Annotation Interface NaturalIdClass

@Target(TYPE)
@Retention(RUNTIME)
public @interface NaturalIdClass

Models a non-aggregated composite natural-id for the purpose of loading. The non-aggregated form uses multiple @NaturalId as opposed to the aggregated form which uses a single @NaturalId combined with @Embedded. Functions in a similar fashion as @IdClass for non-aggregated composite identifiers.

@Entity
@NaturalIdClass(OrderNaturalId.class)
class Order {
    @Id
	Integer id;
	@NaturalId @ManyToOne
	Customer customer;
	@NaturalId
	Integer orderNumber;
    ...
}

class OrderNaturalId {
	Customer customer;
	Integer orderNumber;
	...
}
