JSON發佈到春季控制器不工作....我進入控制器，但後來我得到一些瘋狂的錯誤。JSON發佈到春季控制器不工作

的Javascript：

function doAjaxPost() { 

    alert("doAjaxPost Called"); 

    var queryString = $('#htmlform').serialize(); 

     $.ajax({ 
      contentType : "application/json", 
      dataType : 'json', 
      type : "POST", 
      url : contexPath + "/service/employee", 
      data : queryString, //json serialization (like array.serializeArray() etc) 

      success : function(data) { 
       alert("Thanks for submitting. \n\n" + response.result); 
       // response 
      }, 
      error : function(request, status, error) { 
        alert('Error: ' + e); 
      } 
     }); 
    } 
</script>

的Java /春/控制器：

@RequestMapping(headers ={"application/json;charset=UTF-8"}, method=RequestMethod.POST, value="/employee") 
    public ModelAndView updateEmployee(@RequestBody Employee employee) { 
     System.out.println("in put body:"); 
     System.out.println("HELLO WORD" + employee.toString()); 

     return new ModelAndView(XML_VIEW_NAME, "object", employee); 
    }

現在的錯誤：

錯誤是'addEmployee'，但您粘貼'updateEmployee'。你能解決這個問題嗎？而且還可能添加行號到控制器所以我們可以通過堆棧跟蹤來交叉引用 –

你是否正在通過POST請求填充'Employee'模型，是的，如果你改正了你的堆棧跟蹤會更好，它沒有顯示你寫的SOP語句。 –

轉換的查詢字符串JSON字符串

var postData = {}; 
jQuery.map($('#htmlform').serializeArray(), function(n, i){ 
postData[n['name']] = n['value']; 
});

通JSON字符串，而不是在的queryString後阿賈克斯

$.ajax({ 
      data : JSON.stringify(postData), //convert json object to string 
      success : function(data) {     
      }, 
      error : function(request, status, error) { 
      } 
});

試試這個，我的作品上的Java servlet的doPost（）。 $（文件）。就緒（函數（）{

$("button").click(function(){ 
     var mydata = {"name":"abc","age":"25"}; 
     $.ajax({ 
      type: "POST", 
      url: "http://localhost:8080/...", 
      data: JSON.stringify(mydata), 
      contentType: "application/json; charset=utf-8", 
      dataType: "json", 
      success:function(data){ 
      if(data.status === "success"){ 
       alert("Success"); 
      } else if (data.status === "error"){ 
       alert("Fail"); 
      } 
      }, 
      error:function(thrownError){ 
      console.log(thrownError); 
      } 
     }); 
    });

});
