JSON发布到Spring Controller

Question

嗨,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.我在HTTP-POST方面遇到了一些问题.我创建了一个方法:

@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;
}

我的模型Test看起来像:

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"},我总是得到错误;

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

我进口杰克逊库.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.

使用将JSON对象转换为JSON String

JSON.stringify({ "名": "测试名"})

或手动.@RequestBody期待json字符串而不是json对象.

注意:stringify函数有一些IE版本的问题,它会起作用

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

$.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
    }
});

调节器

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

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

    //do business logic
    return test;
}

@RequestBody -Cove Json对象到java

@ResponseBody - 将Java对象转换为json
