问题 I am doing a simple unit test with camel. All I want to do is to read a json from a file (under resources), send it to a java class for validation - this is the route that I am trying to test. Whatever I do, the template (which I use to sendBody(json) is always null. Here is my code public class RouteTests extends CamelTestSupport { @EndpointInject(uri = "mock:result") protected MockEndpoint resultEndpoint; @Produce(uri = "direct:start") protected ProducerTemplate template; @Autowired

问题 We use Java DSL to configure our routes. All configurations for routes are in a db table and can be configured via a GUI. How is it possible to ensure that the camelContext starts up even if a route is misconfigured (e.g. .to(invalidurl or typo) in a route or simply a bug in a route)? Is there a possibilty to validate the routes before starting or maybe better some parameters/options which can be set on the context itself? 回答1: You can configure the routes with .autoStartup(false), and then

问题 I have a code like - // use streaming to increase index throughput .setHeader(SolrConstants.OPERATION, constant(SolrConstants.OPERATION_INSERT_STREAMING)) // define solr endpoint and options .to("solr://" + getSolrEndPoint() + "?defaultMaxConnectionsPerHost=500&streamingThreadCount=500&maxRetries=3") .log(LoggingLevel.INFO, "Successfully indexed document id [" +header(BatchHeaders.DOCUMENT_ID) +"]") // end this route .end(); But what I m getting in the log is - severity="INFO " thread="Camel

问题 I'm trying to upload a jpg file to AWS S3 bucket with Camel's aws-s3 producer. Can I make this work with this approach and if yes how? Now I'm only getting an IOException and can't figure out what would be the next step. I know I could implement the upload using TransferManager from the aws-sdk but now I'm only interested in Camel's aws-s3 endpoint. Here is my route with Camel 2.15.3: public void configure() { from("file://src/data?fileName=file.jpg&noop=true&delay=15m") .setHeader

问题 My experimental application is quite simple, trying what can be done with Actors and Akka. After JVM start, it creates actor system with couple of plain actors, JMS consumer (akka.camel.Consumer) and JMS producer (akka.camel.Producer). It sends couple of messages between actors and also JMS producer -> JMS server -> JMS consumer. It basically talks to itself via JMS service. From time to time I was experiencing weird behaviour: it seemed that from time to time, first of messages which where

问题 I have a problem. The apache camel documentation states that for the camel-restlet component (starting from 2.10 version) is possible to define the max number of threads that will service requests (http://camel.apache.org/restlet.html). How can i specify this parameter? This is the route that I made from( "restlet:http://localhost:" + config.getEmergencyRESTPort() + "?restletMethods=post,get&restletUriPatterns=#emergencyUriTemplates&maxThreads=64").process( new EmergencyServerProcessor(config

问题 I'm new to apache-camel and know i met a problem. I want to use simple expressions in my uri definition, but i don't know how. For example: from("foo://bar").to("foo://bar?var=${header.varName}"); Is there a way to use such expressions? 回答1: Bernhard http://camel.apache.org/how-do-i-use-dynamic-uri-in-to.html Use the Recipient List EIP pattern, which allows you to compute the dynamic URI using an Expression.
