我也是参考了这个作者。顶他

public static JSONObject changeJsonObj(JSONObject jsonObj, List keyMap ,String FatherName) {
    JSONObject resJson = new JSONObject();
    Set keySet = jsonObj.keySet();
    for (String key : keySet) {
       // String resKey = keyMap.get(key) == null ? key : keyMap.get(key);
        String resKey =resultKey(keyMap,key,FatherName) == null ? key : resultKey(keyMap,key,FatherName);
        try {
            JSONObject jsonobj1 = jsonObj.getJSONObject(key);
            resJson.put(resKey, changeJsonObj(jsonobj1, keyMap,key));
        } catch (Exception e) {
            try {
                JSONArray jsonArr = jsonObj.getJSONArray(key);
                resJson.put(resKey, changeJsonArr(jsonArr, keyMap,key));
            } catch (Exception x) {
                    resJson.put(resKey, jsonObj.get(key));
            }
        }
    }
    return resJson;
}

public static JSONArray changeJsonArr(JSONArray jsonArr, List keyMap,String clienteleFatherNode) {
    JSONArray resJson = new JSONArray();
    for (int i = 0; i < jsonArr.size(); i++) {
        JSONObject jsonObj = jsonArr.getJSONObject(i);
        resJson.add(changeJsonObj(jsonObj, keyMap,clienteleFatherNode));
    }
    return resJson;
}

  private static List  result( List keyMap){
            TestVO test1=new TestVO();
        test1.setConversionName("XingMing");
        test1.setOriginalFatherName("user");
        test1.setOriginalName("name");
        TestVO test2=new TestVO();
        test2.setConversionName("YongHu");
        test2.setOriginalFatherName("");
        test2.setOriginalName("user");
        TestVO test3=new TestVO();
        test3.setConversionName("MiaoShu");
        test3.setOriginalFatherName("hobby");
        test3.setOriginalName("desc");
        TestVO test4=new TestVO();
        test4.setConversionName("dengyan");
        test4.setOriginalFatherName("user");
        test4.setOriginalName("desc");
        TestVO test5=new TestVO();
        test5.setConversionName("DY");
        test5.setOriginalFatherName("");
        test5.setOriginalName("desc");
        keyMap.add(test3);
        keyMap.add(test2);
        keyMap.add(test1);
        keyMap.add(test4);
        keyMap.add(test5);
        return keyMap;
    }
public static void main(String[] args) {
    String jsonStr = "{\"user\":{\"name\":\"张三\",\"desc\":\"就是这么任性\",\"sex\":\"男\",\"hobby\":[{\"motion\":\"足球\",\"desc\":\"任性\"},{\"game\":\"英雄联盟\",\"desc\":\"就是这么任性\"}]},\"desc\":\"aaaaaaa\"}";
   List keyMap=new ArrayList<>();
    keyMap =result(keyMap);

    JSONObject jsonObj = JSONObjectConversionUtil.changeJsonObj(JSONObject.parseObject(jsonStr),keyMap,"");
    System.out.println("换值结果 》》 " + jsonObj.toString());
    }

 

 

public class TestVO {
        //原来的父类名
    private String originalFatherName;
//需要转化的名称
    private String ConversionName;


//原来的名称
    private String originalName;

}
