SpringMVC+AspectJ 未调用

Question

您好，我阅读了有关我的问题的所有先前主题，并应用了所有建议，但我还没有找到解决方案。
在我的 springMVC+AspectJ 配置中，控制器工作正常，但没有执行切入点。 这是我的配置和代码：

-- /WEB-INF/web.xml ---
        <web-app>
          <display-name>MODULE-WEB</display-name>

          <context-param>
                <param-name>contextConfigLocation</param-name>
                <param-value>WEB-INF/applicationContext.xml</param-value>
            </context-param>

           <listener>
            <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
           </listener> 
        ...

            </bean> 

            </beans>

你的注解方法是protected，但应该是public。

Spring manual, chapter 9.2.3 说：

由于 Spring 的 AOP 框架基于代理的性质，根据定义，受保护的方法不会被拦截，对于 JDK 代理（如果不适用）和 CGLIB 代理（这在技术上可行但不推荐用于 AOP目的）。因此，任何给定的切入点都只会与公共方法匹配！

如果您想匹配 protected 或 private 方法，请通过 LTW 使用 AspectJ。
