hi,

I have an an Embeddable class Address which should be embedded into Customer.
Address contains the property type and this property I do not want to embed in the table CUSTOMER.

Is this possible and if so, how?

many thanks,
Stijn

Hi, have you tried using @Transient annotation on that field/getter?

Thanks for the suggestion.

I probably should have mentioned that Address is also used as 'stand-alone' entity and in this context 'type' is required.
I can hardly imagine it is not possible to only embed some properties of an embeddable entity.

thanks,
Stijn

All,

found a solution myself:

split up Address in 2 classes:

Code:

@Embeddable
@MappedSuperclass
public class EmbeddableAddress extends AbstractEntity {

    private String street;

    private String number;

    private String box;

and simply Address which contains the properties you do not want to be embeddable:

Code:

@Entity
@Table(name = "ADDRESS")
public class Address extends EmbeddableAddress {

    private AddressType addressType;

    private Long id;

tried it and works great.

regards,
Stijn
