[eclipselink-users] Use an entity as a discriminator column
|
Hi,
I have some entities with an joined inheritance type. In my
root entity I have an attribute that is a @ManyToOne relationship to
other table. In short, my entity looks like this:
@Entity
@Inheritance(strategy = InheritanceType.JOINED)
@Table(name = "service")
public class Service implements Serializable {
@JoinColumn(name = "service_type_id", referencedColumnName = "id")
@ManyToOne
private ServiceType serviceTypeId;
....
The attribute serviceTypeId is a foreign key to other entity:
@Entity
@Table(name = "service_type")
public class TipoServicio implements Serializable {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Basic(optional = false)
@Column(name = "id")
private Integer id;
@Column(name = "name")
private String name;
......
I'd
like to have as DiscriminatorColumn the field serviceTypeId, but I
don't know how to do it, as that field hasn't a correct
discriminatorType. Is there any way to do what I want?
Thanks!
