Hi
I have an entity like

@Entity
public class Customer
{

@ID
@column(name="CustomerID")
private int customerID;

@column(name="CustID")
private int custID;

}

where customerID is a primary key column and hence it is annotated with Id
and custID is just another column

Requirement is that when customer object is persisted, customerID and custID should have the same value. Now, generation of ID is left to JPA.

How can i set CustID with the same value as CustomerID in a single database trip? Is there any annotation which can help me achieve it?

Hi All,

@PrePersist did the job

Pretty easy approach. Should have thought of it even before posting the question
