Spring mvc控制器不会重定向到正确的jsp页面

Question

所以我在landing.jsp

上有这个

    <div class="nav-right nav-menu" id="nav-menu">
      <a class="nav-item is-hidden-tablet is-active roboto strong letter-space-1" href="toLoginPage.action">HOME</a>
      <a class="nav-item is-hidden-tablet roboto strong letter-space-1" href="about.action"/>"> ABOUT </a>
      <a class="nav-item is-hidden-tablet roboto strong letter-space-1" href="contact.html"> CONTACT </a>
      <a class="nav-item roboto strong letter-space-1" id="login-btn"> LOGIN </a>
    </div>

因此，我尝试做的是当我在着陆页（landing.jsp）上时，我希望用户能够通过单击着陆页的导航栏导航到about页面。但一般来说，它不会切换jsp＆​​＃39>

这是我的控制器

    @RequestMapping(value="toLoginPage")
@ResponseBody
public String toNewLoginPage(HttpServletRequest request, HttpServletResponse response){

    Cookie[] cookieArr=request.getCookies();
    if(cookieArr==null) {
            return "login/landing";
    }
    for(Cookie cookie:cookieArr){
        System.out.println(cookie.getName());
        if(cookie.getName().equals("userInfo")){
            String userIdStr=cookie.getValue();
            long userId=Long.parseLong(userIdStr);
            UserBean userBean=userService.getUserById(userId);
            HttpSession session=request.getSession();
            session.setAttribute(Constant.SESSION_USER, userBean.getId()+"");
            if(userBean.getIsActive()==1){
                session.setAttribute(Constant.SESSION_IS_ACTIVE, true);
            }else{
                session.setAttribute(Constant.SESSION_IS_ACTIVE, false);
            }
            request.setAttribute("MsgModuleUrl", CurisConfig.CurisConfig.MODULE_ADDRESS.MsgModule);
            request.setAttribute("formula", CurisConfig.CurisConfig.MODULE_ADDRESS.CurisForum);
            return "index/index";
        }
    }

    //compare the servlet request url and redirect to 
    return "login/landing";

}

    @RequestMapping(value="about")
public ModelAndView aboutPage(HttpServletRequest request,HttpServletResponse response) {

    Cookie[] cookieArr=request.getCookies();
    if(cookieArr==null) {
            return new ModelAndView("login/landing");
    }
    for(Cookie cookie:cookieArr){
        System.out.println(cookie.getName());
        if(cookie.getName().equals("userInfo")){
            String userIdStr=cookie.getValue();
            long userId=Long.parseLong(userIdStr);
            UserBean userBean=userService.getUserById(userId);
            HttpSession session=request.getSession();
            session.setAttribute(Constant.SESSION_USER, userBean.getId()+"");
            if(userBean.getIsActive()==1){
                session.setAttribute(Constant.SESSION_IS_ACTIVE, true);
            }else{
                session.setAttribute(Constant.SESSION_IS_ACTIVE, false);
            }
            request.setAttribute("MsgModuleUrl", CurisConfig.CurisConfig.MODULE_ADDRESS.MsgModule);
            request.setAttribute("formula", CurisConfig.CurisConfig.MODULE_ADDRESS.CurisForum);
            return new ModelAndView("index/index");
        }
    }

    return new ModelAndView("login/about");
}

所以你可以看到我在某种程度上与我返回请求的方式不一致，但我试图看看ModelAndView是否可行，因为String实现不会。
