</interceptor-stack>

如果有多個自定義的interceptor
使用interceptor stack的形式來處理比較方便

<interceptors>
<interceptor-stack name="myStack">
<interceptor-ref name="i18n" />
<interceptor-ref name="params" />
<interceptor-ref name="static-params" />
<interceptor-ref name="LoginInterceptor" /> <!--自定義的-->
</interceptor-stack>
<interceptor name ="LoginInterceptor" class ="myClass" />
</interceptors>

直接引用interceptor stack就不用一個一個加了

<action name="myAction" class="myClass">
<interceptor-ref name="myStack"/>
...
</action>
