RabbitMq ACCESS_REFUSED - Login was refused using authentication mechanism PLAIN. For details see the broker logfile.

[Sercan Noyan Germiyanoglu]

Hi,

I tried to implement an example of spring cloud example.

I run rabbitmq in docker through docker-compose.

rabbitmq:
   image: "rabbitmq:3-management"
   container_name: "rmq3"
   environment:
      RABBITMQ_DEFAULT_USER: "rabbitmq"
      RABBITMQ_DEFAULT_PASS: "123456"
   ports:
      - "5672:5672"
      - "15672:15672"

When I run report service, I got all these issues shown below.

org.springframework.context.ApplicationContextException: Failed to start bean 'org.springframework.amqp.rabbit.config.internalRabbitListenerEndpointRegistry'; nested exception is org.springframework.amqp.AmqpIllegalStateException: Fatal exception on listener startup

com.rabbitmq.client.AuthenticationFailureException: ACCESS_REFUSED - Login was refused using authentication mechanism PLAIN. For details see the broker logfile.

How can I fix it?

Here is my github project link : https://github.com/Rapter1990/SpringBootMicroservices

Hello,

Thanks for providing a very complete set of code and configuration to see this issue.

I forked the repository and simplified the docker compose file to only start RabbitMQ, so that I can confirm that the user and password are set correctly:

https://github.com/lukebakken/SpringBootMicroservices/blob/rabbitmq-only/docker-compose.yml

I then started it up, and exec'd into the running container to verify:

root@fdaeccf96a12:/# rabbitmqctl eval 'os:getenv("RABBITMQ_DEFAULT_USER").'
"rabbitmq"
root@fdaeccf96a12:/# rabbitmqctl eval 'os:getenv("RABBITMQ_DEFAULT_PASS").'
"123456"
root@fdaeccf96a12:/# rabbitmqctl authenticate_user rabbitmq 123456
Authenticating user "rabbitmq" ...
Success

So, it seems that your user and password are indeed created correctly. My guess now is that your Spring application is not being configured correctly.

I tried running docker compose up on the entire original project but ran into errors. Not sure why.

Thanks,

Luke

I see you are using config server; from my limited knowledge of that project, you appear to be setting things up correctly [1] [2].

I suggest you add some diagnostics to the report-service; something like

@Bean

ApplicationRunner runner(CachingConnectionFactory ccf) {

    return args -> {

        log.info(ccf.getRabbitConnectionFactory().getUsername());

        log.info(ccf.getRabbitConnectionFactory().getPassword());

     };

}

to make sure the config is being applied correctly; if it is not, I suggest you reach out the config server project.
