解决方案:
引起该错误的原因是拦截器的声明和引用没有配置在同一个package下
所以使用拦截器时一定要注意,拦截器的声明和引用必须配置在同一package下
如果如下配置,则一定会报出上述错误,因为拦截器声明在name为portal的package中,而拦截器的引用是在name为test的package中：
<struts>
<constant name="struts.objectFactory" value="spring" />
<include file="struts-default.xml"></include>
<package name="portal" extends="struts-default">
<interceptors>
<interceptor name="myInterceptor" type="chain">login</result>
</global-results>
<action name="prepareUserIndex" method="prepareUserIndex">
<interceptor-ref name="myInterceptor"></interceptor-ref>
<result name="success">/WEB-INF/jsp/userIndex.jsp</result>
</action>
<action name="ajaxShowVisitedApps" method="showVisitedAppsInfo">
<interceptor-ref name="myInterceptor"></interceptor-ref>
<result name="success">/WEB-INF/jsp/visitedAppsInfo.jsp</result>
</action>
</package>
<package name="test" extends="json-default">
<action name="ajaxGetAppRemarkStatus" method="getAppRemarkStatus">
<interceptor-ref name="myInterceptor1"></interceptor-ref>
<result name="success" type="json">
<param name="root">isLiked</param>
</result>
</action>
</package>
</struts>
