日期范围之间的 Spring Data JPA 返回 null

Question

我正在使用原生查询来查询运算符之间的日期，但它返回 null。 当我用静态日期运行它时

@Query(value ="SELECT  a.name,m.title  from meetings m ,attendies a where m.id =a.m_aid and (start_time BETWEEN '2021-04-03 11:00:16' AND '2021-04-03 11:30:15' )",nativeQuery = true)
public List<Object[]> findConflictMettinds( Date startTime, Date endTime );

能够获取数据，但是当尝试使用动态值返回时，它总是返回 null。 以下是我目前尝试过的不同方法

@Query(value ="SELECT  a.name,m.title  from meetings m ,attendies a where m.id =a.m_aid and (m.start_time BETWEEN ?1 AND ?2 )",nativeQuery = true)
public List<Object[]> findConflictMettinds(@Param("startTime") Date startTime,@Param("endTime") Date endTime );                                          @Query(value ="SELECT  a.name,m.title  from meetings m ,attendies a where m.id =a.m_aid and (m.start_time BETWEEN :startTime AND :endTime )",nativeQuery = true)
public List<Object[]> findConflictMettinds(@Param("startTime") Date startTime,@Param("endTime") Date endTime );

Answer 1

@Query(value ="SELECT  a.name,m.title  from meetings m ,attendies a where m.id =a.m_aid and (m.start_time > :startTime AND m.start_time <:endTime )",nativeQuery = true)
public List<Object[]> findConflictMettinds(@Param("startTime") String startTime,@Param("endTime") String endTime );

SimpleDateFormat dateFormatter = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");

repository.findConflictMettinds(dateFormatter.format(startTime), dateFormatter.format(endTime))

您也不必使用本机查询，但如果有必要，您可以使用给定的示例。也可以找Search records between two dates using Spring Data JPA native query?

Answer 2

尝试将日期字符串作为模型属性而不是参数传递

public List<Object[]> findConflictMettinds(@ModelAttribute("startTime") String startTime,@ModelAttribute("endTime") String endTime );
