Annotation Type Embedded

@Target(FIELD)
@Retention(RUNTIME)
public @interface Embedded

Specifies a persistent field or property of an entity whose value is an instance of an embeddable class. The embeddable class must be annotated as Embeddable.

The AttributeOverride, AttributeOverrides, AssociationOverride, and AssociationOverrides annotations may be used to override mappings declared or defaulted by the embeddable class.

   Example:

   @Embedded
   @AttributeOverrides({
       @AttributeOverride(name="startDate", column=@Column("EMP_START")),
       @AttributeOverride(name="endDate", column=@Column("EMP_END"))
   })
   public EmploymentPeriod getEmploymentPeriod() { ... }
 

Since:
