MST151: СТРУКТУРА СТОЛА

enter image description here

Я хочу иметь идентификационные отношения, как показано на рисунке.

Вопросы: Я хочу отобразить ассоциации, такие как [структура MST151]. Однако, как я думал, при сопоставлении ассоциаций выдается ошибка.

Как должна быть сделана ассоциация в вышеуказанной структуре идентификации составного ключа?

Вы можете использовать встроенные ключи, как показано ниже: 

@Embeddable
public class Mst151Key implements Serializable {
  @Column(name = "ITEM_ID")
  private String itemId;

  @Column(name = "COMP_ID")
  private String compId;

  @Column(name = "PRICE_REV")
  private int priceRev;

  @Column(name = "PRICE_TYPE")
  private String priceType;

}

public class MST151 {
    @EmbeddedId
    private Mst151Key mst151Key;

    @Column(name = "PRICE_STD")
    private double priceStd;

    @Column(name = "PRICE_UNIT")
    private String priceUnit;

    @Column(name = "DELIVERY_TYPE")
    private String deliveryType;

    @Column(name = "DELIVERY_DAY")
    private int deleveryDay;

    @Column(name = "DESCRIPTION")
    private String description;

    @Column(name = "CREATE_USER")
    private String createUser;

    @Column(name = "CREATE_TIME")
    private Date createTime;

    @Column(name = "UPDATE_USER")
    private String updateUser;

    @Column(name = "UPDATE_TIME")
    private Date updateTime;

    @Column(name = "USED")
    private int used;

    @OneToOne(fetch = FetchType.LAZY, optional = false)
    @JoinColumn(name = "ITEM_ID", insertable = false, updatable = false)
    private MST110 mst110;

    @OneToOne(fetch = FetchType.LAZY, optional = false)
    @JoinColumn(name = "COMP_ID", insertable = false, updatable = false)
    private MST150 mst150;
}
