JSONObject

 JSONObject paramJson = JSONObject.parseObject(param);
        if (!paramJson.containsKey("peerTime")) {
            throw new BaseException(ErrorCodeEnum.CODE_DB_CONNECT_ERROR, "set peer param must contains param peerTime");
        }

数组
"statisticsInfo": [{
        "idType": 0,
        "id": "1234567"
    },{
        "idType": 1,
        "id": "1234567"
    }]

List<JSONObject> statisticsInfoJson = JSONArray
        .parseArray((paramJson.get("statisticsInfo")).toString(), JSONObject.class);
List<StatisticsIdEntity> statisticsIds = new ArrayList<>(statisticsInfoJson.size());
for (JSONObject jsonObject : statisticsInfoJson) {
    StatisticsIdEntity statisticsIdEntity = new StatisticsIdEntity();
    statisticsIdEntity.setIdType(Short.valueOf(String.valueOf(jsonObject.get("idType"))));
    statisticsIdEntity.setIdValue(String.valueOf(jsonObject.get("id")));
    statisticsIds.add(statisticsIdEntity);
}

参数格式如下(areaCode是区域码,deviceId是点位id)

[{

       "areaCode": "12345",

       "deviceId": "12345"

},

{

       "areaCode": "12346",

       "deviceId": "12346"

}]

List<Map> areDeviceIds=JSONArray.parseArray(areaDeviceIds, Map.class)
