Spring，jms 失去了上下文

Question

我正在编写使用一些工作人员的网络应用程序。我决定使用 JMS 在它们之间进行通信。我的问题是，当我将工作人员配置更改为 Java 时（当配置在 xml 中时，我无法运行 jar），当消息返回到 webapp 时我遇到问题：

2013-07-19 21:23:23.653   [org.springframework.jms.listener.DefaultMessageListenerContainer#4-3] WARN  o.s.j.l.DefaultMessageListenerContainer - Execution of JMS message listener failed, and no ErrorHandler has been set.
java.lang.IllegalStateException: No thread-bound request found: Are you referring to request attributes outside of an actual web request, or processing a request outside of the originally receiving thread? If you are actually operating within a web request and still receive this message, your code is probably running outside of DispatcherServlet/DispatcherPortlet: In this case, use RequestContextListener or RequestContextFilter to expose the current request.

我不知道如何在响应消息返回时接收上下文。

Answer 1

您正在尝试从 JMS 线程访问 Web 资源，但这是不允许的。

有问题的代码似乎在

CalculateResponseListener.getResultURL()

。

您需要重新构建应用程序以避免这种情况。
