spring-jms

问题 We just upgraded to Spring 4 and JMS 2.0. We are using a CachingConnectionFactory and a JmsTemplate to publish messages and noticed that when publishing to a destination, the first attempt works and then further attempts to publish to the same destination cause the following exception: Caused by: javax.jms.IllegalStateException: The producer is closed Everything worked fine with Spring 3.2 and JMS 1.1 so I did some digging to see what the problem was and it seems the issue is in the

问题 There is a route which is consuming messages from a jms queue and after doing some processing sending a request to unreliable web service(Which can be down at times). So in case of service is down then i need to stop consuming from queue for some time. I tried to use ThrottlingExceptionRoutePolicy . It will stop route as per configuration but issue is for the current message which gets the error as message is getting moved to dead letter queue. I've gone through the code of

问题 We have an application using Spring Boot and its JMS facility. At runtime, we have different producers that jump online and tell our application the name of the topic or queue to listen to. Right now, we have: @JmsListener(destination = "helloworld.q") public void receive(String message) { LOGGER.info("received message='{}'", message); } which works when we send a message to the helloworld.q topic. The problem is, we won't know what the name of the topic will be until runtime, and JmsListener

问题 We are trying to connect to IBMMQ using CCDT file and JMS configuration. We are able to connect to it but we have an issue here: since we are using spring to set connection factory with CCDT file, this is initialized once at the start of the application, but unfortunately it picks only one queue manager at a time,i.e it sends all the messages to same queue manager and it does not load balance. Though i observed, if i manually set the CCDT file before every request then its able to load

问题 I have two Spring Boot applications running on one server. Both use embedded ActiveMQ JMS. I want to have separate JMS instance for each application. How could I set the port for each of them? Is there any property like spring.activemq.port ? When I run second application I get the following expected error: Failed to start JMX connector Cannot bind to URL [rmi://localhost:1099/jmxrmi]: javax.naming.NameAlreadyBoundException: jmxrmi [Root exception is java.rmi.AlreadyBoundException: jmxrmi].

问题 I want to receive chunk of messages from Queue within some timeLimit(Ex : 300 millisec after receiving the 1st message) using DefaultMessageListenerConatiner Of Spring (By overriding doReceiveAndExecute) as mentioned in the link. I can group the messages of my batch size i.e 20 when the queue is having too many messages and I can receive less than 20 messages when there are very less messages in Queue. Issue : I see it takes too much time(sometimes 1 sec and sometime 2 secs and more) for

问题 When I use Spring to listen to JMS messages, I receievd the above error. I am wondering how to add an Errorhandler into the JMS listener? 回答1: There is a property on AbstractMessageListenerContainer: <bean id="listener" class="org.springframework.jms.listener.DefaultMessageListenerContainer"> <property name="errorHandler" ref="someHandler"/> <property name="destinationName" value="someQueue"/> <property name="connectionFactory" ref="connectionFactory"/> </bean> Where someHandler is a bean

问题 I was reading spring documentation on DefaultMessageListenerContainer It says "Note: Don't use Spring's CachingConnectionFactory in combination with dynamic scaling. Ideally, don't use it with a message listener container at all, since it is generally preferable to let the listener container itself handle appropriate caching within its lifecycle. Also, stopping and restarting a listener container will only work with an independent, locally cached Connection - not with an externally cached one
