24 | javax.persistence.UniqueConstraintjavax.persistence Annotation UniqueConstraint Target: Specifies that a unique constraint is to be included in the generated DDL for a primary or secondary table. Example: @Entity @Table( name="EMPLOYEE", uniqueConstraints= @UniqueConstraint(columnNames={"EMP_ID |
24 | javax.persistence.PrimaryKeyJoinColumnsjavax.persistence Annotation PrimaryKeyJoinColumns Target: Classes and fields (including property get methods) Groups PrimaryKeyJoinColumn annotations. It is used to map composite foreign keys. Example: ValuedCustomer subclass @Entity @Table(name="VCUST") @DiscriminatorValue("VCUST |
24 | javax.persistence.PrePersistjavax.persistence Annotation PrePersist Target: Callback methods Is used to specify callback methods for the corresponding lifecycle event. This annotation may be applied to methods of an entity class, a mapped superclass, or a callback listener class. Since: JPA 1.0 Learn how to define and use JPA |
24 | javax.persistence.PrimaryKeyJoinColumnjavax.persistence Annotation PrimaryKeyJoinColumn Target: Classes and fields (including property get methods) Specifies a primary key column that is used as a foreign key to join to another table. It is used to join the primary table of an entity subclass in the JOINED mapping strategy |
