spring MVC 接收PUT方式请求

PUT方式很少用

定义方法时

@RequestMapping(value = "/checkin", method = RequestMethod.PUT)
    public User checkin(HttpServletRequest request,
                        HttpServletResponse response, ModelMap modelMap, @RequestBody String data){
        System.out.println(data);
        User user = new User();
        return user;
    }

@RequestBody String data

就可以直接接收put的字符串了。
