本文介绍了一个使用Spring MVC实现JSON数据交互的例子，包括如何通过Ajax发送POST请求传递JSON数据，并在服务器端接收处理这些数据。

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     }

jsp
