RabbitMq consumer error in spring-boot

[Namita Jaokar]

Hi ,

I am trying to implement rabbitmq producer-consumer using spring-boot in windows 10. 

My producer is able to send messages without any error in the application logs.

However, when I start my consumer application , I have observed below error logs before the consumer successfully consumes the message.

Below are the sample application logs:

2022-09-20 13:47:23.550 ERROR 2916 --- [ 127.0.0.1:5672] o.s.a.r.c.CachingConnectionFactory       : Shutdown Signal: channel error; protocol method: #method<channel.close>(reply-code=406, reply-text=PRECONDITION_FAILED - inequivalent arg 'durable' for queue 'rabbitmq.demo.queue' in vhost '/': received 'false' but current is 'true', class-id=50, method-id=10)
2022-09-20 13:47:28.554  INFO 2916 --- [           main] o.s.amqp.rabbit.core.RabbitAdmin         : Auto-declaring a non-durable, auto-delete, or exclusive Queue (rabbitmq.demo.queue) durable:false, auto-delete:false, exclusive:false. It will be redeclared if the broker stops and is restarted while the connection factory is alive, but all messages will be lost.

Can someone please help me understand what needs to be fixed in this case or do I need to ignore this kind of messages.

Please advise.

Thanks & Regards,

Namita

Hello Namita,

 

The error you are seeing is coming from your queue declarations. In at least one case, you have declared the queue rabbitmq.demo.queue with durable:false, but someone else has declared it first with durable:true. Ensure that all your queue declarations are consistent to avoid this error by changing all durable values to be the same.

 

Regards,

Brian
