Spring JMS start listening to jms queues on request

问题

Spring provides @JMSListener annotation to listen to messages from a particular queue. There is also an alternative to implement JmsListenerConfigurer and register a MessageListener.

In both the cases, the name of the queue has to be known at the time when the application starts, either by hardcoding in the code or via properties.

Is there a way to listen to a queue whose name is known to the application much later after it started?

回答1:

This should work.

1. Configure the @JmsListener with a dummy queue name and an id.
2. Configure the listener container factory with autoStartup false.
3. When you are ready, get a reference to the listener container using it's id from the JmsListenerEndpointRegistry (auto wire the registry into your app and call getListenerContainer(id)).
4. Cast the container to an AbstractMessageListenerContainer and call setDestinationName (or setDestination) with the desired queue.
5. start() it.
