解决SpringMVC接收不到ajaxPOST参数的问题

 @PostMapping(value = "/method")
 @ResponseBody
 public   method(Integer id,String audit_content) {
  return null;
 }

  var data = {id:7,audit_content:"11111111111111111111a1"};
  $.ajax({
   type: "POST",
   url: "/method",
   data:data,
   contentType: "application/json;charset=utf-8",
   success: function (result) {
    $("#my_result").html(JSON.stringify(result));
   },
   error: function () {
    console.log("shibai")
   }
  });

 @PostMapping("/method2")
 @ResponseBody
 @Transactional
 public   method2(@RequestBody Body body) {
  return null;
 }

  var data = {"id": i, "show_status":0};
  $.ajax({
   type: "POST",
   url: "/method2",
   data: JSON.stringify(data),
   contentType: "application/json;charset=utf-8",
   success: function (result) {
    $("#my_result").html(JSON.stringify(result));
   },
   error: function () {
    console.log("shibai")
   }
  });
