How to add multiple JMS MessageListners in a single MessageListenerContainer for Spring Java Config
java, jms, spring, spring-jms, xml
Solution
The namespace is just a convenience - each `<jms:listener/>` element gets its own `DMLC`; the outer (container) element is just a vehicle to supply common attributes.
Problem
I had the following xml code in my spring-config.xml ``` <jms:listener-container acknowledge="auto" connection-factory="cachedConnectionFactory" container-type="default" error-handler="consumerErrorHandler" concurrency="20-25"> <jms:listener destination="#{TaskFinished.destination}" method="onMessage" ref="taskFinished" /> </jms:listener-container> ``` Now, I was converting my spring xml configuration file to Java configuration. I translated it like ``` @Bean(name = "consumerJmsListenerContainer") public DefaultMessageListenerContainer consumerJmsListenerContainer() { DefaultMessageListenerContainer messageListenerContainer = new DefaultMessageListenerContainer(); messageListenerContainer .setConnectionFactory(cachingConnectionFactory()); messageListenerContainer.setConcurrency("20-25"); messageListenerContainer.setErrorHandler(new ConsumerErrorHandler()); messageListenerContainer .setSessionAcknowledgeMode(Session.AUTO_ACKNOWLEDGE); messageListenerContainer.setMessageListener(new TaskFinished()); return messageListenerContainer; } ``` What I need to know is, if there were more than one MessageListner in the Message Container like ``` <jms:listener-container acknowledge="auto" connection-factory="cachedConnectionFactory" container-type="default" error-handler="consumerErrorHandler" concurrency="20-25"> <jms:listener destination="#{questionGeneration.destination}" method="onMessage" ref="questionGeneration" /> <jms:listener destination="#{friendShipLogic.destination}" method="onMessage" ref="friendShipLogic" /> <jms:listener destination="#{postAvailabilityChecker.destination}" method="onMessage" ref="postAvailabilityChecker" /> <jms:listener destination="#{playOn.destination}" method="onMessage" ref="playOn" /> </jms:listener-container> ``` How could I supposed to convert this xml code into Java config?
