aop拦截器没拦住，求教了
xml:

XML code

    <bean id="chkLoginAdvice" class="com.zjm.study.advice.chkLoginAdvice" />    <aop:config>        <aop:advisor pointcut="execution(* com.zjm.struts.action.LoginAction.login(..))" advice-ref="chkLoginAdvice" />    </aop:config>

action:

Java code

package com.zjm.struts.action;public class LoginAction extends DispatchAction {    //分发action    public ActionForward login(ActionMapping mapping............) {        //.........    }}

around拦截器：

Java code

package com.zjm.study.advice;public class chkLoginAdvice implements MethodInterceptor {    public Object invoke(MethodInvocation arg0) throws Throwable {        System.out.println("测试拦截");       //这句没打印出来，没拦住.....        return null;    }}

没拦住啊，拦截器里打印的“测试拦截”，控制台没有

[解决办法]
好像spring的aop拦截不到继承自dispathcerAction的方法
