SimpleMessageListenerContainer 停止后未恢复

Question

当某个事件到来时，我使用 container.stop(); 停止我的 rabbitmq listner，在完成所需的工作后，我用 container.start() 重新启动它，但是当一个新事件到来时，我收到以下错误：

Exception in thread "SimpleAsyncTaskExecutor-1" 2016-04-22T16:20:53.646  WARN 15336 --- [cTaskExecutor-1] o.s.a.r.l.SimpleMessageListenerContainer : Consumer raised exception, processing can restart if the connection factory supports it

它实际上是一个无害（但可怕）的日志消息，但它是 fixed in 1.5.3。

如所述：

It's generally better to stop the container on a separate thread.

因为在侦听器退出之前容器无法完全停止。
