Hi Patrick,
My Subclasses have only the 'id' and the 'version' field of the superclass in
common, each has it own table and the tables primary key columns differ from
each other. So the subclasses inherit all the id attribute from the superclass,
but their corresponding column names differ.
@MappingSuperclass
public abstract class AbstractObject {
@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)
private Long id;
}
@Entity
@Table(name="events_course")
public class Course extends AbstractObject {
// the inherited attribute 'id' from AbstractObject is named 'course_id' in
// the table 'events_course'. How can I do that using annotations?
}
@Entity
@Table(name="events_customer")
public class Customer extends AbstractObject {
// the inherited attribute 'id' from AbstractObject is named 'customer_id'
// in the table 'events_customer'. How can I do that using annotations?
}
@Entity
@Table(name="events_booking")
public class Booking extends AbstractObject {
// the inherited attribute 'id' from AbstractObject is named 'booking_id'
// in the table 'events_booking'. How can I do that using annotations?
}
Thank you in advance!
Christian
