JSON发布到Spring Controller [英] JSON post to Spring Controller

问题描述

您好我在Spring中开始使用Web Services，所以我正在尝试在Spring + JSON + Hibernate中开发小型应用程序。我有一些HTTP-POST问题。我创建了一个方法：

Hi I am starting with Web Services in Spring, so I am trying to develop small application in Spring + JSON + Hibernate. I have some problem with HTTP-POST. I created a method:

@RequestMapping(value="/workers/addNewWorker", method = RequestMethod.POST, produces = "application/json", consumes = "application/json")
@ResponseBody
public String addNewWorker(@RequestBody Test test) throws Exception {
    String name = test.name;
    return name;
}

我的模特测试看起来像：

And my model Test looks like:

public class Test implements Serializable {

private static final long serialVersionUID = -1764970284520387975L;
public String name;

public Test() {
}
}

通过POSTMAN我只发送JSON {name：testName}并且我总是收到错误;

By POSTMAN I am sending simply JSON {"name":"testName"} and I always get error;

The server refused this request because the request entity is in a format not supported by the requested resource for the requested method.

我导入了Jackson库。我的GET方法运行正常。我不知道我做错了什么。我很感激任何建议。

I imported Jackson library. My GET methods works fine. I don't know what I'm doing wrong. I am grateful for any suggestions.

推荐答案

使用

JSON.stringify（{name：testName}）

或手动。 @RequestBody期待json字符串而不是json对象。

or manually. @RequestBody expecting json string instead of json object.

注意：stringify函数有一些IE版本有问题，firefox会有效吗

Note:stringify function having issue with some IE version, firefox it will work

验证您的POST请求的ajax请求的语法。 ajax请求中需要 processData：false 属性

verify the syntax of your ajax request for POST request. processData:false property is required in ajax request

$.ajax({ 
    url:urlName,
    type:"POST", 
    contentType: "application/json; charset=utf-8",
    data: jsonString, //Stringified Json Object
    async: false,    //Cross-domain requests and dataType: "jsonp" requests do not support synchronous operation
    cache: false,    //This will force requested pages not to be cached by the browser  
     processData:false, //To avoid making query String instead of JSON
     success: function(resposeJsonObject){
        // Success Action
    }
});

控制器

@RequestMapping(value = urlPattern , method = RequestMethod.POST)

public @ResponseBody Test addNewWorker(@RequestBody Test jsonString) {

    //do business logic
    return test;
}

@RequestBody - 将Json对象隐藏到java

@RequestBody -Covert Json object to java

@ResponseBody - 将Java对象转换为json

@ResponseBody - convert Java object to json
