获取json数据     名字一样就获取了

user
1     @RequestMapping("/addUser")2     public String addUser(User user,HttpServletRequest request){3         request.setAttribute("userName", user.getUserName());4         request.setAttribute("age", user.getAge());5         6         return "/userManager";7     }

 

传递json数据

 1     public void addUserJson(User user,HttpServletRequest request,HttpServletResponse response){ 2         //{"username":"userName","age","age"} 3         String result = "{\"userName\":\" "+ user.getUserName() +" \",\"age\":\" "+ user.getAge()+" \"}"; 4         PrintWriter out = null; 5         response.setContentType("application/json"); 6          7         try { 8             out = response.getWriter(); 9             out.write(result);10         } catch (IOException e) {11             e.printStackTrace();12         }13         14     }
