of quartz that I should use? | From the Came 3 migration guide:The quartz2 component has been renamed to quartz, and it’s corresponding component package from org.apache.camel.component.quartz2 to org.apache.camel.component.quartz. The supported scheme is now quartz. Source: https://camel.apache.org/manual/camel-3-migration-guide.htmlWhen I run command <code>mvn dependency:tree</code> with project that contains camel-quartz dependency I get the following: <code>[INFO] +- org.apache.camel:camel-quartz:jar:3.4.4:compile [INFO] | +- org.quartz-scheduler:quartz:jar:2.3.2:compile [INFO] | | +- com.mchange:mchange-commons-java:jar:0.2.15:compile [INFO] | | \- com.zaxxer:HikariCP-java7:jar:2.4.13:compile [INFO] | \- com.mchange:c3p0:jar:0.9.5.5:compile </code> Based on that I would say its safe to assume that camel-quartz in camel 3.x uses quartz scheduler version 2.x. The option <code>StartDelayedSeconds</code> has likely been moved or changed during one of the major or minor version changes. A lot of components have gone through some changes to use more up to date libraries and to make them easier to use or just consistent with other components. [Edit] Regarding the StartDelayedSeconds option found this from one of the many Apache Camel upgrade guides.UPGRADING CAMEL 3.14 TO 3.15 Removed the option startDelaySeconds as this does not work correctly and causes problems if in use.

apache-camel | I have two routes: <code>.from(';A';) .to(';C';) .to(';B';);.from(';C';) *some processing logic* .to(';D';); </code> Is it possible to build the second route such that:when the message comes from the first route, some or all parts of the logic are ommited; when the message comes to the second route directly, the logic is used? | You can set exchange properties on route(s). Then you can evaluate the values inside filter or choice to branch or alter the routing logic. I would advice against anything more complex than this to avoid unnecessary coupling between routes.

apache-camel | Into a camel processor, I have set two static vars with property names: <code> public static final String CI_PROPERTY = ';ci';; public static final String IS_PDF_PROPERTY = ';isPdf';; </code> and I assign like: <code> exchange.setProperty(CI_PROPERTY, documentProperties.get(MAP_PARAMETER_ATTACHMENT_URI)); exchange.setProperty(IS_PDF_PROPERTY, documentProperties.get(MAP_PARAMETER_IS_PDF)); </code> These names should be used in other processors to retrieve properties. The question is: other processors have access to these names? Or I should move them to another class? In case, where? | Yes, you can do that as you can be seen below: <code>import org.apache.camel.Exchange; import org.apache.camel.Processor;public class FooProcessor implements Processor { public static final String FOO_PROPERTY = ';FOO';; @Override public void process(Exchange exchange) throws Exception { exchange.setProperty(FOO_PROPERTY, ';This is a Foo property.';); } } </code> <code>import org.apache.camel.Exchange; import org.apache.camel.Processor;public class BarProcessor implements Processor { @Override public void process(Exchange exchange) throws Exception { exchange.getMessage().setBody(exchange.getProperty(FooProcessor.FOO_PROPERTY, String.class)); } } </code> <code>from(';direct:mainRoute';) .routeId(';MainRoute';) .log(';MainRoute BEGINS: BODY: ${body}';) .process(new FooProcessor()) .process(new BarProcessor()) .log(';MainRoute ENDS: BODY: ${body}';) .end() ; </code> When the route above will be run the following is logged as expected: <code>MainRoute BEGINS: BODY: MainRoute ENDS: BODY: This is a Foo property. </code> However I don't think processors should have compile time (nor runtime) dependencies to other processors. As usual refactor the common parts to another class which is used by the processors. |
apache-camel | I'm running a Camel route that reads a flag record from database. If flag is NOT there then insert it and perform some additional stuff.

