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 }
