struts2全局拦截器

<package name="abstract_struts" abstract="true"
  extends="struts-default" namespace="/">
  <interceptors>
   <interceptor-stack name="myStack">
    <interceptor-ref name="defaultStack"></interceptor-ref>
    <interceptor-ref name="auth"></interceptor-ref>
    <interceptor-ref name="log"></interceptor-ref>
   </interceptor-stack>
   <interceptor name="auth" class="org.philwong.core.util.AuthInterceptor" />
   <interceptor name="log" class="org.philwong.core.util.LogInterceptor"/>
  </interceptors>
  
  <default-interceptor-ref name="myStack" />
  
  <global-results>
   <result name="login">/platform/common/tologin.jsp</result>
   <result name="tologin">/platform/common/login.jsp</result>
   <result name="noauth" type="redirect">
    /include/noauth.jsp
   </result>
  </global-results>
 </package>

首先在struts.xml中配置一个全局的package继承struts-default,命名为abstract_struts，然后在别的配置文件继承这个abstract_struts
<package name="sysDept" extends="abstract_struts" namespace="/">
