JPA Inheritance - @MappedSuperclass
Description: This application is a sample of using the JPA @MappedSuperclass.
Key points:
- the base class is not an entity, it can be
abstract, and is annotated with@MappedSuperclass - subclasses of the base class are mapped in tables that contains columns for the inherited attributes and for their own attibutes
- when the base class doens't need to be an entity, the
@MappedSuperclassis the proper alternative to the JPA table-per-class inheritance strategy
