Can I update AMQP settings in runtime?

Question

I have specific requirements: needed application that can change connection settings and listened queues in runtime.

I want to use Spring AMQP abstractions: CachingConnectionFactory, DirectMessageListenerContainer, RabbitTemplate, AsyncRabbitTemplate that application will update in runtime.

CachingConnectionFactory - update address, username and password. DirectMessageListenerContainer - update QueueNames. Last ones - will not updated, but affected by ConnectionFactory.

Is it correct way? Or I should use base implementation with consumers?

Answer 1

• stop all activity that uses the broker (listener containers, producers)
• cachingConnectionFactory.resetConnection()
• reconfigure connection factory
• add and remove queues to/from the containers
• start containers and producers
