Jsp 无法成功重定向Struts 2中的操作

我正在运行struts 2，并且已经成功地连接到我的SQL server，一切正常，只是我尝试以不同的方式重定向我的用户和管理员，例如当有人登录到web时，我想将他重定向到homepage.jsp（如果他是普通用户）或control.jsp（如果他是页面管理员）我没有让这部分工作，我有以下代码，但用户和管理员都被重定向到管理页面。如果有人能告诉我我的错误，或者我遗漏的任何其他信息来补充，那就太好了

struts.xml

<!-- Login Function -->
<action name="Login" class="Actions.Login">
        <result type="redirectAction">
            <param name="actionName">LevelofAccess</param>
        </result>
        <result name="input">Index.jsp</result>
</action>
<action name="LevelofAccess" class="Actions.LevelofAccess">
        <result name="success">/WEB-INF/Control.jsp</result>
        <result name="input">/WEB-INF/Homepage.jsp</result>
        </action>

您需要从操作方法返回不同的结果才能使用不同的配置结果。是否返回不同的结果？在什么方面，仅仅拥有“return”不意味着默认情况下它是return输入吗？？？如果不是，你到底在暗示什么？添加附加操作包？？您的操作方法

execute

始终返回

SUCCESS

。

validate

方法用于验证，而不是action方法（）。哦，基本上我必须在您在struts.xml中为该操作定义的

execute

函数？In action方法下配置我的结果（

execute

是默认的操作方法）。考虑先阅读一些教程。
