我正在尝试创建两个实体,其中两个实体都有embeddedIds.其中一个实体有2个引用另一个实体,其中这两个引用都与ManyToOne相关.

  private String itemId;
  @Column(name = "item_client_id", nullable = false)
  private int clientId; 
  ...
}

@Entity
@Table(name = "item")
public class Item {
  @EmbeddedId
  private ItemPK id;

  @ManyToOne
  @JoinColumn(name = "item_client_id")
  private Client client;

  @OneToMany(mappedBy="item", cascade = CascadeType.ALL, orphanRemoval = true)
  private Set<RelatedItem> relatedItems;

  @OneToMany(mappedBy="relatedItem", cascade = CascadeType.ALL, orphanRemoval = true)
  private Set<RelatedItem> relatedItemsRHS;
  ...
}

@Embeddable
public class RelatedItemPK {
  @Column(name = "itemId", length = 100, nullable …
