PersistenceUnit / For use with @EntityManager ; marks a field or T, M, and F

PersistenceUnits

property as representing the EntityManagerFactory
to be injected by the container.

PostLoad

load operation on the entity.

PostPersist

M Marks a method for invocation after performing a

persist operation on the entity.

PostRemove

M Marks a method for invocation after performing a

PostUpdate

update operation on the entity.

PrePersist

M Marks a method for invocation prior to performing

a persist operation on the entity.

PreRemove

M Marks a method for invocation prior to performing

a remove operation on the entity.

PreUpdate

PrimaryKeyJoinColumn /

T, M, and F Allows the columns joining a secondary table to a

PrimaryKeyJoinColumns primary table to be specified.

QueryHint

Pm Allows implementation-specific “hints” to be pro-

vided as a parameter of named queries and named
native queries.

SecondaryTable / T Allows an entity's basic fields and properties to be

SecondaryTables

persisted to more than one table.

SequenceGenerator

Pk, T, M, and F Allows a named primary key generator to be

defined for use by one or more entities.

SqlResultSetMapping Pk and T Allows an entity to be mapped as if it were a named

native query (i.e., so that it can be retrieved as a
conventional JDBC ResultSet ).

Table

T Pk, T, M, and F Allows the default details of an entity's primary

table to be overridden.

strategy of the generated value annotation is used
on the primary key field or property (the field or
property marked with the @Id annotation).

Temporal Specifies the behavior of Date and Calendar fields or

properties (if omitted, such fields will be treated as
TIMESTAMP values).

M and F

Transient

M and F Allows a field or property to be marked so that it

will not be persisted.

UniqueConstraint

Pm Enforces a unique constraint at schema generation

time as a parameter of @Table .

Version

M and F Marks the field or property serving as the optimistic
