解析JSON的操作，多层JSON

Question

对JSON的key做处理；

需要把Key解析出来，拼起来做参数使用

解析后如下：data_是我自己加的，后面的按key的层级，进行拼接

1.value是单层的

data_brand,

data_category,

data_ip,......

2.value是多层的

data_unresolvedData_macAddress,

data_unresolvedData_system_systemBit

JSON如下：

{
    "brand": "server",
    "category": "server",
    "iP": "127.0.0.1",
    "isSave": "true",
    "isSaveRelation": "false",
    "localPort": "",
    "name": "test-app",
    "portID": "",
    "relations": {},
    "type": "server",
    "unresolvedData": {
        "macAddress": "1234567",
        "system": {
            "systemBit": "123",
            "systemType": "123",
            "UUID": "",
            "version": "123"
        },
        "ip": "127.0.0.1",
        "hardDisk": {
            "totalSize": "1GB",
            "usedSize": "1GB",
            "useableSize": "1GB"
        },
        "cpu": {
            "model": "qwertyp",
            "threadNum": "421",
            "cpuNum": "22",
            "totalCoreNum": "412",
            "coreNum": "22"
        },
        "subType": "test",
        "RAM": {
            "totalSlot": "",
            "maxCapacity": "1GB",
            "maximumCapacity": ""
        }
    }
}

方法

public static List parseJson(String str,JSONObject json,List list){
        Iterator<String> iterator =  json.keys();
        while(iterator.hasNext()){
            String key = iterator.next();
            String value = json.getString(key);
            JSONObject child = null;
            try {
                child = JSONObject.fromObject(value);
                parseJson(str + "_" + key,child,list);
            } catch (Exception e) {
                list.add(str + "_" + key);
            }
        }
        return list;
    }

调用

String str = "你的json";
JSONObject json = JSONObject.fromObject(str);
        List list = new ArrayList();
        parseJson("data",json,list);
        for(int i=0;i<list.size();i++){
            System.out.println(list.get(i));
        }
