Embeddable entity with @OneToMany attribute

Question

Say, I have following entities:

@Entity
public class A {
  @Id
  @GeneratedValue
  private Long id;

  @Embedded
  private B b;

  //getters and setters
}
         


        

Answer 1

In general that is possible with @JoinColumn annotation. It works also with embeddables.

@OneToMany
@JoinColumn(name="A_ID")
private List<C> cList;

If you are not happy with A_ID name for column given in embeddable, you can override column name in entity A:

@AssociationOverride(name= "cList",
        joinColumns = @JoinColumn(name="SOME_NAME_FOR_JOIN_COLUMN_IN_TABLE_C"))
@Embedded
private B b;
