Сущности (Entities)
+
+
An entity is a lightweight persistent domain object. The primary programming artifact is the entity class. An
+ entity class may make use of auxiliary classes that serve as helper classes or that are used to represent the
+ state of the entity.
+
+
Entity Class
+
+
+
+ The entity class must be annotated with the Entity annotation or denoted in the XML descriptor as an
+ entity.
+
+
+ The entity class must have a no-arg constructor. The entity class may have other constructors as well.
+ The no-arg constructor must be public or protected.
+
+
+ The entity class must be a top-level class. An enum or interface must not be designated as an entity.
+
+
+ The entity class must not be final. No methods or persistent instance variables of the entity class may be
+ final.
+
+
+ If an entity instance is to be passed by value as a detached object (e.g., through a remote interface), the
+ entity class must implement the Serializable interface.
+
+
+ Entities support inheritance, polymorphic associations, and polymorphic queries.
+
+
+ Both abstract and concrete classes can be entities. Entities may extend non-entity classes as well as
+ entity classes, and non-entity classes may extend entity classes.
+
+
+ The persistent state of an entity is represented by instance variables, which may correspond to Java-
+ Beans properties. An instance variable must be directly accessed only from within the methods of the
+ entity by the entity instance itself. Instance variables must not be accessed by clients of the entity. The
+ state of the entity is available to clients only through the entity’s methods—i.e., accessor methods (getter/
+ setter methods) or other business methods.
+
+
+
+
Entity State in Persistence Context
+
+
+
+ transient
+ the entity has just been instantiated and is not associated with a persistence context.
+ It has no persistent representation in the database and typically no identifier value
+ has been assigned (unless the assigned generator was used).
+
+
+ managed, or persistent
+ the entity has an associated identifier and is associated with a persistence
+ context. It may or may not physically exist in the database yet.
+
+
+ detached
+ the entity has an associated identifier but is no longer associated with a persistence
+ context (usually because the persistence context was closed or the instance was evicted
+ from the context)
+
+
+ removed
+ the entity has an associated identifier and is associated with a persistence context,
+ however, it is scheduled for removal from the database.
+
+
+
+
Entity Lifecycle
+
+
+
+ Entity Instance Creation
+ Entity instances are created by means of the new operation. An entity instance, when first created by
+ new is not yet persistent. An instance becomes persistent by means of the EntityManager API.
+
+
+ Persisting an Entity Instance
+ A new entity instance becomes both managed and persistent by invoking the persist method on it or
+ by cascading the persist operation.
+ The semantics of the persist operation, applied to an entity X are as follows:
+
+
+ If X is a new entity, it becomes managed. The entity X will be entered into the database at or
+ before transaction commit or as a result of the flush operation.
+
+
+ If X is a preexisting managed entity, it is ignored by the persist operation. However, the persist
+ operation is cascaded to entities referenced by X, if the relationships from X to these other
+ entities are annotated with the cascade=PERSIST or cascade=ALL annotation element
+ value or specified with the equivalent XML descriptor element.
+
+
+ If X is a removed entity, it becomes managed.
+
+
+ If X is a detached object, the EntityExistsException may be thrown when the persist
+ operation is invoked, or the EntityExistsException or another PersistenceException
+ may be thrown at flush or commit time.
+
+
+ For all entities Y referenced by a relationship from X, if the relationship to Y has been annotated
+ with the cascade element value cascade=PERSIST or cascade=ALL, the persist
+ operation is applied to Y.
+
+
+
+
+ Removal
+ A managed entity instance becomes removed by invoking the remove method on it or by cascading the
+ remove operation.
+ The semantics of the remove operation, applied to an entity X are as follows:
+
+
+ If X is a new entity, it is ignored by the remove operation. However, the remove operation is
+ cascaded to entities referenced by X, if the relationship from X to these other entities is annotated
+ with the cascade=REMOVE or cascade=ALL annotation element value.
+
+
+ If X is a detached entity, an IllegalArgumentException will be thrown by the remove
+ operation (or the transaction commit will fail).
+
+
+ If X is a removed entity, it is ignored by the remove operation.
+
+
+ A removed entity X will be removed from the database at or before transaction commit or as a
+ result of the flush operation.
+
+
+ After an entity has been removed, its state (except for generated state) will be that of the entity at the
+ point at which the remove operation was called.
