Несоответствие данных между ответом Json и базой данных

Question

Я извлекаю данные из mysql, используя весеннюю загрузку, режим гибернации, и выдаю ответ в качестве службы REST.Но при проверке в Postman данные не совпадают.Вот мой код.

Класс контроллера:

@RestController
public class NotificationController<T> extends RestUtils<T> {
    @Autowired
    NotificationService<T> service;

    @RequestMapping(value = "/notification/getNotifications", method = RequestMethod.POST, headers = "Accept=application/json")
    public @ResponseBody Object getNotifications(@RequestBody NotificationBean notificationBean) {
        try {
            return getSuccessResponse(service.getNotifications(notificationBean), "Total Count: ",
                    service.getNotificationsCount(notificationBean));
        } catch (StudawnException e) {
            return getErrorResponse(e.getMessage());
        }
    }
}

Реализация сервиса:

@Service
public class NotificationServiceImpl<T> implements NotificationService<T> {
    @Autowired
    NotificationRepository notificationRepository;

    @SuppressWarnings("deprecation")
    @Transactional
    @Override
    public Object getNotifications(NotificationBean notificationBean) throws StudawnException {
        Sort sort = new Sort(new Sort.Order(Direction.DESC, "dateCreated"));
        Pageable pageable = new PageRequest(notificationBean.getPage(), notificationBean.getSize(), sort);
        return notificationRepository.findNotificationsByStudentId(notificationBean.getStudentId(), pageable);
    }

}

Репозиторий:

@Repository
public interface NotificationRepository<T> extends JpaRepository<Notification, Integer> {
    @Query(NotificationQuery.findNotificationsByStudentId)
    List<Notification> findNotificationsByStudentId(@Param("studentId") Integer studentId, Pageable pageable);

    @Query(NotificationQuery.findNotificationsCountByStudentId)
    Integer findNotificationsCountByStudentId(@Param("studentId")Integer studentId);
}

Класс запроса:

public class NotificationQuery {
    public static final String findNotificationsByStudentId = "select n from #{#entityName} n where n.student.studentId = :studentId and n.isActive=true";
    public static final String findNotificationsCountByStudentId = "select count(n) from #{#entityName} n where n.student.studentId=:studentId and n.isActive=true";
}

Запрос Json

{

Ответ Json Дата в поле dateCreated не соответствует базе данных.Фактическая дата в БД - «2018-03-06», но в ответ «2018-03-05»

Заранее спасибо.

Я думаю, вы должны проверить часовые пояса. Похоже, вы сохранили дату в местном часовом поясе, но когда вы извлекаете ее из базы данных и отправляете клиенту, вы используете часовой пояс GMT.
