I need to set the exchange and queue for RabbitMQ in my Spring Boot application, the thing is, The application only acts as a producer, but I need to define de queue as well in the service. steps that I did:

  1. set the @Input and @Output for my Queue and exchange.
  2. Define the bindings in application.yml (spring.cloud.stream.bindings and binders)
  3. develop the code to send the message using the @output method

When I run the application, the queue and exchange are in my RabbitMQ container, but when a message is received in the queue I have this error in my application:

Dispatcher has no subscribers for channel

Is it possible to set a queue using spring cloud stream without a listener? Only set the binding to set the queue in RabbitMQ

The spring cloud stream versions used is: 3.2.10 It's an old customer project.

Thanks in advance!

  • You must be using a very old version of spring-cloud-stream as @Input and @Output has log been deprecated and removed. Please read this section of the manual and feel free to follow up with more question docs.spring.io/spring-cloud-stream/reference/… Commented Oct 31, 2024 at 11:06
  • Thanks for your answer @OlegZhurakousky . Yes, I know, it's an old project that the customer has not updated yet. Intellij told me about this as well. Commented Oct 31, 2024 at 11:09
  • Well, it's no longer supported so I am not sure what else I can add as there is no code that corresponds to what you are asking about Commented Oct 31, 2024 at 11:11
  • Maybe if it's possible to set a queue in the service without listener. just to create the queue in RabbitMQ using the service?? Commented Oct 31, 2024 at 11:15

    This is not what spring-cloud-stream is designed for. Consider looking at spring-amqp project Commented Oct 31, 2024 at 11:46
