Spring AMQP + RabbitMQ 3.3.5 ACCESS_REFUSED - Login was refused using authentication mechanism PLAIN

Question

I am getting below exception

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

Configuration: RabbitMQ 3.3.5 on windows

On Config file in %APPDATA%\RabbitMQ\rabbit.config I have done below change as per https://www.rabbitmq.com/access-control.html

[{rabbit, [{loopback_users, []}]}].

I also tried creating a user/pwd - test/test doesn't seem to make it work.

Tried the Steps from this post.

Other Configuration Details are as below:

Tomcat hosted Spring Application Context:

<!-- Rabbit MQ configuration Start -->
    <!-- Connection Factory -->
    <rabbit:connection-factory id="rabbitConnFactory" virtual-host="/" username="guest" password="guest" port="5672"/>

    <!-- Spring AMQP Template -->
    <rabbit:template id="rabbitTemplate" connection-factory="rabbitConnFactory" routing-key="ecl.down.queue" queue="ecl.down.queue" />

    <!-- Spring AMQP Admin -->
    <rabbit:admin id="admin" connection-factory="rabbitConnFactory"/>

    <rabbit:queue id="ecl.down.queue" name="ecl.down.queue" />

    <rabbit:direct-exchange name="ecl.down.exchange">
        <rabbit:bindings>
            <rabbit:binding key="ecl.down.key" queue="ecl.down.queue"/>
        </rabbit:bindings>
    </rabbit:direct-exchange>

In my Controller Class

@Autowired
RmqMessageSender rmqMessageSender;

//Inside a method
rmqMessageSender.submitToECLDown(orderInSession.getOrderNo());

In My Message sender:

import org.springframework.amqp.core.AmqpTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

@Component("messageSender")
public class RmqMessageSender  {

    @Autowired
    AmqpTemplate                rabbitTemplate;

    public void submitToRMQ(String orderId){
        try{
            rabbitTemplate.convertAndSend("Hello World");
        } catch (Exception e){
            LOGGER.error(e.getMessage());
        }
    }       
}

Above exception Block gives below Exception

Answer 1

I am sure what Artem Bilan has explained here might be one of the reasons for this error:

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

but the solution for me was that I logged in to rabbitMQ admin page (http://localhost:15672/#/users) with the default user name and password which is guest/guest then added a new user and for that new user I enabled the permission to access it from virtual host and then used the new user name and password instead of default guest and that cleared the error.