I'm using spring XML DSL and this is the route: <code> <from uri=';file:/D:/LOCAL/?include=(?i).*.zip&;amp;moveFailed=ErrorFiles&;amp;move=D:/LOCAL/WRK/';/>; <!--Catch a zip file as trigger for route-->; <to uri=';sql:SELECT LOAD_DATE FROM IMPORT_CUSTOMER_CTRL WHERE LOAD_DATE = CURRENT_DATE?datasource=#customerDS&;amp;routeEmptyResultSet=true&;amp;outputType=SelectOne';/>; <!-- Read a flag record from db -->; <log message=';Query result: ${body}'; loggingLevel=';INFO';/>; <choice>; <when>; <simple>;${body)} == null</simple>; <!--IF RESULTSET IS EMPTY THEN DO SOMETHING.

I know cause I always get the ';Flag record already exists..'; message in log. What's the correct way to evaluate whether the resultset is empty? | would you post your comment as answer so I can mark it as accepted answerAs explained here above, a generic solution, working whatever the output type (I mean a list as well as a single tuple) is to analyse the various ';meta-data'; published as headers by Camel : https://camel.apache.org/components/3.17.x/sql-component.html#_message_headers You should especially have a look at <code>CamelSqlRowCount</code> which, as its name indicates it, will give you information about the number of records returned by your SQL query. |

apache-camel | I am new to Apache Camel and I would like to ask a few things. Basically, I want to call the API based on the resource ID list I have and combine all the responses from the API into one message. I have already tried AggregationStrategy, but it doesn't seem to be working. The message body always returns the last response from API and it doesn't keep the old list.

apache-camel | I have an Apache Camel application, which uses a Choice with a Predicate. How can I test the predicate without an integration test? Code <code>@SpringBootApplication public class TestApplication { public static void main(String[] args) { SpringApplication.run(TestApplication.class, args); } @Bean public EndpointRouteBuilder route() { return new EndpointRouteBuilder() { @Override public void configure() throws Exception { from(file(';d:/tmp/camel/';)) .choice() .when(jsonpath(';$[?(@.status == 0)]';)) .log(';ok';) .otherwise() .log(';not ok';); } }; } } </code> ResearchI read Test JUnit5, but it looks like an integration test. However, I don't want to test a full route.I read Test Spring JUnit5, but it is an integration test. Question How can I extract the predicate <code>jsonpath(';$[?(@.status == 0)]';)</code> and test it isolated in an unit test with JUnit 5? | Might be hard to accomplish this without a CamelContext. I'd probably approach this with Camel's excellent mocking and stubbing utilities. But if you really just want to isolate the jsonpath expression, you could try something like this: <code>JsonPathExpression exp = new JsonPathExpression(';$[?(@.status == 0)]';); Exchange exchange = new DefaultExchange(context); final Predicate predicate = exp.createPredicate(context); exchange.getIn().setBody(';{ \';status\';: 0 }';); final boolean matches = predicate.matches(exchange); assertTrue(matches); </code> Note that you'll still need a CamelContext for this. Typically you'd get it by having the test class extend CamelTestSupport, or if you're in a spring environment, spring can autowire it: <code>@Autowired CamelContext camelContext;</code> Edit: If you just want to test the JsonPath expression outside of Camel: <code>String jsonPath = ';$[?(@.status == 0)]';; String json = ';{ \';status\';: 0 }';;DocumentContext jsonContext = JsonPath.parse(json); JSONArray result = jsonContext.read(jsonPath); assertEquals(1, result.size()); </code> |
apache-camel | Current behaviour: When I'm running a Quarkus App with Camel it automatically starts all the RouteBuilder Extensions as Routes. What I want to achieve: On startup only the Routes that I configured are started. What I tried:With the following snippet it's possible to explicitly start the CamelMainApplication but I dont know how to get control over e.g. the CamelContext at this point where I would be able to configure my routes.<code>@QuarkusMain public class Main { public static void main(String[] args) throws Exception { Quarkus.run(CamelMainApplication.class, args); } } </code>On the Route I can use .noAutoStartup() to disable the route on startup. But this means that it's not the default for all routes to be disabled at first and second I don't know where to activate them as I don't know where in a Quarkus App I can get a hand on the Camel Context to activate the route.With the following in my application.yml I can disable the automatic route discovery but then the remaining question is how I can manually start the route, e.g. in my QuarkusMain class. <code>quarkus: camel: routes-discovery: enabled: false </code> | I think it is best way. Quarkus has properties for include and exclude route as pattern. this properties is List You can add one to N <code>quarkus.camel.routes-discovery.exclude-patterns=tes.Comp,tes.package.MyRoute quarkus.camel.routes-discovery.include-patterns=test.mypackage.XX </code> |
apache-camel | I have seen a bunch of explaination, even on this site, about the error above... but no one was sufficiently clear about this two points:Why appears this error? How can I correct it exactly? What must I change in Camel/Spring boot project to make things work (what files, what configurations, what import of xsd? I must change POM? Where? Etc) | The Apache Camel metamodel has been modified. You need to adapt the model or to point to the version of the xsd matching the version of your model. if you are migrating from a 2.x to 3.x version, see https://camel.apache.org/manual/camel-3-migration-guide.html#_setheader_and_setproperty_in_xml_dsl So migrate <code><setHeader headerName=';foo';>;<simple>;Hello ${body}</simple>;</setHeader>; </code> To <code><setHeader name=';foo';>;<simple>;Hello ${body}</simple>;</setHeader>; </code> To adapt to the correct version of xsd, you need to change the xsi:schemaLocation and point to a specific version instead of the ';generic one';. So replace something like https://camel.apache.org/schema/spring/camel-spring.xsd by https://camel.apache.org/schema/spring/camel-spring-2.25.4.xsd or https://camel.apache.org/schema/spring/camel-spring-3.17.0.xsd |

