GSON中解析JSON应该是我的类结构 [英] What should be my class structure to parse JSON in GSON

问题描述

我有以下JSON数据：

  {
response：{}，
 errorMessage：{
error：[
 {
errorId：260003，
domain：ads，
subdomain： asd，
severity：asd，
category：asd，
message：asdsa asd ad，
errorName：未经授权的
} 
] 
} 
} 
  

目前我有以下类结构：

  public class JSONCollection 
 private response response; 
私人ErrorMessage错误; 
 
 public class Response 
 private String collectionId; 
私人字符串网址; 
 
 public class ErrorMessage 
 private List< ErrorValues>错误; 
 
 public class ErrorValues 
 private String errorId; 
私人字符串域; 
私人字符串子域; 
私人字符串严重性; 
私有字符串类别; 
私人字符串消息; 
 private String errorName; 
  

我为所有私有变量设置了setters / get设置

但是，当我做一个 JSONCollection cJson = gson.fromJson（JSONValue，JSONCollection.class）; 我得到cJson作为 null 。

如何正确使用？

解决方案

我使用@JigarJoshi显示的此工具来生成我的模式。

我发现的唯一区别是我必须将类名从 ErrorValues 更改为 Error

I have the following JSON data:

{
    "response": {},
    "errorMessage": {
        "error": [
            {
                "errorId": 260003,
                "domain": "ads",
                "subdomain": "asd",
                "severity": "asd",
                "category": "asd",
                "message": "asdsa  asd ad",
                "errorName": "UnAuthorized"
            }
        ]
    }
}

Currently I have the following class structure:

public class JSONCollection
    private Response response;
    private ErrorMessage error;

public class Response 
    private String collectionId;
    private String url;

public class ErrorMessage 
    private List<ErrorValues> error;

public class ErrorValues 
    private String errorId;
    private String domain;
    private String subdomain;
    private String severity;
    private String category;
    private String message;
    private String errorName;

I have setters/get set for all private variables

But when I do a JSONCollection cJson = gson.fromJson(JSONValue,JSONCollection.class); I get cJson as a null.

How to get it right?

解决方案

I used this tool shown by @JigarJoshi to generate my schema.

The only difference I found is I had to change the class name from ErrorValues to Error
