spring整合struts使用AOP拦截action不成功，如何解决？

[dgqbcht]

想用aop做用户验证，代码如下：
ClassAction：
package action;

import java.util.List;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;

import aop.Interface.StrutsAction;

import service.ClassManage;
import vo.Class;

public class ClassManageAction extends Action{
private ClassManage classManage;

public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) {
……
}

public void setClassManage(ClassManage classManage) {
this.classManage = classManage;
}

}

struts-config.xml:
<struts-config>
<data-sources />
<form-beans>
<form-bean name="class" type="vo.Class"/>
</form-beans>
<global-exceptions />
<global-forwards > </global-forwards>
<action-mappings >

<action path="/classManage" type="org.springframework.web.struts.DelegatingActionProxy"
name="class">
<forward name="" path=""></forward>
</action>
</action-mappings>
<message-resources parameter="ApplicationResources" />
<plug-in className="org.springframework.web.struts.ContextLoaderPlugIn">
<set-property property="contextConfigLocation" value="/WEB-INF/applicationContext.xml" />
</plug-in>
</struts-config>

拦截器:
package aop.advice;

import org.aopalliance.intercept.MethodInterceptor;
import org.aopalliance.intercept.MethodInvocation;
import service.AuthorityService;

public class AuthorityCheckAroundAdvice implements MethodInterceptor{
private AuthorityService authorityService;

public Object invoke(MethodInvocation invocation) throws Throwable {
System.out.println(invocation.getMethod().getDeclaringClass());
invocation.proceed();
return null;
}

public void setAuthorityService(AuthorityService authorityService) {
this.authorityService = authorityService;
}
}

spring配置文件：applicationContext.xml
<beans>
<bean id="classManage" class="service.impl.ClassManageImpl">
<property name="classDAO">
<ref local="classDAO" />
</property>
</bean>

<bean name="/classManage" class="action.ClassManageAction">
<property name="classManage">
<ref local="classManage" />
</property>
</bean>

<bean id="advice" class="aop.advice.AuthorityCheckAroundAdvice">
<property name="authorityService">
<ref local="authorityService"/>
</property>
</bean>
<bean id="aopAuthorityCheck" class="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator">
<property name="beanNames">
<list>
<value>/classManage</value>
</list>
</property>
<property name="interceptorNames">
<list>
<value>advice</value>
</list>
</property>
</bean>
<bean id="classDAO" class="dao.impl.ClassDAOImpl" parent="superDAO"></bean>
</beans>

运行时报错：

大概的意思是拦截的对象应该是个Struts的Action类，但是现在拦截到的是个代理。
但是spring整合struts本身用的确实是代理org.springframework.web.struts.DelegatingActionProxy，请问有经验的朋友如何解决，谢谢！

好象是你在Struts-config中没有设置启动容器为Spring..

[karlpan01]

呵呵,我只能帮你顶!

[for_cyan]

既然用了DelegatingActionProxy，就在spring的配置文件中配置所有的bean，包括struts的action
在/WEB-INF/applicationContext.xml设置AOP代理，以及拦截的bean，其实struts的配置文件完全可以省略了
不过你用插件的方式加载sping的话就不能省了，最好用listener和servlet

[myth822]

没有做过对action的拦截,不过看了一下
getDelegateAction中的方法是
return (Action) wac.getBean(beanName, Action.class);
所以spring总会验证你的类是否是Action的子类

你可以用正则拦截execute方法来代替拦截action类

[dgqbcht]

目前折衷的解决方案只有自己写个MyDelegatingActionProxy，继承DelegatingActionProxy，然后override里面的execute方法，直接在这里做判断，跟aop使用代理的思想一致，但没有能够真正用到springframework里的aop。

Action 是否继承 extends DispatchAction
