The EmbeddableId annotation is used to create a composite primary key. It can also be applied to a persistent field or property of an entity class or mapped superclass to denote a composite primary key that is an embeddable class.
Example:
@Embeddable public class Zipcode { protected String zip; protected String plusFour; } @Embeddable public class Address { protected String street; protected String city; protected String state; @EmbeddedId protected Zipcode zipcode; } |