apache-camel | Is it possible to set a response body to an object and pass in a camel header property. I can achieve this in a processor but I'd rather do it in line of the route. <code>.setBody(constant( new Foo() .withOne(';HelloWorld';) .withTwo(simple(';Header property is ${header.uniqueProperty}';).toString()) )) </code> With the above code I get a response of: <code><foo>; <one>;HelloWorld</one>; <two>;Header property is ${header.uniqueProperty}</two>; </foo>; </code> Here is my POJO <code>@XmlRootElement @XmlAccessorType(XmlAccessType.FIELD) public class Foo { private String one; private String two; public String getOne() { return one; } public void setOne(final String one) { this.one = one; } public String getTwo() { return two; } public void setTwo(final String two) { this.two = two; } public Foo withOne(final String one) { setOne(one); return this; } public Foo withTwo(final String two) { setTwo(two); return this; } } </code> | <code>constant()</code> probably won't work for you, since you probably want this dynamically evaluated for every exchange that passes through. Since you need to set the body to a newly instantiated object, you need a mechanism that's capable of this. You mentioned you want to avoid a processor, but I'd like to point out how simple this could be done in the route: <code>.setBody(exchange ->; new Foo() .withOne(';HelloWorld';) .withTwo(simple(';Header property is '; + exchange.getIn().getHeader(';uniqueProperty';))) ) </code> Edit: Actually this is not a processor. We're just passing a lambda (<code>Function</code>) to <code>setBody()</code>. If you're in a Spring environment, you could use spring expression language: <code>.setBody().spel(';#{new Foo()'; + ';.withOne('HelloWorld')'; + ';.withTwo(simple('Header property is ' + request.headers.uniqueProperty))}';); </code> |
apache-camel | I am trying to compound conditions with the PredicateBuilder and saving it to the header to access the predicate from the when() function. At the beginning I set the body to <code>Hello World</code>. Also the body is not null or not equal to <code>AUTHENTICATE failed</code> but I getting into the when block and <code>process_no_mail_or_failed</code> is being logged. I do not understand what I am doing wrong. How can I compound predicates in Apache Camel and use them in the when() function? In case I have to check the body at some step. Therefore I did it in the way. I apreciate any help! Apache Camel route: <code>import org.apache.camel.Exchange; import org.apache.camel.Message; import org.apache.camel.Predicate; import org.apache.camel.Processor; import org.apache.camel.builder.PredicateBuilder; import org.apache.camel.builder.RouteBuilder; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.stereotype.Component;@Component public class TestRoute extends RouteBuilder { static final Logger LOGGER = LoggerFactory.getLogger(EmailPollingRoute.class); static final String AUTHENTICATE_FAILED = ';AUTHENTICATE failed.';; @Override public void configure() throws Exception { from(';quartz://emailTimer?cron=0/30+*+*+*+*+?+*';) .log(';TestRoute - Before calling transform';) .process(new Processor() { @Override public void process(Exchange exchange) throws Exception { Message message = exchange.getIn(); message.setBody(';Hello World';); String body = message.getBody(String.class); LOGGER.info(';body: '; + body); Predicate p1 = body().isNull(); Predicate p2 = body().isEqualTo(AUTHENTICATE_FAILED); Predicate predicate_result12 = PredicateBuilder.or(p1, p2); message.setHeader(';process_no_mail_or_failed';, predicate_result12); } }) .choice() .when(header(';process_no_mail_or_failed';).convertTo(Predicate.class)) //.when(simple(';${body} == null || ${body} == 'AUTHENTICATE failed.'';)) //This works for me. I am getting into the otherwise block .log(';when: ${body}';) .otherwise() .log(';otherwise: ${body}';); } } </code> | Predicates have matches method which you can use to evaluate the predicate with If you want to get the result for Predicate you can use the matches-method to evaluate the predicate. <code>from(';direct:example';) .routeId(';example';) .process(exchange ->; { Predicate bodyNotNullOrEmpty = PredicateBuilder.and( body().isNotEqualTo(null), body().isNotEqualTo(';';) ); Boolean