JSON和XML的日期返回不同

Question

我正在使用Postman模拟我在Java到MYSQL数据库中创建的方法的API调用。

当我以JSON格式发送GET请求时，结果运行良好。但是，对于XML格式的相同方法，日期不会返回。逻辑和路径查询似乎很好，因为我能够以JSON格式获取完整列表。但是我缺少XML中的日期。

感谢任何人都可以指出我所缺少的东西。让我知道您是否需要其他信息。

这是不同收益的快照。

型号 PickUpLocationModel

 @XmlRootElement(name = "pickuplocation")
    public class PickUpLocationModel {
        @XmlElement(name = "id")
        public int Id;
        @XmlElement(name = "userId")
        public int UserId;
        @XmlElement(name = "lattitude")
        public double Lattitude;
        @XmlElement(name = "longitude")
        public double Longitude;
        @XmlElement(name = "locationame")
        public String LocationName;
        @XmlElement(name = "dateadded")
        public Date DateAdded;
        @XmlElement(name = "category")
        public String Category;

    }

PagedPickUpLocationsModel

@XmlRootElement(name  = "pickuplocations")
public class PagedPickUpLocationsModel {
    @XmlElement(name = "data")
    public ArrayList<PickUpLocationModel> Data;
    @XmlElement(name = "next")
    public String Next;
    @XmlElement(name = "prev")
    public String Prev;

    public PagedPickUpLocationsModel() {
        Data = new ArrayList<PickUpLocationModel>();
        Next = "";
        Prev = "";
    }
}

路径

@GET
    @Path("{user_id}/pickuplocations")
    @Produces({"application/json;qs=0.9","application/xml;qs=0.1"}) 
    public Response GetAllByUser(@PathParam("user_id") int userId, 
            @QueryParam("page") int pageNumber, 
            @QueryParam("pagesize") int pageSize) {

        PagedPickUpLocationsModel locations = pickUpLocationService.GetPickUpLocationsByUser(userId, pageNumber, pageSize);

        return Response.ok().entity(new GenericEntity<PagedPickUpLocationsModel>(locations) {}).build();
    }

逻辑

public ArrayList<PickUpLocationModel> GetPickUpLocationsByUser(int user_id, int page, int pageSize) {
        ArrayList<PickUpLocationModel> locations = new ArrayList<PickUpLocationModel>();

        int startFrom = (page - 1) * pageSize;

        Connection conn = DataConnection.GetConnection();

        try {
            PreparedStatement stmt = conn.prepareStatement("SELECT * FROM user_pickup_locations WHERE user_id = ? LIMIT ?,?");
            stmt.setInt(1, user_id);
            stmt.setInt(2, startFrom);
            stmt.setInt(3, pageSize);

            ResultSet result = stmt.executeQuery();

            while(result.next()) {
                PickUpLocationModel location = new PickUpLocationModel();
                location.Id = result.getInt("id");
                location.UserId = result.getInt("user_id");
                location.Lattitude = result.getDouble("lattitude");
                location.Longitude = result.getDouble("longitude");
                location.LocationName = result.getString("location_name");
                location.DateAdded = result.getDate("date_added");
                location.Category = result.getString("category");

                locations.add(location);
            }

        } catch (Exception e) {

            e.printStackTrace();

        }

        return locations;
    }
