request receiving data servlet request json

The use of a alibaba fastjson: jar package for fastjson-1.2.7.jar

Reference: https://www.qingtingip.com/h_229797.html

Thinking: json Since this received data format is: { "list": [{ "tHumidity": 0, "tLightIntensity": 0, "tTemperature": 0, "tSerialNumber": "02001"}, { ". .........]}

　　　I.e., {key: value (value array)}, need to extract the value, type value is JSONArray, then traverse the array of value, and then converted by a strong JSONObject

　　　Whereby the array element read json keys.

　　　　 JSONObject json= new JSONObject();
        JSONArray list = new JSONArray();
        BufferedReader br;
        String jsonStr = null;
        String jsonStr2 = null;
        try {
            br = new BufferedReader(new InputStreamReader((ServletInputStream) request.getInputStream()));
            String line = null;
            StringBuilder sb = new StringBuilder();

            while ((line = br.readLine()) != null) {
                sb.append(line);
            }
            json= JSONObject.parseObject(sb.toString());
            jsonStr = JSONObject.toJSONString(json);
            list = json.getJSONArray("list");
            jsonStr2 = JSONArray.toJSONString(list);


        } catch (IOException e) {
            e.printStackTrace();
        }
        System.out.println(json);
        System.out.println(list);
        //System.out.println(jsonStr.substring(0,jsonStr.length()-1));
        // System.out.println(jsonStr);

        System.out.println("======================");

//            List<MyClass> list = JSONObject.parseArray(jsonStr,  MyClass.class);
        for (int i = 0; i < list.size();i++){
            JSONObject object = (JSONObject)list.get(i);
//            System.out.println(object);
            Zhongyao zhongyao = new Zhongyao();
            zhongyao.setId(UUIDUtil.uuid());
            zhongyao.settSerialNumber(object.getString("tSerialNumber"));
            zhongyao.settTemperature((object.getDouble("tTemperature") == null) ? 0 :object.getDouble("tTemperature"));
            zhongyao.settHumidity((object.getDouble("tHumidity") == null) ? 0 : object.getDouble("tHumidity"));
            zhongyao.settLightIntensity((object.getDouble("tLightIntensity") == null) ? 0 : object.getDouble("tLightIntensity"));
            zhongyao.settSoilTemperature((object.getDouble("tSoilTemperature") == null) ? 0 :object.getDouble("tSoilTemperature"));
            zhongyao.settSoilHumidity((object.getDouble("tSoilHumidity") == null) ? 0 : object.getDouble("tSoilHumidity"));
            zhongyao.settSoilPh((object.getDouble("tSoilPh") == null) ? 0 : object.getDouble("tSoilPh"));
            //(json.getDouble("tSoilPh") == null)
            System.out.println("+++++++++++++id:"+zhongyao.getId()+"tSerialNumber:"+zhongyao.gettSerialNumber()+
                    "tTemperature:"+zhongyao.gettTemperature()+"tHumidity:"+zhongyao.gettHumidity()+"tLightIntensity:"+zhongyao.gettLightIntensity()
