linux - Spring aop作用域代理在Linux安装上不起作用

Question

我有一个被声明为 session 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)。

配置

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:p="http://www.springframework.org/schema/p"

       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xsi:schemaLocation="http://www.springframework.org/schema/mvc

         http://www.springframework.org/schema/aop
         http://www.springframework.org/schema/aop/spring-aop.xsd
         ">
    ...
    <bean id="localeResolver" class="com.my.pack.MySessionLocaleResolver" scope="session">
        <property name="defaultLocale" value="en" />
        <aop:scoped-proxy/>
    </bean>

当我从 eclipse 启动它时，在我的 Windows 台式计算机上，它工作得很好，正如它所声明的那样。 但是，当我在我的测试 Linux 环境上发布它时，它确实忽略了 aop 的事情，并抛出一个错误

linux环境异常

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。也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 版本 6.5”上使用 spring 3.2.4。

仔细阅读这些错误消息，它们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 时您没有事件的 HTTP session 。
