我有一个被声明为会话范围的 bean。我必须在我的配置中启用 aop 才能在其他 bean 中使用它（默认为单例）。

confi

        <aop:scoped-proxy/>
    </bean>

当我从 Eclipse 启动它时，在我的 Windows 台式计算机上，它运行得很好，正如它所声明的那样。但是，当我在我的测试 Linux 环境中发布它时，它会以某种方式忽略 aop 的事情，并引发错误

linux环境下的异常

11:09:24,928 ERROR {localhost-startStop-1} [org.springframework.web.servlet.FrameworkServlet:initServletBean] Context initialization failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'scopedTarget.localeResolver': Scope 'session' is not active for the current thread; consider defining a scoped proxy for this bean if you intend to refer to it from a singleton; nested exception is 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.

日志文件中没有其他错误。不在网络应用程序日志中，也不在 catalina.out 中。我在tomcat 7.0.42和“CentOS release 6.5”上使用spring 3.2.4。

仔细阅读这些错误消息，总是包含失败的原因。

在这种情况下：

Scope 'session' is not active for the current thread

这意味着当请求 bean 时您没有活动的 HTTP 会话。
