java - 一对一多列外键的断列映射

Question

我有两个实体 RoomNight 和 BookingCorporateDetails，其中 BookingCorporateDetails 在两列(booking_id 和room_night_booking_id)。

BookingCorporateDetails 是可选的，但 RoomNight 是必需的。我正在尝试在 BookingCorporateDetails 表上创建一个外键连接 -

AbstractJpaEntity.java

@MappedSuperclass
@SuppressWarnings("serial")
public abstract class AbstractJpaEntity implements Serializable {

  @Id
  @GeneratedValue(strategy = GenerationType.IDENTITY)
  protected Long id;

  @Column(name = "created_at")
  @Temporal(TemporalType.TIMESTAMP)
  protected Date createdAt;

  @Column(name = "created_by", length = 32, nullable = true)
  protected String createdBy;

  @Column(name = "updated_at")
  @Temporal(TemporalType.TIMESTAMP)
  protected Date updatedAt;

  @Column(name = "updated_by", length = 32, nullable = true)
  protected String updatedBy;

  @Column(name = "is_published", columnDefinition = "tinyint(1) default 1")
  protected boolean isPublished;

  @Column(name = "is_deleted", columnDefinition = "tinyint(1) default 0")
  protected boolean isDeleted;

  // Getters and Setters
}

AbstractBookingEntity.java

@MappedSuperclass

  @Column(name = "room_night_booking_id", nullable = false)
  protected String roomNightBookingId;

  public String getBookingId() {
    return bookingId;
  }

  public void setBookingId(String bookingId) {
    this.bookingId = bookingId;
  }

  public String getRoomNightBookingId() {
    return roomNightBookingId;
  }

  public void setRoomNightBookingId(String roomNightBookingId) {
    this.roomNightBookingId = roomNightBookingId;
  }
}

BookingCorporateDetailsEntity.java

  })
  private RoomNightEntity roomNightEntity;

  public RoomNightEntity getRoomNightEntity() {
    return roomNightEntity;
  }

  public void setRoomNightEntity(RoomNightEntity roomNightEntity) {
    this.roomNightEntity = roomNightEntity;
  }

  // Getters And Setters
}

RoomNightEntity.java

@Entity(name = "room_night")
@Table(name = "room_night", uniqueConstraints = { @UniqueConstraint(name = "key_rm_order_sub_order", columnNames = { "booking_id", "room_night_booking_id" }) })
public class RoomNightEntity extends AbstractBookingEntity {

  @Column(name = "ota_booking_id", nullable = false)
  private String otaBookingId;

  @Column(name = "property_id", nullable = false)
  private Long propertyId;

  @Column(name = "room_type_id", nullable = false)

  @Column(name = "booking_status", nullable = false)
  private Integer bookingStatus;

  @Column(name = "occupancy", nullable = false)
  private Integer occupancy;

  @Column(name = "user_id", nullable = false)
  private Long userId;

  @Column(name = "payment_mode", nullable = false)
  private String paymentMode;

  @Column(name = "stay_date")
  @Temporal(TemporalType.DATE)
  private Date stayDate;

  @OneToOne(cascade = CascadeType.ALL, mappedBy = "roomNightEntity", fetch = FetchType.LAZY)
  private BookingCorporateDetailsEntity bookingCorporateDetailsEntity;

  // Getters and Setters
}

当我执行代码时，出现以下异常 -

PS:我已经在这里看到了多个示例，但即使尝试了这些解决方案也无法解决问题。

我做了一些测试，它与两个连接列一起工作的唯一方法是从 RoomNightEntity 实体中删除 mappedBy。

你最终得到了一种没有父子关系的双向映射:BookingCorporateDetailsEntity

@OneToOne(optional = true, cascade = CascadeType.ALL, fetch = FetchType.EAGER)
@JoinColumns({
          @JoinColumn(name = "booking_id", referencedColumnName = "booking_id", insertable = false, updatable = false),
            @JoinColumn(name = "room_night_booking_id", referencedColumnName = "room_night_booking_id", insertable = false, updatable = false)
    })
private RoomNightEntity roomNightEntity;

RoomNightEntity

@OneToOne(cascade = CascadeType.ALL, fetch = FetchType.LAZY)
@JoinColumns({
            @JoinColumn(name = "booking_id", referencedColumnName = "booking_id", insertable = false, updatable = false),
            @JoinColumn(name = "room_night_booking_id", referencedColumnName = "room_night_booking_id", insertable = false, updatable = false)
    })
private BookingCorporateDetailsEntity bookingCorporateDetailsEntity;
