第一种：通过@RequestBody，直接将请求体映射到对象

1 //@RequestBody
2     @RequestMapping(value = "addUser", method = {RequestMethod.GET, RequestMethod.POST})
3     public @ResponseBody
4     String addUser(HttpServletRequest request, @RequestBody User user) {
5         logger.debug(request.getRemoteAddr());
6         return userServices.addUser(user);
7     }

 请求：

 

响应：

 第二种：通过@RequestBody，获取请求头部字段

1 //@RequestHeader
2     @RequestMapping(value = "addUser/header", method = {RequestMethod.GET, RequestMethod.POST})
3     public @ResponseBody
4     String addUser_header(HttpServletRequest request, @RequestBody User user,@RequestHeader("Accept-Encoding") String encoding,@RequestHeader("Content-Type") String type) {
5         logger.debug(request.getRemoteAddr());
6         logger.debug("Accept-Encoding:{}",encoding);
7         logger.debug("Content-Type:{}",type);
8         return userServices.addUser(user);
9     }

  第三种：通过@PathVariable，获取url template 里的参数

 1 //@PathVariable
 2     @RequestMapping(value = "addUser/{name}/{age}", method = {RequestMethod.GET, RequestMethod.POST})
 3     public @ResponseBody
 4     String addUser_path(HttpServletRequest request, @PathVariable("name") String name, @PathVariable("age") String age) {
 5         logger.debug(request.getRemoteAddr());
 6         User user = new User();
 7         user.setAge(age);
 8         user.setName(name);
 9         return userServices.addUser(user);
10     }

第四种：通过@RequestParam，获取请求参数

 1 //@RequestParam
 2     @RequestMapping(value = "addUser_param", method = {RequestMethod.GET, RequestMethod.POST})
 3     public @ResponseBody
 4     String addUser_params(HttpServletRequest request, @RequestParam("name") String name, @RequestParam("age") String age) {
 5         logger.debug(request.getRemoteAddr());
 6         User user2 = new User();
 7         user2.setAge(age);
 8         user2.setName(name);
 9         return userServices.addUser(user2);
10     }

 请求1：post请求

请求2：get请求
