acegi 拦截struts2的方法，急！！！分数不够可再加！！！！

Question

使用SSH做一个项目，其中使用到了struts2，权限访问控制使用了acegi，通过acegi可以对URL进行很好的控制了，但是对struts2的方法的控制却不行，查了好多，也没找到什么好方法，请各位高人看看那里配置的不对。现在的情况是如果只有methodSecurityInterceptor这部分，那么运行不报错，但是也没有实现权限的控制，如果按下面的写法，结果总是报org.acegisecurity.AuthenticationCredentialsNotFoundException: An Authentication object was not found in the SecurityContext错误，我怀疑是<property name="beanNames"><list><value>budget</value></list>中的budget无法解析，但是，budget是在spring中配置了的bean，它对应的是
<bean id="budget" class="action.budget.BudgetAction">
 <property name="budgetService" ><ref bean="budgetService" /></property>
</bean>，是在另外一个文件中定义的，我们其它部分的运行都是没问题的，实在不知道这里是怎么回事了，请大家帮帮忙，谢谢<!-- 测试对方法的拦截 -->
<bean id="methodSecurityInterceptor"
class="org.acegisecurity.intercept.method.aopalliance.MethodSecurityInterceptor">
<property name="authenticationManager">
<ref bean="authenticationManager" />
</property>
<property name="accessDecisionManager">
<ref bean="accessDecisionManager" />
</property>
<property name="objectDefinitionSource">
<value>
action.budget.BudgetAction.addbudget=ROLE_ADMIN,ROLE_BUDGET_ADMIN
</value>
</property>
</bean>
<bean id="autoProxyCreator"
class="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator">
<property name="beanNames">
<list>
<value>budget</value>
</list>
</property>
<property name="interceptorNames">
<list>
<value>methodSecurityInterceptor</value>
</list>
</property>
</bean>

Answer 1

<list> <value>budget </value> </list>中的budget无法解析，但是，budget是在spring中配置了的bean，
要是bean的话应该用<ref bean="budget"/>

Answer 2

web.xml中应该配置了吧
要把acegi的配置放到struts2 FilterDispatcher的前面

Answer 4

zidasine，我按照你的提示在web.xml中做了如下修改，结果以前能进行登录的用户现在登录不进去了……，下面的代码是根据提示修改的
<filter>
        <filter-name>AcegiFilterChainProxy</filter-name>
        <filter-class>org.acegisecurity.util.FilterToBeanProxy</filter-class>
        <init-param>
            <param-name>targetClass</param-name>
            <param-value>org.acegisecurity.util.FilterChainProxy</param-value>
        </init-param>
  </filter>
  
    <filter-mapping>
<filter-name>AcegiFilterChainProxy</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
  
  <filter>
<filter-name>struts2</filter-name>
<filter-class>
org.apache.struts2.dispatcher.FilterDispatcher
</filter-class>
  </filter>  <filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
  </filter-mapping>  以前用户可以正常登陆的配制为
<filter>
        <filter-name>AcegiFilterChainProxy</filter-name>
        <filter-class>org.acegisecurity.util.FilterToBeanProxy</filter-class>
        <init-param>
            <param-name>targetClass</param-name>
            <param-value>org.acegisecurity.util.FilterChainProxy</param-value>
        </init-param>
  </filter>
        
  <filter>
<filter-name>struts2</filter-name>
<filter-class>
org.apache.struts2.dispatcher.FilterDispatcher
</filter-class>
  </filter>  <filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
  </filter-mapping>     
    <filter-mapping>
<filter-name>AcegiFilterChainProxy</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

终于搞定了，zidasine说的对，我又整理了一下，之所以我的改成这样无法登录，是因为，我允许输入中文名进行登录的，现在只要把中文名转一下码就行了，揭帖
   <filter>
        <filter-name>AcegiFilterChainProxy</filter-name>
        <filter-class>org.acegisecurity.util.FilterToBeanProxy</filter-class>
        <init-param>
            <param-name>targetClass</param-name>
            <param-value>org.acegisecurity.util.FilterChainProxy</param-value>
        </init-param>
  </filter>
  
  <filter>
<filter-name>struts2</filter-name>
<filter-class>
org.apache.struts2.dispatcher.FilterDispatcher
</filter-class>
  </filter>   <filter-mapping>
<filter-name>AcegiFilterChainProxy</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

  <filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
  </filter-mapping>
