Annotation Types Summary

Annotation Type	Description

DiscriminatorValue	Is used to specify the value of the discriminator column for entities of the given type.
Embeddable	Defines a class whose instances are stored as an intrinsic part of an owning entity and share the identity of the entity.
Embedded	Defines a persistent field or property of an entity whose value is an instance of an embeddable class.
EmbeddedId	Is 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.

ExcludeSuperclassListeners	Specifies that the invocation of superclass listeners is to be excluded for the entity class (or mapped superclass) and its subclasses.
FieldResult	Is used to map the columns specified in the SELECT list of the query to the properties or fields of the entity class.
GeneratedValue	Provides for the specification of generation strategies for the values of primary keys.
Id	Specifies the primary key property or field of an entity.
IdClass	Specifies a composite primary key class that is mapped to multiple fields or properties of the entity.
Inheritance	Defines the inheritance strategy to be used for an entity class hierarchy.
JoinColumn	Is used to specify a mapped column for joining an entity association.
JoinColumns	Defines mapping for the composite foreign keys.
JoinTable	This annotation is used in the mapping of associations.
Lob	Specifies that a persistent property or field should be persisted as a large object to a database-supported large object type.
ManyToMany	Defines a many-valued association with many-to-many multiplicity.
ManyToOne	This annotation defines a single-valued association to another entity class that has many-to-one multiplicity.
MapKey	Is used to specify the map key for associations of type Map.
MappedSuperclass	Designates a class whose mapping information is applied to the entities that inherit from it.
NamedNativeQueries	Is used to specify an array of native SQL named queries.
NamedNativeQuery	Is used to specify a native SQL named query.
NamedQueries	Specifies an array of named Java Persistence query language queries.
NamedQuery	Is used to specify a named query in the Java Persistence query language, which is a static query expressed in metadata.
OneToMany	Defines a many-valued association with one-to-many multiplicity.
OneToOne	This annotation defines a single-valued association to another entity that has one-to-one multiplicity.
OrderBy	This annotation specifies the ordering of the elements of a collection valued association at the point when the association is retrieved.
PersistenceContext	Expresses a dependency on an EntityManager persistence context.
PersistenceContexts	Declares one or more PersistenceContext annotations.
PersistenceProperty	Describes a single container or persistence provider property.
PersistenceUnit	Expresses a dependency on an EntityManagerFactory.
PersistenceUnits	Declares one or more PersistenceUnit annotations.
