How to map one class to different tables using hibernate/jpa annotations

Question

I\'m currently stuck with what seems to be a very simple problem, but I just can\'t seem to find a way around:

I have 2 identical tables:

1. tb

Answer 1

Using @MappedSuperclass, you would proceed as follows:

@MappedSuperclass
public class Transaction ...

@Entity
@Table(name="tbl_creditcard_approved_txns")
public class DeclinedTransaction extends Transaction ...

@Entity
@Table(name="tbl_creditcard_declined_txns")
public class ApprovedTransaction extends Transaction ...

Use @AttributeOverride to override column names between the two types of Transaction objects, if needed.

Update: I see that you want to map one @Entity to two tables in the same EntityManagerFactory ... I don't think you can do that.
