JSON Post to Spring 控制器不工作....我进入控制器，但后来我遇到了一些疯狂的错误。

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>

java/弹簧/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);
    }

现在对于错误：

将查询字符串转换为json字符串

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

在ajax帖子中传递json字符串而不是queryString

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

试试这个，它适用于 Java servlet doPost()。$(文档).ready(函数(){

  $("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);
          }
        }); 
  });

});