result = bodyNotNullOrEmpty.matches(exchange); exchange.getMessage().setHeader(';bodyNotNullOrEmpty';, result); }) .choice().when(header(';bodyNotNullOrEmpty';)) .log(';body: ${body}';) .otherwise() .log(';Body is null or empty';) .end() .to(';mock:result';); </code> You could also just import static methods from the Predicate builder and use them within choice without having to store the result to exchange property. This trick of importing the static methods from Predicate builder can be easy to miss due to it being only mentioned in negate predicates section of the documentation. <code>import static org.apache.camel.builder.PredicateBuilder.not; import static org.apache.camel.builder.PredicateBuilder.and;...from(';direct:example';) .routeId(';example';) .choice() .when(and(body().isNotNull(), body().isNotEqualTo(';';))) .log(';body: ${body}';) .otherwise() .log(';Body is null or empty';) .end() .to(';mock:result';); </code> |
apache-camel | I read in the Camel documentation that we can use looping with a <code>doWhile</code> construct. But it is not clear to me: does the Camel's <code>doWhile</code> behaves like a classic <code>do-while</code> (executing at least once without condition), or it is more like the <code>while</code> construct (executing only if condition is true)? | I have tested, and it seems equivalent to the <code>while</code> construct. |
apache-camel | I am using Apache Camel DSL route and want to check if the body is not <code>null</code> and body does not contains substring like <code>authenticate failed</code>. In java something like: <code> if(body != null &;&; !body.contains(';authenticate failed';)) { //Do something. } </code> Apache Camel DSL: <code> .choice() .when(body().contains(';authenticate failed';)) .log(';after choice body().contains('authenticate failed') body: ${body}';) .when(body().isNotNull()) //Here I want to add the addiontional condition to this when `body not contains authenticate failed`. </code> How can I write a condition like this? predicates objects in the process method and write tin my case? | You can use PredicateBuilder to create pretty composite predicates. Here's example how to do simple Body is not null or empty check with PredicateBuilder. <code>package com.example;import org.apache.camel.Predicate; import org.apache.camel.RoutesBuilder; import org.apache.camel.builder.PredicateBuilder; import org.apache.camel.builder.RouteBuilder; import org.apache.camel.component.mock.MockEndpoint; import org.apache.camel.test.junit4.CamelTestSupport; import org.junit.Test;public class ExampleTests extends CamelTestSupport { @Test public void testValidBody() throws Exception { MockEndpoint resultMockEndpoint = getMockEndpoint(';mock:notNull';); resultMockEndpoint.expectedMessageCount(1); template.sendBody(';direct:predicateExample';, ';Hello world!';); resultMockEndpoint.assertIsSatisfied(); } @Test public void testEmptyBody() throws Exception { MockEndpoint resultMockEndpoint = getMockEndpoint(';mock:nullOrEmpty';); resultMockEndpoint.expectedMessageCount(1); template.sendBody(';direct:predicateExample';, null); resultMockEndpoint.assertIsSatisfied(); } @Test public void testNullBody() throws Exception { MockEndpoint resultMockEndpoint = getMockEndpoint(';mock:nullOrEmpty';); resultMockEndpoint.expectedMessageCount(1); template.sendBody(';direct:predicateExample';, null); resultMockEndpoint.assertIsSatisfied(); } @Override protected RoutesBuilder createRouteBuilder() throws Exception { return new RouteBuilder() { @Override public void configure() throws Exception { Predicate bodyNotNullOrEmpty = PredicateBuilder.and( body().isNotNull(), body().isNotEqualTo(';';) ); from(';direct:predicateExample';) .routeId(';predicateExample';) .choice().when(bodyNotNullOrEmpty) .log(';Received body: ${body}';) .to(';mock:notNull';) .otherwise() .log(';Body was null or empty!';) .to(';mock:nullOrEmpty';) .end() .log(';done';); } }; } } </code> Not and Or can take lists of predicates as arguments or even other composite predicates which allows one to make some fairly complex composite predicates. However when using PredicateBuilder starts to get overly verbose it's good to just use processor or bean instead to abstract away some of the complexity. |

