当我提交注册表时，传递给Action类的输入值为null。如何在register（）方法下访问action类中的注册值

上述问题已得到解决

现在我面临另一个奇怪的问题。。当我提交表单action=getLogin.action时，它总是从拦截器返回输入。我不希望从验证器中排除方法登录

我该怎么解决呢

当我像下面这样更改StrutsXML时，它将重定向到成功jsp。但是我不想从验证中排除登录方法

       <action name="getLogin" class="login.action.LoginAction"
        method="login">
                            <interceptor-ref name="defaultStack">
            <param name="validation.excludeMethods">login</param>
        </interceptor-ref>
        <result name="success">/Success.jsp</result>
        <result name="input">/LoginError.jsp</result>
    </action>


登录
/Success.jsp
/LoginError.jsp

如果只使用一个拦截器，则需要使用整个堆栈：
