title: How to send basic.ack to Queue from message handler in SimpleMessageListenerContainer
body: <p>In RabbitMQ api, when <code>auto-ack</code> is set to false on a channel, we can use <code>channel.basicAck(...)</code> to send acknowledgement back to the queue.</p>
  
  <p>In Spring, I have a <code>SimpleMessageListenerContainer</code> where I set <code>AcknowledgeMode.MANUAL</code>. and handler (<code>SomeMessageHandler</code> that handles a String type) I set as the listener for the <code>MessageListenerAdapter</code>.  I can't find anywhere (any component) where I send the acknowledgement back to the queue. Is there a component I need to autowire to my handler to take care of this? Or what is the the correct way to handle this acknowledgement, when acknowledgment mode is set to manual?</p>
