springmvc json结合

获取json数据名字一样就获取了

user

     @RequestMapping("/addUser")

     public String addUser(User user,HttpServletRequest request){

         request.setAttribute("userName", user.getUserName());

         request.setAttribute("age", user.getAge());

         return "/userManager";

     }

传递json数据

     public void addUserJson(User user,HttpServletRequest request,HttpServletResponse response){

         //{"username":"userName","age","age"}

         String result = "{\"userName\":\" "+ user.getUserName() +" \",\"age\":\" "+ user.getAge()+" \"}";

         PrintWriter out = null;

         response.setContentType("application/json");

         try {

             out = response.getWriter();

             out.write(result);

         } catch (IOException e) {

             e.printStackTrace();

         }

     }

             var age =$("#age").attr("value");

             var user = {userName:userName,age:age};

             $.ajax({

                 url:"/springMVC6/user/data/addUserJson",

                 type:"post",

                 data:user,

                 success:function(a){             　　//传递过来数据

                     alert("userName--->" + a.userName + "age--->" + a.age );

                 }

             });

         });

     });
