问题 I am trying a very simple route with Spring Boot 1.5.2.RELEASE + Camel (Spring Boot Starter) + ActiveMQ, which is to read from a particular queue and then log it. However, it looks like it is not picking up my spring.activemq configuration for URL as I see in the log it is trying to connect to a different url and it continues to connect it and the my spring boot app never starts. The questions are based on my configuration that I am providing below how can I do the below: Fix the

问题 I am currently using a HTTP method for invoking some URL which will create a JIRA issue. Now I want to use Apache Camel, how can I use that? I need to invoke the following link through Camel: http://localhost:8080/rest/api/2/project/" + key + /components As I'm new to Camel, please suggest some solutions and examples too. Thanks 回答1: You could easily use the CXFRS Component; if you need to do it using the HTTP Component for some reason you could easily use that as well: <setHeader headerName=

问题 I need to log when a client is disconnected from Apache Camel connection. How can I detect a netty-tcp disconnection? from("{{uri.client.address}}") 回答1: Its a bit more complicated to log individual client disconnects but I will try to share what I had to do. You need to extend SimpleChannelInboundHandler with your own class and add the methods needed. For an example class see here: https://github.com/apache/camel/blob/master/components/camel-netty4/src/main/java/org/apache/camel/component

问题 I have to run a loop in the route. my route looks as <camel:loop> <camel:constant>${property.x}</camel:constant> </camel:loop> My processor looks as Date date = new Date(); this.LOGGER .info("\n****WELCOME TO THE REQUEST OF CHECK PROCESSOR**"); int y=4; Integer a=new Integer(y); exchange.setProperty(x,a); int k=(Integer) exchange.getProperty(x); this.LOGGER .info("\n***WELCOME TO THE REQUEST OF CHECK PROCESSOR ENDINGGGGGGGG***"+"a= "+a+" Y= "+y+" x= "+exchange.getProperty(x)+" k= "+k); while

问题 My objective is to use Camel along with its JMS component. The route config looks like below- from("jms:queue:test").to(mybean) I would like to add the option of kind 'parameter' and type 'object' to this route -for example the option 'jmsMessageType'. I saw some other posts that talks about using setProperty() on route definition but I could not find a definite answer. Options of type 'string' and numbers can be appended to the URI but not objects. JMS has an option of taskExecutor but how

问题 How do I configure the thread names created by Camel (version 2.8.1)? I need to have more concise thread names for logging purposes. The Camel documentation states that the default is: Camel (#camelId#) thread ##counter# - #name# Which results in names like: Camel (bundle_camel) thread #114 - JmsConsumer[SomeClassNameHere] But I want just: #camelId#-#counter# which would give me something like: bundle_camel-114 The documentation says how to change the thread name pattern by calling a manager

问题 I'm trying to use RabbitMQ with Camel. I am using Camel 2.14.1. I want to open an fanout exchange on RabbitMQ and then later bind queues to it. This seems to work fine. However, everytime I create an Exchange, it is automatically bound to queue with a system name (a number). Can't I avoid that? Here is a simple example which posts 100 messages to an Exchange. But they get delivered to an automatically created queue, I want to avoid this. @Override public void configure() throws Exception {
