[eclipselink-users] Problems with mapping having @Id with @GeneratedValu

[Andreas Joseph Krogh <andreak@xxxxxxxxxxxx>]

Hi.

 

In Hibernate this inheritance-schema works (this is Scala-code but you get it):

@MappedSuperclass
abstract class AbstractDomainObject {
        @Id
        @Column(name = "id")
        @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "SEQ_STORE")
        var id: java.lang.Long = null
}

@Entity
@Table(name = "project")
@SequenceGenerator(name = "SEQ_STORE", sequenceName = "project_id_seq", allocationSize = 1)
class Project extends AbstractDomainObject

 

But in EL I get this exception:

Exception Description: Conflicting annotations with the same name [SEQ_STORE] were found. The first one [@javax.persistence.SequenceGenerator({sequenceName=rpm_user_id_seq, name=SEQ_STORE, allocationSize=1})] was found within [class no.officenet.example.rpm.support.domain.model.entities.User] and the second [@javax.persistence.SequenceGenerator({sequenceName=project_id_seq, name=SEQ_STORE, allocationSize=1})] was found within [class no.officenet.example.rpm.projectmgmt.domain.model.entities.Project]. Named annotations must be unique across the persistence unit.

 

 

The thing is that I have lots of entities inheriting from my AbstractDomainObject, which defines the @Id, but the sequence to use is defined in the child-entities because it's table-specific. I'd rather not define the @Id in all my child-entities.

 

Is there a way to accomplish this in EL?

 

Thanks.
