Hibernate JPA @AssociationOverrides Example
The @AssociationOverrides is used to group several @AssociationOverride annotations.
@Target(value={TYPE,METHOD,FIELD})
@Retention(value=RUNTIME)
public @interface AssociationOverrides
Used to override mappings of multiple relationship properties or fields.
Example:
@MappedSuperclass
public class Employee {
@Id protected Integer id;
@Version protected Integer version;
@ManyToOne protected Address address;
@OneToOne protected Locker locker;
public Integer getId() { ... }
public void setId(Integer id) { ... }
public Address getAddress() { ... }
public void setAddress(Address address) { ... }
public Locker getLocker() { ... }
public void setLocker(Locker locker) { ... }
...
}
@Entity
@AssociationOverrides({
@AssociationOverride(
name="address",
joinColumns=@JoinColumn("ADDR_ID")),
@AttributeOverride(
name="locker",
joinColumns=@JoinColumn("LCKR_ID"))
})
public PartTimeEmployee { ... }
