在java中有段json字符串"{ "code":"000", "message":"成功", "data":[ { "flightId":1831011951, "flightDate":"2023-05-3000:00:00", "flightNo":"5101", "departCode":"SHA", "arriveCode":"PEK", "carrier":"MU", "flightStatus":"CALLING", "planDepartTime":"2023-05-3008:00:00", "planArriveTime":"2023-05-3010:15:00", "createTime":"2023-05-2413:35:58", "flightType":"CRE", "source":"MANUAL" } ], "success":true }"现在只要获取其中data里面的值，并且添加到 List<NotifyInfoCCResp>集合中，将完整代码展示出来

假设你已经定义好了 NotifyInfoCCResp 类，可以使用 Gson 库将 JSON 字符串转换成 Java 对象，然后取出 data 中的值，添加到 List<NotifyInfoCCResp> 集合中。代码如下：

import com.google.gson.Gson;
import com.google.gson.reflect.TypeToken;

import java.lang.reflect.Type;
import java.util.ArrayList;
import java.util.List;

public class Test {

    public static void main(String[] args) {
        String json = "{ \"code\":\"000\", \"message\":\"成功\", \"data\":[ { \"flightId\":1831011951, \"flightDate\":\"2023-05-3000:00:00\", \"flightNo\":\"5101\", \"departCode\":\"SHA\", \"arriveCode\":\"PEK\", \"carrier\":\"MU\", \"flightStatus\":\"CALLING\", \"planDepartTime\":\"2023-05-3008:00:00\", \"planArriveTime\":\"2023-05-3010:15:00\", \"createTime\":\"2023-05-2413:35:58\", \"flightType\":\"CRE\", \"source\":\"MANUAL\" } ], \"success\":true }";

        Gson gson = new Gson();
        Type type = new TypeToken<Response>() {}.getType();
        Response response = gson.fromJson(json, type);

        List<NotifyInfoCCResp> notifyInfoList = new ArrayList<>();
        for (NotifyInfo notifyInfo : response.getData()) {
            NotifyInfoCCResp notifyInfoCCResp = new NotifyInfoCCResp();
            notifyInfoCCResp.setFlightId(notifyInfo.getFlightId());
            notifyInfoCCResp.setFlightDate(notifyInfo.getFlightDate());
            notifyInfoCCResp.setFlightNo(notifyInfo.getFlightNo());
            notifyInfoCCResp.setDepartCode(notifyInfo.getDepartCode());
            notifyInfoCCResp.setArriveCode(notifyInfo.getArriveCode());
            notifyInfoCCResp.setCarrier(notifyInfo.getCarrier());
            notifyInfoCCResp.setFlightStatus(notifyInfo.getFlightStatus());
            notifyInfoCCResp.setPlanDepartTime(notifyInfo.getPlanDepartTime());
            notifyInfoCCResp.setPlanArriveTime(notifyInfo.getPlanArriveTime());
            notifyInfoCCResp.setCreateTime(notifyInfo.getCreateTime());
            notifyInfoCCResp.setFlightType(notifyInfo.getFlightType());
            notifyInfoCCResp.setSource(notifyInfo.getSource());
