struts2 报403 错误

好久没有接触struts2了，今天在写一个简单的网页（jsp）的时候，在整合了struts2时发现一个问题。

详情：

  jsp页面：index.jsp:输入用户名，登陆

                  login.jsp:登陆之后进入login页面：hello

  struts2.xml：

  <action name="login" class = "com.cyan.cloder.action.UserAction" method="addUser">

          <result name="success">view/regist.jsp </result>

   </action>

UserAction:

   就一个execute：return SUCCESS;

启动就报了403的错误。HTTP Status 403 - Access to the requested resource has been denied

后来发现是因为web.xml的问题：

原web.xml:

 <filter>

        <filter-name>struts2</filter-name>

        <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>

    </filter>

    <filter-mapping>

        <filter-name>struts2</filter-name>

        <url-pattern>/*</url-pattern>

    </filter-mapping>

    <welcome-file-list>

        <welcome-file>index.html</welcome-file>

    </welcome-file-list>

    <!-- Restricts access to pure JSP files - access available only via Struts action -->

    <security-constraint>

        <display-name>No direct JSP access</display-name>

        <web-resource-collection>

            <web-resource-name>No-JSP</web-resource-name>

            <url-pattern>*.jsp</url-pattern>

        </web-resource-collection>

        <auth-constraint>

            <role-name>no-users</role-name>

        </auth-constraint>

    </security-constraint>

    <security-role>

        <description>Don't assign users to this role</description>

        <role-name>no-users</role-name>

    </security-role>

更换的web.xml

<filter>

  <filter-name>struts2</filter-name>

  <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>

 </filter>

 <!-- 让Struts 2的核心Filter拦截所有请求 -->

 <filter-mapping>

  <filter-name>struts2</filter-name>

  <url-pattern>/*</url-pattern>

 </filter-mapping>
