Hi I'm looking for the way to simplify entity made only from two id's.



This is wha I've done and its working but looks little bit ugly.
I hope there is a way to remove CompositeId as another class.



@Entity
@IdClass(CompositeId::class)
data class OnlyPrimaryKeyClass(
@Id
val id1: Int,
@Id
val id2: Int
)

data class CompositeId(
val employeeId: Int,
val organizationId: Int
) : Serializable
