Struts2.0和sping3.0结合 诡异异常Unable to instantiate Action
本人在整合一个小项目，struts2.2.3版本和sping3.0结合 在登陆页面点击登陆的时候（action路径为：login.action）报了一个很诡异的异常，查了很多资料无人解读，希望有人帮忙解决一下：
exception

。。。。。。。。。。。

在只有struts的时候项目运行是没有问题的 但是加入了sping之后就遇到了顶上的这个问题。浪费了很长时间。下面是我的配置文件：

struts.xml:

<constant name="struts.objectFactory" value="spring" />

<package name="default" extends="struts-default" >
<interceptors>
<!-- 定义AuthenticationInterceptor拦截器 -->
<interceptor name="auth" 
class="interceptor.AuthenticationInterceptor"/>

<!-- 定义我们自己的拦截器栈，在Action的配置中，可以直接引用这个拦截器栈 -->
<interceptor-stack name="securityStack">

<interceptor-ref name="auth"/>
<interceptor-ref name="defaultStack">
<param name="workflow.excludeMethods">default</param>
<param name="validation.excludeMethods">default</param>
</interceptor-ref>
 
</interceptor-stack>
</interceptors>

<default-interceptor-ref name="securityStack"></default-interceptor-ref>

<action name="admin" class="action.AdminAction">

</action>
 
 
 
<action name="login" class="loginAction">

<result name="login">/index.jsp</result>
</action>
   
  </package>

applicationContext.xml:

<bean id="loginAction"
