GSON.fromJson（）问题与哈希图

Question

我正在使用GSON 2.5。

我有2个字符串：

字符串ReservationRoomNightGood =“ [{\\” reservationRoomNightParams \\“：{\\” date \\“：\\” 2016-06-05 \\“，\\” totalPrice \\“：600，\\” currencyCode \\“：\\” EUR \\“，\\ “crsRatePlanId \\”：0，\\ “rateplanId \\”：0}，\\ “roomNightExtra \\”：[]}，{\\ “reservationRoomNightParams \\”：{\\ “日期\\”：\\ “2016年6月6日\\”， \\ “totalPrice \\”：400，\\ “CURRENCYCODE \\”：\\ “EUR \\”，\\ “crsRatePlanId \\”：0，\\ “rateplanId \\”：0}，\\ “roomNightExtra \\”：[]}]“;

字符串ReservationRoomNightBad =“ [{\\” reservationRoomNightParams \\“：{\\” date \\“：\\” 2016-06-05 \\“，\\” totalPrice \\“：700，\\” currencyCode \\“：\\” EUR \\“，\\ “chRatePlanCodes \\”：{\\ “日期\\”：\\ “2016年6月5日\\”，\\ “totalPrice \\”：600，\\ “CURRENCYCODE \\”：\\ “EUR \\”，\\ “crsRatePlanId \\”：0， \\ “rateplanId \\”：0}，\\ “crsRatePlanId \\”：12969，\\ “configuredCommission \\”：0，\\ “configuredCommissionType \\”：\\ “P \\”，\\ “rateplanId \\”：0}，\\“roomNightExtra \\ “：[]}]”;

我有这个类来填充字符串到：

import java.io.Serializable;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

import org.apache.log4j.Logger;


public class ReservationRoomNight implements Serializable{

    private static final long serialVersionUID = -3697795946626268528L; 

    transient private static Logger logger = Logger.getLogger(Reservation.class);


    private List<ReservationExtraCost> roomNightExtra;

    private Map<String, String> reservationRoomNightParams;


    private Map<String, String> chRatePlanCodes = new HashMap<String, String>();


    private long crsRatePlanId;

    private Float configuredCommission;

    private String configuredCommissionType;

    public ReservationRoomNight(String nightDate, Float totalPrice, String currencyCode) {
        reservationRoomNightParams = new HashMap<String, String>();
        chRatePlanCodes = new HashMap<String, String>();
    }   
    public List<ReservationExtraCost> getRoomNightExtra() {
        return roomNightExtra;
    }
    public void setRoomNightExtra(List<ReservationExtraCost> roomNightExtra) {
        this.roomNightExtra = roomNightExtra;
    }

    public Map<String, String> getChRatePlanCodes() {
        return chRatePlanCodes;
    }

    public void setChRatePlanCodes(Map<String, String> chRatePlanCodes) {
        this.chRatePlanCodes = chRatePlanCodes;
    }

    public String getChannelCodes(String key) {
        return chRatePlanCodes.get(key);
    }

    public long getCRSRatePlanId() {
        return crsRatePlanId;
    }




}

毫无疑问，reservationRoomNightGood字符串提取出来，但我不知道为什么reserveRoomNightBad失败。

Type listType = new TypeToken<ArrayList<ReservationRoomNight>>() {}.getType();
        List<ReservationRoomNight> goodReservationRoomNight = new Gson().fromJson(reservationRoomNightGood, listType);
        List<ReservationRoomNight> boodReservationRoomNight = new Gson().fromJson(reservationRoomNightBad, listType);

如果我从ReservationRoomNightBad字符串中取出chRatePlanCodes哈希图，则没有问题。 但是，当我将字符串的那部分留在其中时会出现问题。例如，尝试使用此字符串运行它（reservationRoomNightBad-哈希图）

字符串ReservationRoomNightBad =“ [{\\” reservationRoomNightParams \\“：{\\” date \\“：\\” 2016-06-05 \\“，\\” totalPrice \\“：700，\\” currencyCode \\“：\\” EUR \\“，\\ “crsRatePlanId \\”：12969，\\ “configuredCommission \\”：0，\\ “configuredCommissionType \\”：\\ “P \\”，\\ “rateplanId \\”：0}，\\ “roomNightExtra \\”：[]}]“;

有任何想法吗？

您的代码：

private Map<String, String> reservationRoomNightParams;

只接受键字符串&&值字符串，但是您为该属性提供了一个对象：

"chRatePlanCodes":{
                "date":"2016-06-05",
                "totalPrice":600,
                "currencyCode":"EUR",
                "crsRatePlanId":0,
                "rateplanId":0
            }

使用以下方法解决此问题：

private Map<String, Object> reservationRoomNightParams;