Mainly because the transaction scope is difficult to figure out in camel. the transaction error handler, taking the lead once redelevery policy are exhausted, and somehow seems to happen within onException without clear demarcation : for example : <code>onException(IOException) // the ';following'; (whatever holds behind the scene) happens inside transaction .maximumRedeliveries(3) .retryAttemptedLogLevel(WARN) .retriesExhaustedLogLevel(ERROR) .onExceptionOccurred(exceptionOccurredProcessor) // then on redelivery exhaustion the transaction is rolledback // the following happens after rollback .log(...) .to(...) </code> We had to make database operation support retries (due to some autonomous transactions), but this is simplier than structuring for camel transacted route. Furthermore, it just happens that transacted route main purpose is the rollback of the message in the jms as well, but we don't want this because we handle errors with DLQs. with_spring_transaction |

apache-camel | I'm using Apache Camel with the aws2-s3 module to access an S3 bucket. I'm using endpoint-dsl to program my routes. I can connect to and read from the bucket, but I get Access Denied when trying to upload. I need to enable SSE-S3. I've seen other posts that state that the x-amz-server-side-encryption header needs to be set, but how do I do that? In the documentation for the aws-s3 component, it states: <code>CamelAwsS3ServerSideEncryption</code> Sets the server-side encryption algorithm when encrypting the object using AWS-managed keys. For example use AES256. I can't find any other reference to AWS-managed keys in the documentation unless it's referring to KMS or customer keys. I've tried <code>.setHeader(AWS2S3Constants.SERVER_SIDE_ENCRYPTION, constant(';AES256';))</code> which doesn't seem to actually enable SSE-S3. I've also tried setting the header in these other ways: <code>Map<String,Object>; headers = new HashMap<>;(); headers.put(';x-amz-server-side-encryption';, ';AES256';); ... .process(exchange ->; { exchange.getIn().setHeader(';x-amz-server-side-encryption';, ';AES256';); }) .setHeader(AWS2S3Constants.SERVER_SIDE_ENCRYPTION, constant(';AES256';)) .setHeader(AWS2S3Constants.METADATA, () ->; headers) .setHeader(';CamelAwsS3Headers';, () ->; headers) </code> | This should be resolved through this: https://issues.apache.org/jira/browse/CAMEL-18064 Available in the upcoming release 3.17.0. I fixed it this morning. |
