Global Results(全局结果集) ----struts2

Global Results(全局结果集)
Global Results(全局结果集)
即为共用的action
配置：
    <package name="user" namespace="/user" extends="struts-default">
            <global-results>
                <result name="mainpage">/main.jsp</result>
            </global-results>
            <action name="index">
                <result>/index.jsp</result>
            </action>
         <action name="user" class="com.bjsxt.struts2.user.action.UserAction">
                <result>/user_success.jsp</result>
                <result name="error">/user_error.jsp</result>
        </action>       
</package>

如果其他包中也需要用到这个全局结果集，需要用到package的extends
<package name="admin" namespace="/admin" extends ="user">
            <action name="admin" class="com.bjsxt.struts2.user.action.AdminAction">
                <result>/admin.jsp</result>
            </action>
</package>
