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并与远程 Active MQ 服务器通信。到目前为止，我能够完成我的工作。

但是，当我关闭 Tomcat 时，我在 catalina 日志中不断循环出现以下异常：

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

你们对此有什么想法吗？在关闭 Tomcat 之前是否需要关闭或销毁 Spring 上下文？

感谢你的帮助

谢谢，凯思

好吧，看起来你是对的：

在关闭 Tomcat 之前是否需要关闭或销毁 Spring 上下文？

从 Spring JSM 源代码来看，您的 Tomcat 似乎更早地关闭了它的log4j.LogManager，然后 Spring 停止了它的上下文。
