我现在正试图在我的Spring项目上启用AOP。我想在@RequestMapping完成后执行会话清理代码。这是我的applicationContext.xml，只需加载引用的资源即可

实现非常简单 @在PC之前公开作废印刷品{ System.out.println即将调用print Hello World }

我还尝试了其他一些表达方式，如：

@Pointcutexecution@org.springframework.web.bind.annotation.RequestMapping公共*appname.*。。还有很多其他的没有运气。我开始想问题不是我已经试过的10-15种表达方式。。。但该类未在上下文中考虑

关于答案，请考虑：

例如，appname这个名称的目的是显而易见的插入aop:config和aop:aspectj autoproxy只是一种尝试，因为我还在其他线程中读到，必须在applicationContext加载的每个文件中启用配置。我也试着只插入一个，但没有结果控制器具有带注释的接口+带注释的实现。我还尝试了不注释接口或完全删除，但没有结果有什么帮助吗

编辑：响应axtavt。。对不起，我忘了添加我的web.xml，这是其中的一部分

<servlet>
<description>context-servlet</description>
    <servlet-name>appname Servlet</servlet-name>
    <servlet-class>
        org.springframework.web.servlet.DispatcherServlet
    </servlet-class>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>
            classpath:appname-web-context.xml
        </param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

我通过web-context.xml文件正确加载contextConfigLocation。对不起，我忘了：-

EDIT2：我是在axtavt的建议下，犯了错误才得到答案的！谢谢

AOP是按上下文配置的

您有两个上下文—根web应用程序上下文applicationContext.xml，其中包括导入到其中的配置文件，以及DispatcherServlet的应用程序上下文，其中声明了控制器bean

所以，为了将方面应用于控制器，您需要添加。

更新问题。所以我很好地定义了dispatcher上下文，但问题与多个上下文有关：可能是组件扫描？更新：谢谢。我发现我遗漏了什么：在DispatcherServlet上下文下扫描正确的包！我正确地扫描了应用程序上下文的所有其他文件，但没有扫描到这个文件，因为它只是请求的..我错过了它！再次感谢你！
