Question

我在这里试图查找def callbackTo2(*args): screen_manager.current = 'main_screen' class ScreenOne(Screen): def __init__(self, *args): super(ScreenOne, self).__init__(name='ScreenOne') self.timer = None def on_enter(self, *args): print('on_enter ScreenOne:') # start the timer for 30 seconds self.timer = Clock.schedule_once(callbackTo2, 30) def on_leave(self, *args): # cancel the timer self.timer.cancel() self.timer = None def on_touch_down(self, touch): if self.timer is not None: self.timer.cancel() # reset the timer self.timer = Clock.schedule_once(callbackTo2, 30) return super(ScreenOne, self).on_touch_down(touch)和campStartDate之间的日期，但是我无法设置静态日期，我只是想获取campcampDate和camEndDate之间的日期

我已经尝试过了，但是我不知道如何以正确的方式获取数据：

campEndDate

CrudRepository类：

public class Bulk_repository {
@Id
   @GeneratedValue(strategy=GenerationType.AUTO)
   @Column(name = "id")
   private long id;

   @Column(name = "camp_start_date")   
   private Date campStartDate;

   @Column(name = "camp_end_date")
   private Date campEndDate;
}

应用程序：

public interface Bulk_repositoryRepository extends CrudRepository<Bulk_repository, Long> {

List<Bulk_repository>findAllByStatusAndCampTypeAndCampStartDateLessThanEqualAndCampEndDateGreaterThanEqual(int status, int campType,Date campStartDate,Date campEndDate);
Bulk_repository findById(long id);
}

Answer 1

考虑 campStartDate 总是小于 campEndDate ，如果您要查找某个日期的记录，而该日期的日期介于两者之间，认为比较不正确，应按如下所示更改条件

public interface Bulk_repositoryRepository extends CrudRepository<Bulk_repository, Long> {

List<Bulk_repository>findAllByStatusAndCampTypeAndCampStartDateGreaterThanEqualAndCampEndDateLessThanEqual(int status, int campType,Date campStartDate,Date campEndDate);
Bulk_repository findById(long id);
}

编辑：

如果您不想传递日期，那么JPQL可以为您提供帮助，请尝试更改存储库中的方法签名，例如

public interface Bulk_repositoryRepository extends CrudRepository<Bulk_repository, Long> {

@Query("SELECT b FROM Bulk_repository b WHERE b.status = :status and b.campStartDate >=CURRENT_DATE and b.campEndDate <= CURRENT_DATE)
List<Bulk_repository>findAllByStatusAndCampTypeAndCampStartDateGreaterThanEqualAndCampEndDateLessThanEqual(@Param("status") int status);
Bulk_repository findById(long id);

}

在2个日期之间查找日期
