為什么我收到406不可接受的答復？

Question

這是我的代碼

$.ajax({

                    url: "DataGridServlet.htm",
                    type: "GET",
                    traditional: true,
                    dataType: 'JSON',
                    cache: false,
                    contentType:"application/json",
                    success: function (response){

                       console.log(response);
                   }
                   });

            });

當我向控制器發送請求時..每個都在工作，但是wnem返回JSONObject，我得到的狀態碼是406，這是不可接受的。

及以下的彈簧控制器代碼

@RequestMapping(value="/DataGridServlet.htm", method = RequestMethod.GET,produces="application/json",headers="Accept=*/*")
    public @ResponseBody JSONObject getReturnData()
    {
       System.out.println("control came into conroller");
       JSONObject dataObject=new JSONObject();
       dataObject=jqTabsGridDataDao.getTabsData();
       System.out.println("controller data"+dataObject);
       return dataObject;
    }

有人可以幫助我嗎？

Answer 1

更改

@RequestMapping(value="/DataGridServlet.htm", method = RequestMethod.GET,produces="application/json",headers="Accept=*/*")

至

@RequestMapping(value="/DataGridServlet.htm", method = RequestMethod.GET,produces="application/json",)

和這個

$.ajax({

                    url: "DataGridServlet.htm",
                    type: "GET",
                    traditional: true,
                    dataType: 'JSON',
                    cache: false,
                    contentType:"application/json",
                    success: function (response){

                       console.log(response);
                   }
                   });

            });

至

    $.ajax({
                url: 'DataGridServlet.htm',
                type: "GET",
                headers: {
                    'Accept': 'application/json',
                    'Content-Type': 'application/json'
                },
                success: function(result) {
                    alert(result + " result ");
                },
                error: function(resError) {

                    //alert(resError + " Error ");
                }
});
