Spring MVC 怎么返回一个请求路径

@RequestMapping("/user/creatUser.do")
    /**creat loginUser*/
    public String creatUser(@ModelAttribute("loginUser") LoginUser loginUser) {

        try {
            boolean b = loginuserDao.creatUser(loginUser);
        } catch (Exception e) {
            e.printStackTrace();
            log.error("Class:LogouContrller --menthd:creatUser", e);
        }
        return "";
    }
