title: Multiple connections for RabbitMQ consumer
body: <p>I need to have my RabbitMQ consumer connect to multiple queues on different hosts. How can I have multiple connections getting messages sent to the same <code>onMessage</code> method? I tried the <code>@Configuration</code> style in <a href="http://docs.spring.io/spring-amqp/reference/html/amqp.html" rel="nofollow"><em>3.5.2 Asynchronous Consumer</em></a> with 2 <code>SimpleMessageListenerContainer</code> and <code>ConnectionFactory</code> and 1 <code>MessageListener</code> but only one of them picks up messages.</p>
  
  <p>Configuration code here: <a href="https://gist.github.com/mcamilleri/7212dd18d2010bf6695b" rel="nofollow">https://gist.github.com/mcamilleri/7212dd18d2010bf6695b</a> (I have a similar class called <code>ConsumerConfiguration2</code> that only uses a different hostname). <code>MessageListener</code> is in a separate class.</p>
