困扰了一天的struts2拦截器，急

Java code

<package name="hchl" namespace="/hchl" extends="json-default">        <interceptors>            <interceptor name="startInterceptor" class="com.inspur.hchl.interceptor.StartInterceptor">            </interceptor>            <interceptor-stack name="startInterceptorStack">                                     <interceptor-ref name="defaultStack"/>                <interceptor-ref name="startInterceptor"/>            </interceptor-stack>        </interceptors>     <action name="schema_*" class="schemaAction" method="{1}">             <interceptor-ref name="startInterceptor">                 <param name="includeMethods">findAllByPage</param>             </interceptor-ref>             <result type="json">                <param name="defaultEncoding">utf-8</param>            </result>    </action></package>
