I have spring boot rabbitmq application where i have to send an Employee object to queue. Then i have set up a listener application. Do some processing on employee object and put this object in call back queue.

For this, i have created below objects in my appication.

  1. Created ConnectionFactory.
  2. Created RabbitAdmin object using ConnectionFactory..
  3. Request Queue.
  4. Callback Queue.
  5. Direct Exchange.
  6. Request Queue Binding.
  7. Callback Queue Binding.
  8. MessageConverter.
  9. RabbitTemplate object.
  10. And finally object of SimpleMessageListenerContainer.

My Application files looks like below.

application.properties

spring.rabbitmq.host=localhost
spring.rabbitmq.port=5672
spring.rabbitmq.username=guest
spring.rabbitmq.password=guest
spring.rabbitmq.virtual-host=foo
emp.rabbitmq.directexchange=EMP_EXCHANGE1
emp.rabbitmq.requestqueue=EMP_QUEUE1
emp.rabbitmq.routingkey=EMP_ROUTING_KEY1

Can anybody help me resolving my issue? As per my understanding, when object of SimpleMessageListenerContainer is being created, callback queue is not created on rabbitmq server. I tried declaring queue using RabbitAdmin object, but then execution stops and nothing goes ahead. This problem was not there when i was declaring queue in default virtual host. But when i added virtual host foo all of it sudden stopped working. You can replicate this issue using above code. I have pasted all my code. Kindly let me know if anything else is to be posted.

Interesting point is even if i am getting this exceptions, my application is up and running. That means somehow my callback queue is created and object of SimpleMessageListenerContainer gets the queue. I read somewhere that, when queue is created, my SimpleMessageListenerContainer object will listen to it.

Please help me resolving this issue.

This problem was not there when i was declaring queue in default virtual host. But when i added virtual host foo all of it sudden stopped working.

Does the user that accesses the new virtual host have configure permissions? Configure permissions are required to declare queues.

A RabbitAdmin is required to declare the queues/bindings; the container only does a passive declaration to check the queue is present.

EDIT

container.start();

You must not start() the container within a bean definition. The application context will do that after the application context is completely built, if the container's autoStartUp is true (default).

It is clear from your logs that the container is starting too early - before the other beans (admin, queue etc) have been declared.
