＜对象转List＜Map＜String,String＞＞＞Object转换jsonObject

案例一:
假设有一个对象数据如下:

{"data":{	"total": 100,"page":1,"size": 100,"record":[{"task":"startProduction","startTime":"2022-02-26","endTime":"2022-03-01","taskId":"aaa123"},{"task":"endProduction","startTime":"2022-02-26","endTime":"2022-03-01","taskId":"aaa123456"} ],}"code":200,"message":"success"
}

如何把record数组里面的数据取出来,塞到List<Map<String,String>>当中去;
直接上代码:

List<Map<String,String>> list = new ArrayList<>();
Result res = data;  // 假设data为上面对象中的数据
Object obj= res.getData();
JSONObject json = (JSONObject) JSONObject.toJSON(obj);  // 关键步骤
JSONArray jsonArray = json.getJSONArray("record");
if(jsonArray.size()>0) {for (int i = 0; i < jsonArray.size(); i++) {Map<String, Object> map = new HashMap<>();JSONObject job = jsonArray.getJSONObject(i);String task = String.valueOf(job.get("task"));String taskId= String.valueOf(job.get("taskId"));	map.put("task ",task );map.put("taskId",taskId);	list.add(map);}}    

案例二:

{"msg_id": "36010000000000221589792383034","device_id": "3601000000000022","device_type":"ZDK","event_time": "1589792383","type": "DEVICE_REPORT","data": {"subdev_id": "0101ec1bbdfffebb61c9","group_sid": "0101ec1bbdfffebb61c9","subdev_type": "0101ec1bbdfffebb61c9"}
}

当给你这一串东西的时候，后端应该怎么接受呢，不多说了，直接贴代码

@PostMapping(“/test”)
public Object test(@RequestBody Object object) {
JSONObject jsonObject = JSONObject.fromObject(object);
System.out.println(jsonObject.getJSONObject(“data”).getString(“subdev_id”));
return null;
}

重点在于第一句代码，转换
但是要引入一个jar包

net.sf.json-lib
json-lib
2.4
jdk15
