@Entity
@Table(name="seance")
@Data
public class Seance {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(nullable = false, unique = true)
private Integer id;
private java.time.LocalTime displayTime;
@ManyToMany(mappedBy = "seances")
@JsonIgnore
private List<Repertoire> repertoires = new ArrayList<>();
@OneToMany(mappedBy = "reservationSeance", cascade = CascadeType.ALL, fetch = FetchType.LAZY)
@JsonIgnore
private List<Reservation> reservations = new ArrayList<>();
}
@Entity
@Table(name="reservation")
@Data
public class Reservation {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(nullable = false, unique = true)
private Integer id;
private java.time.LocalDate reservationDate;
@ManyToOne(fetch = FetchType.LAZY, cascade = CascadeType.ALL)
@JoinColumn(name = "id_seance")
private Seance reservationSeance;
.........
}
我有两个与ManyToOne有关的实体,我尝试扩展JpaRepository
public interface ReservationRepository extends JpaRepository<Reservation,Integer> {
List<Reservation> findReservationsByReservationSeance(Seance seance);
}
但是作为参数,我必须使用所有对象Seance,是否可以使用JpaRepository仅通过Seance表中的id和displayTime查找保留,还是需要编写自己的方法?

您可以在ReservationRepository
@Query("SELECT r FROM Reservation r WHERE r.reservationSeance.id=:seanceId AND r.reservationSeance.displayTime = :displayTime")
public List<Reservation> findReservations(@Param("seanceId") int seanceId, @Param("displayTime") LocalTime displayTime);
