Question

I want to use existing database. Entity table has a column named code to be used as primary key.

Probably a simple annotation but I am new to Play Framework and JPA.

Thank you

Answer 1

Well actually might not be that straightforward if you are new to play framework.

Play uses the Model class which extends GenericModel which in turn extends JPABase.
The model class enhances the entity with it’s own Id.

So if your entity has it’s own primary key, have it extend GenericModel and define your primary key with @Id:

public class MyEntity extends GenericModel {

   @Id
   public String code;

}
