对象 - 无法解析的日期

我有以下的JSON数据 -对象 - 无法解析的日期

我试图解析为以下Java类（ES） -

public class CRMAccount { 
    private String AccountID; 
    private String CRMId; 
    private String Name; 
    private CRMActivity LastActivity; 
    private String Owner; 
    private double Latitude; 
    private double Longitude; 
    private String AppointmentType; 
    private String RelationshipType; 
    private int Status; 

    public String getID() { 
     return AccountID; 
    } 

    public void setID(String accountID) { 
     AccountID = accountID; 
    } 

    public String getName() { 
     return Name; 
    } 

    public void setName(String name) { 
     Name = name; 
    } 

    public CRMActivity getLastActivity() { 
     return LastActivity; 
    } 

    public void setLastActivity(CRMActivity lastActivity) { 
     LastActivity = lastActivity; 
    } 

    public String getOwner() { 
     return Owner; 
    } 

    public void setOwner(String owner) { 
     Owner = owner; 
    } 

    public String getAppointmentType() { 
     return AppointmentType; 
    } 

    public void setAppointmentType(String appointmentType) { 
     AppointmentType = appointmentType; 
    } 

    public String getRelationshipType() { 
     return RelationshipType; 
    } 

    public void setRelationshipType(String relationshipType) { 
     RelationshipType = relationshipType; 
    } 

    public double getLatitude() { 
     return Latitude; 
    } 

    public void setLatitude(double latitude) { 
     Latitude = latitude; 
    } 

    public double getLongitude() { 
     return Longitude; 
    } 

    public void setLongitude(double longitude) { 
     Longitude = longitude; 
    } 

    public String getCRMId() { 
     return CRMId; 
    } 

    public void setCRMId(String cRMId) { 
     CRMId = cRMId; 
    } 
} 


public class CRMActivity { 
    private String Type; 
    private String Subject; 
    private String RegardingObjectType; 
    private Date StartTime; 
    private Date EndTime; 

    public CRMActivity(String type, Date dtEndTime, 
      Date dtStartTime, String subject) 
    { 
     this.Type = type; 
     this.Subject = subject; 
     this.StartTime = dtStartTime; 
     this.EndTime = dtEndTime; 
     this.RegardingObjectType = "account";  
    } 

    public String getType() { 
     return Type; 
    } 
    public void setType(String eventType) { 
     Type = eventType; 
    } 

    public String getSubject() { 
     return Subject; 
    } 
    public void setSubject(String subject) { 
     Subject = subject; 
    } 

    public String getRegardingObject() 
    { 
     return RegardingObjectType; 
    } 

    public Date getStartTime() { 
     return StartTime; 
    } 
    public void setStartTime(Date startTime) { 
     StartTime = startTime; 
    } 

    public Date getEndTime() { 
     return EndTime; 
    } 
    public void setEndTime(Date endTime) { 
     EndTime = endTime; 
    } 
}

这是我使用解析JSON数据的代码 -

Gson gson = new GsonBuilder().setDateFormat(DateFormat.FULL, DateFormat.FULL).create(); 
    CRMAccount[] lstCRMAccounts = gson.fromJson(serviceResponse.getResultMessage(),CRMAccount[].class);

这是从logcat的输出 -

我已经搜索并获得[this]（http://stackoverflow.com/questions/7816586/gson-java-text-parseexception-unparseable-date）和[this]（http://stackoverflow.com/问题/ 5845822/GSON - 解串键 - 值对自定义对象）。但这些都没有与我的格式相同的“JSON”数据。 –

更改日期数据类型为字符串，因为您的数据不在正确的合法位置 – Nand

谢谢，我没有用正确的“参数”搜索。我认为[this]（http://stackoverflow.com/questions/5671373/unparseable-date-1302828677828-trying-to-deserialize-with-gson-a-millisecond?rq=1）链接将会有所帮助。 –

我会使用自定义的反序列化器，因为你有日期解析的问题，也因为你的类没有无参数的构造函数。我将我的例子仅限于CRMActivity课程。

public class CustomDeserializer implements JsonDeserializer<CRMActivity> { 

    public CRMActivity deserialize(JsonElement json, Type typeOfT, 
      JsonDeserializationContext context) throws JsonParseException { 

     if (json == null) 
      return null; 

     JsonObject jo = json.getAsJsonObject(); 

     String type = jo.get("Type").getAsString(); 
     String subject = jo.get("Subject").getAsString(); 
     String endTimeAsString = jo.get("EndTime").getAsString(); 
     String startTimeAsString = jo.get("StartTime").getAsString(); 

     startTimeAsString = startTimeAsString.replace("/Date(", "").replace(")/", ""); 
     endTimeAsString = endTimeAsString.replace("/Date(", "").replace(")/", ""); 

     return new CRMActivity(type, new Date(Long.valueOf(startTimeAsString)), 
       new Date(Long.valueOf(endTimeAsString)), subject); 

    }

，并调用它是这样的：

public class Q19657666 { 

    /** 
    * @param args 
    */ 
    public static void main(String[] args) { 
     GsonBuilder gb = new GsonBuilder(); 
     gb.registerTypeAdapter(CRMActivity.class, new CustomDeserializer()); 

     Gson g = gb.create(); 

     String json = "{\"__type\": \"CRMService.Activity\","+ 
     "\"Subject\": \"Call back to understand the problem (sample)\", "+ 
     "\"Type\": \"Phone Call\", "+ 
     "\"RegardingObjectType\": \"account\","+ 
     "\"RegardingObjectId\": \"f3259a52-672f-e311-a7d8-d89d6765b134\","+ 
     "\"EndTime\": \"/Date(1381226400000)/\","+ 
     "\"Id\": \"50b79458-672f-e311-a7d8-d89d6765b134\","+ 
     "\"StartTime\": \"/Date(1381226400000)/\"}"; 

     CRMActivity crmActivity = g.fromJson(json, CRMActivity.class); 

     System.out.println(crmActivity); 
    } 

}

你会得到这样的结果：

CRMActivity [类型=电话，主题=回拨了解问题（示例），RegardingObjectType = account，StartTime = Tue Oct 08 12:00:00 CEST 2013，EndTime = Tue Oct 08:00:00 CEST 2013]
