struts2 页面间跳转问题

Question

struts2的配置
struts.xml核心配置

 package name="app" extends="struts-default" namespace="/">
        <!-- app/模块/类名/方法名 -->
        <action name="app/*/*/*" class="com.demo.app.{1}.action.{2}Action"
            method="{3}">
            <result name="defaultView">app/index/index/{3}.jsp</result>
            <result name="view">/WEB-INF/jsp/{1}/{2}/${nextPath}.jsp</result>
        </action>
    </package>

Action调用方法，访问的uri=app/index/index/login

 /* public String login(ServletRequest request,ServletResponse response){ */
    public String login() throws NoSuchAlgorithmException, UnsupportedEncodingException{

        HttpServletRequest request = ServletActionContext.getRequest();
        HttpServletResponse response = ServletActionContext.getResponse();
        logger.info("action_uri=="+request.getRequestURI());
        HttpSession session = request.getSession();
        User userExsit = (User) session.getAttribute("user");

        if (userExsit != null) {
            return view("recruitDetail");
        } else {
            String loginname = request.getParameter("mobile");
            String password = request.getParameter("password");
            User us = loginService.findByUserName(loginname);

            if (us != null && us.getLoginPwd() != null && MD5Util.validPasswd(password, us.getLoginPwd())) {

                return view("recruitDetail");-----------（成功执行这条语句，且struts.xml中的${nextPath}值为recruitDetail）
            } else {
                return view("login");
            }

        }

    }
    return 语句用到的view()方法

    public String view(String vPath){

        nextPath = vPath;
        logger.debug("动作完成后，转发到：" + nextPath);
        this.assign("timeStr",
                "" + System.currentTimeMillis() + System.nanoTime());
        this.assign("uuid", UUIDUtil.get32ID());// 为页面传递UUID,用于页面的标识
        return "view";


    }

结果是,我点击登陆后，在调试页面获得了要跳转页面如图：

我的问题是要跳转的页面已经可以在页面debug中查到，说明访问路径没问题，怎么就没有将原来的页面覆盖掉呢，请大神们帮忙解答下，小弟谢谢了，纠结半天了
