Question

我使用的是GSON 2.5。

我有2个字符串：

String reservationRoomNightGood =   ＆＃34; [{\＆＃34; reservationRoomNightParams \＆＃34;：{\＆＃34;日期\＆＃34;：\＆＃34; 2016年6月5日\＆＃34; \＆＃ 34; totalPrice \＆＃34;：600，\＆＃34; CURRENCYCODE \＆＃34;：\＆＃34; EUR \＆＃34; \＆＃34; crsRatePlanId \＆＃34;：0，\ ＆＃34; rateplanId \＆＃34;：0}，\＆＃34; roomNightExtra \＆＃34;：[]}，{\＆＃34; reservationRoomNightParams \＆＃34;：{\＆＃34;日期\＆＃34;：\＆＃34; 2016年6月6日\＆＃34; \＆＃34; totalPrice \＆＃34;：400，\＆＃34; CURRENCYCODE \＆＃34;：\＆＃34; EUR \＆＃34; \＆＃34; crsRatePlanId \＆＃34;：0，\＆＃34; rateplanId \＆＃34;：0}，\＆＃34; roomNightExtra \＆＃34; ：[]}]＆＃34 ;;

String reservationRoomNightBad =   ＆＃34; [{\＆＃34; reservationRoomNightParams \＆＃34;：{\＆＃34;日期\＆＃34;：\＆＃34; 2016年6月5日\＆＃34; \＆＃ 34; totalPrice \＆＃34;：700，\＆＃34; CURRENCYCODE \＆＃34;：\＆＃34; EUR \＆＃34; \＆＃34; chRatePlanCodes \＆＃34;：{\＆＃34;日期\＆＃34;：\＆＃34; 2016年6月5日\＆＃34; \＆＃34; totalPrice \＆＃34;：600，\＆＃34; CURRENCYCODE \＆＃34 ;：\＆＃34; EUR \＆＃34; \＆＃34; crsRatePlanId \＆＃34;：0，\＆＃34; rateplanId \＆＃34;：0}，\＆＃34; crsRatePlanId \ ＆＃34;：12969，\＆＃34; configuredCommission \＆＃34;：0，\＆＃34; configuredCommissionType \＆＃34;：\＆＃34; p \＆＃34; \＆＃34; rateplanId \＆＃34;：0}，\＆＃34; roomNightExtra \＆＃34;：[]}]＆＃34 ;;

我有这个类将字符串填充到：

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;
    }




}

提取reservationRoomNightGood字符串没问题，但我无法弄清楚为什么reservationRoomNightBad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 hashmap，我没有问题。但是，当我留下该部分字符串时会出现问题。例如，尝试使用此字符串运行它（reservationRoomNightBad - hashmap）

String reservationRoomNightBad = ＆＃34; [{\＆＃34; reservationRoomNightParams \＆＃34;：{\＆＃34;日期\＆＃34;：\＆＃34; 2016年6月5日\＆＃34; \＆＃ 34; totalPrice \＆＃34;：700，\＆＃34; CURRENCYCODE \＆＃34;：\＆＃34; EUR \＆＃34; \＆＃34; crsRatePlanId \＆＃34;：12969，\ ＆＃34; configuredCommission \＆＃34;：0，\＆＃34; configuredCommissionType \＆＃34;：\＆＃34; p \＆＃34; \＆＃34; rateplanId \＆＃34;：0 }，\＆＃34; roomNightExtra \＆＃34;：[]}]＆＃34 ;;

有什么想法吗？

您的代码：

private Map<String, String> reservationRoomNightParams;

只接受键字符号＆amp;＆amp; value String，但是您为此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;

GSON.fromJson（）问题与hashmap
