Java代码将JSON转换为键值对中的文本 [英] java code to convert json into text in key value pair

问题描述

我是Java的新手，我想编写一个代码，将传入的json文件转换为键值对中的文本，将其用管道分隔. json文件中的架构倾向于更改.因此，我无法基于每个值(我之前尝试过)编写程序.

I am new to Java, I want to write a code which convert my incoming json file to text in key-value pair which will be pipe separated. The schema in json files tends to change. So I can't write a program based on each value (which I tried earlier).

有人可以帮忙吗?

推荐答案

我已经编写了一些将json字符串解析为map/list对象的方法.

I have written some methods to parse json string into map/list object.

public static Map<String,Object> parseJSONObjectToMap(JSONObject jsonObject) throws JSONException{
    Map<String, Object> mapData = new HashMap<String, Object>();
    Iterator<String> keysItr = jsonObject.keys();
        while(keysItr.hasNext()) {
            String key = keysItr.next();
            Object value = jsonObject.get(key);

            if(value instanceof JSONArray) {
                value = parseJSONArrayToList((JSONArray) value);
            }else if(value instanceof JSONObject) {
                value = parseJSONObjectToMap((JSONObject) value);
            }
            mapData.put(key, value);
        }
    return mapData;
}

public static List<Object> parseJSONArrayToList(JSONArray array) throws JSONException {
    List<Object> list = new ArrayList<Object>();
    for(int i = 0; i < array.length(); i++) {
        Object value = array.get(i);
        if(value instanceof JSONArray) {
            value = parseJSONArrayToList((JSONArray) value);
        }else if(value instanceof JSONObject) {
            value = parseJSONObjectToMap((JSONObject) value);
        }
        list.add(value);
    }
    return list;
}
