Storing fields from a non entity parent

I have a class which I don't want it to be stored on the database, basically it is used for receiving such info from a http request.

class Address {
    private String address;
    private String postCode;

    // + getters and setters

}

Bear in mind that this class is not an entity. Now I'd like to create an entity by inheriting from it.

@Entity
class StorableAddress extends Address {
   // id and a few more fields.
}

When I save a StorableAddress it doesn't save any field from Address (address and postCode). Is there a solution for that or do I have to copy all the fields?

Short answer - you should copy values and not use inheritance.

What you are describing is a DTO pattern.

In order to avoid boilerplate code when working with DTOs, you can use tools like MapStruct
