Question

我有一个在Tomcat 6上运行的Spring Integration应用程序。它有一个message-driven-channel-adapter，它与远程Active MQ服务器通信。到目前为止，我能够完成我的工作。

然而，当我关闭Tomcat时，我在catalina日志中无休止地循环：

Exception in thread   "org.springframework.jms.listener.DefaultMessageListenerContainer#0-178" Exception in thread "org.springframework.jms.listener.DefaultMessageListenerContainer#0-179"

你们有什么想法吗？在关闭Tomcat之前，是否需要关闭或销毁Spring上下文？

感谢您的帮助

谢谢， Keth

好吧，看起来你是对的：

在关闭Tomcat之前，我是否需要关闭或销毁Spring上下文？

从Spring JSM源代码看，你的Tomcat早先关闭了它的 log4j.LogManager ，而不是Spring停止它的上下文。
