Js

var json = {name: "chelovek", l_name: "chelovek2", age: 22} $('#button').click(function(){ $.ajax("ajax",{ type:"POST", contentType:"application/json", data:'jsonDATA'+JSON.stringify(json), success:function(data){ $('#value').html(data); }} ); });

Controller

 @Controller @RequestMapping("/ajax") public class ajaxcontroller { @RequestMapping(method= RequestMethod.POST) @ResponseBody public String hi(HttpServletRequest request){ //вот так взял просто текст.а как взять json из параметра не знаю AsyncContext str = request.getAsyncContext(); return "SPRING MVC " + str; } }

How to get data from JSON in a Spring MVC controller?

    Model:

     public class Person { private String name; private String l_name; private int age; // getters & setters ... }

    Controller:

     @RequestMapping(value = "/addPerson", method = RequestMethod.POST, headers = {"Content-type=application/json"}) @ResponseBody public JsonResponse addPerson(@RequestBody Person person) { logger.debug(person.toString()); return new JsonResponse("OK","");

    Response:

     public class JsonResponse { private String status = ""; private String errorMessage = ""; public JsonResponse(String status, String errorMessage) { this.status = status; this.errorMessage = errorMessage; } }

    ajax (example):

     $.ajax({ type: "POST", url: "addPerson", data: JSON.stringify({ name: "chelovek", l_name: "chelovek2", age: 22 }), contentType: 'application/json', success: function(data) { if(data.status == 'OK') alert('Person has been added'); else alert('Failed adding person: ' + data.status + ', ' + data.errorMessage); } });
