Fullcalendar with spring @ResponseBody return Json Array with 406 error :not Acceptable Header

Question

I am trying to send a JSON Array to my fullCalendar which locate on gamesetting.jsp. the json array object has been test through console and It has showing the cerrect answer.then I tried $("#calendar").fullCalendar( 'addEventSource', source ), chrome give back a 406 error and want the response asThe resource identified by this request is only capable of generating responses with characteristics not acceptable according to the request "accept" headers.

@RequestMapping ( method=RequestMethod.GET ,produces={"application/json; charset=UTF-8"}) 
public @ResponseBody JSONObject returnGames(GameVO gameVo,HttpServletResponse response) throws IOException{
    GameService gService= new GameService(gameDao); 
    List<GameVO> games= gService.select(gameVo);
    JSONArray jsonArray = new JSONArray();
    JSONObject jsonObj =null;
    for(GameVO game:games){
        jsonObj = new JSONObject();
        jsonObj.put("game_no", game.getGame_sd());
        jsonObj.put("game_name", game.getGame_name());
        jsonObj.put("game_time", game.getGame_time());
        jsonArray.put(jsonObj);
    }
    System.out.println("jsonArray: "+jsonArray);
    response.setHeader("Accept", "application/json");
 return jsonObj;
}

shown in console

jsonArray: [{"game_name":"A vs B","game_time":"2015-05-20 00:00:00.0","game_no":1}]

and this is my JavaScript code

    $(document).ready(function() {
    $('#calendar').fullCalendar({
            customButtons: {
                myCustomButton: {
                    text: 'custom!',
                    click: function getGames(e){

                        var games;
                        var url='selectAllGames.controller';
                        if (getGames){
                            $.getJSON(url,null,
                                 function(){$("#calendar").fullCalendar( 'addEventSource',url )})
                                 ;}                   
                    console.log(e);    
                    }                         
             }
        },

I really have no clue what's wrong...

What happens when you remove this line `response.setHeader("Accept", "application/json");` — sagarr, Jun 10 '17 at 09:06
@Sagar Rohankar-the response header would have no accept property and still return 406 error with the same description. — Bill EE, Jun 10 '17 at 13:51

You can solve this by changing the ResponseBody from JSONObject to ResponseEntity:
So the server side code is:

@RequestMapping(method=RequestMethod.GET, produces={"application/json; charset=UTF-8"}) 
public @ResponseBody ResponseEntity<String> returnGames(GameVO gameVo, HttpServletResponse response) throws IOException {
    GameService gService = new GameService(gameDao); 
    List<GameVO> games = gService.select(gameVo);
    JSONArray jsonArray = new JSONArray();
    JSONObject jsonObj = null;
    for(GameVO game : games){
        jsonObj = new JSONObject();
        jsonObj.put("game_no", game.getGame_sd());
        jsonObj.put("game_name", game.getGame_name());
        jsonObj.put("game_time", game.getGame_time());
        jsonArray.put(jsonObj);
    }
    //System.out.println("jsonArray: "+jsonArray);
    //response.setHeader("Accept", "application/json");

    HttpHeaders responseHeaders = new HttpHeaders();
    responseHeaders.add("Content-Type", "application/json; charset=utf-8");

    return new ResponseEntity<String>(jsonArray.toString(), responseHeaders, HttpStatus.OK);
}

More on this:
From this page: What is "406-Not Acceptable Response" in HTTP? : "406 happens when the server cannot respond with the accept-header specified in the request. In your case it seems application/json for the response may not be acceptable to the server."

wow! works just as you said!! 406 has gone and this ResponseBody contain the DB Data.Sincerely thanks for your sharing ! — Bill EE, Jun 10 '17 at 14:01
