我们的项目架构使用 Struts 1 和 Struts 2 和 Spring 3。我正在尝试创建一个 Aspect 以更好地处理异常。Struts 1 直到现在还不是 Spring 管理的 - 所以我点击了这个链接How to integration an old Struts application with Spring 3.x to allow Spring component-scan to pick the Struts 1 Action。

编辑： - 版本

Struts 1 - org.apache.struts.struts-core (1.3.10) Struts 2 - org.apache.struts.struts2-core (2.0.9) Spring - 3.2.2

但我的方面类没有拿起它。我的 struts 2 动作或服务类没有任何问题。但我无法理解这里有什么问题。

异常方面类 -

package com.mnm.abc.aop;
public @Aspect @Component class ExceptionHandler {
    @Pointcut("execution(public * abc.web.action.AbcAction+.doExecute(..))")
    public void inStruts1Action() {
    }

/* I tried the following too
* @Pointcut("within(abc.web.action.AbcAction+)")
* @Pointcut("execution(public * abc.web.action.AbcAction.execute(..))")
* @Pointcut("execution(public * abc.web.action.*.doExecute(..)) && within(abc.web.action.AbcAction+)")
*/
    @After("inStruts1Action()")
    public void after() {
        System.out.println("After");
    }
}

Struts 1 Action 类 -

package abc.web.action;
public @Component class TransactionAction extends AbcAction {
    public @Override ActionForward doExecute(ActionMapping mapping, ActionForm form,
            HttpServletRequest request, HttpServletResponse response)
            throws Exception {
        System.out.println("Hi");
        ActionForward forward = mapping.findForward("success");
        return forward;
    }
}

父类 -

package abc.web.action;
public abstract class AbcAction extends Action {
    public ActionForward execute(ActionMapping mapping, ActionForm form,
            HttpServletRequest request, HttpServletResponse response)
            throws Exception {
        try {
            return doExecute(mapping, form, request, response);
        } catch (Exception e) {
            e.printStackTrace();
            throw e;
        }
    }
    public abstract ActionForward doExecute(ActionMapping mapping,
            ActionForm form, HttpServletRequest request,
            HttpServletResponse response) throws Exception;
}

配置类 -

package com.mnm.abc.config;
@Configuration
@ComponentScan(basePackages = { "abc.web.action", "com.mnm.abc.aop" })
@EnableTransactionManagement
@EnableScheduling
@EnableAspectJAutoProxy(proxyTargetClass=true)
public class DataSourceConfig implements TransactionManagementConfigurer { ... }

当我浏览调试日志时，我收到以下消息

我还阅读了很多关于抽象方法调用和 AOP 的信息，但似乎没有任何效果。请帮帮我。
