Dynamic addition of queues to a rabbit listener at runtime

Question

I\'ve got a project where we are going to have hundreds (potentially thousands) of queues in rabbit and each of these queues will need to be consumed by a pool of consumers.

Answer 1

• Inject (@Autowired or otherwise) the RabbitListenerEndpointRegistry.

• Get a reference to the listener container (use the id attribute on the annotation to give it a known id) (registry.getListenerContainer(id)).

• Cast the container to an AbstractMessageListenerContainer and call addQueues() or addQueueNames().

Note that is more efficient to use a DirectMessageListenerContainer when adding queues dynamically; with a SimpleMessageListenerContainer the consumer(s) are stopped and restarted. With the direct container, each queue gets its own consumer(s).

See Choosing a container.
