点击忘记密码又回到登录页面？

Question

我的系统是二次开发，我不知道为什么当点击忘记密码的时候，又回到登录页面，用的spring
和springMvc ，找不到是哪个东西给拦截了，点击忘记密码的那个action进不去？

 @RequestMapping("forget-password")
    public String forgotPassword(ModelMap model) {
        this.setLayout(LayoutType.EMPTY);
        System.out.println("TTTTTTTTTTTTTTTTTTTTTTTT");
        return "forgot-password";
    }

1. F12 ， 查看是否向后台发送请求。
2. web.xml文件，是否注册filter，对这个请求过滤。
3. debug ， springMVC对这个请求的处理，以及它的返回值。
