接收有效负载请求并使用spring在网页上显示它

Question

首先，我是 var dataObject = { dateData: New Date('16-01-01 15:30') } console.log(dataObject); $.ajax({ type: "POST", url: '@Url.Content("~/Service/DateTest")', dataType: "json", data: dataObject, }, success: function (response) { } }); } 的新手并尽力使其发挥作用。所以这是我的问题。

我有一个spring MVC项目，该项目应该接收请求有效负载（JSON请求）并在网页上显示有效负载主体。请参阅我的项目内容和下面的控制器类

  public ActionResult DateTest(DateObject data)
        {
            return Json("ok", JsonRequestBehavior.AllowGet);
        }

现在，如果我使用Spring向@Controller public class CallbackPayloadController { public CallbackPayloadController() { System.out.println("In controller class!!!!"); } @RequestMapping(value = "/requestreceiver", consumes = "application/json", method = RequestMethod.POST) public void receivePayload(@RequestBody String payload) { System.out.println("In the controller method...."); System.out.println("Payload is : " + payload); } } 发帖，则会显示http://localhost:8080/PayloadReceiver/requestreceiver/。我发布的Json内容是

POSTMAN

我的HTTP STATUS 404如下

{
"key":"123"
}

第二个问题是，如果我成功收到有效负载，如何在新网页上显示有效负载内容？

尝试将return语句添加到您的方法中，如下所示：

    @RequestMapping(value = "/requestreceiver",consumes="...",method = RequestMethod.POST)
    public String receivePayload(...)
    ...
    return "requestreceiver";
