Interface Summary

Interface	Description
EntityManagerFactoryInfo	Metadata interface for a Spring-managed JPA EntityManagerFactory.
EntityManagerProxy	Subinterface of javax.persistence.EntityManager to be implemented by EntityManager proxies.
JpaDialect	SPI strategy that encapsulates certain functionality that standard JPA 2.1 does not offer, such as access to the underlying JDBC Connection.
JpaVendorAdapter	SPI interface that allows to plug in vendor-specific behavior into Spring's EntityManagerFactory creators.

Class Summary

Class	Description
AbstractEntityManagerFactoryBean	Abstract FactoryBean that creates a local JPA javax.persistence.EntityManagerFactory instance within a Spring application context.
AbstractEntityManagerFactoryBean.ManagedEntityManagerFactoryInvocationHandler	Dynamic proxy invocation handler proxying an EntityManagerFactory to return a proxy EntityManager if necessary from createEntityManager() methods.
AbstractEntityManagerFactoryBean.SerializedEntityManagerFactoryBeanReference	Minimal bean reference to the surrounding AbstractEntityManagerFactoryBean.
DefaultJpaDialect	Default implementation of the JpaDialect interface.
EntityManagerFactoryAccessor	Base class for any class that needs to access a JPA EntityManagerFactory, usually in order to obtain a JPA EntityManager.
EntityManagerFactoryUtils	Helper class featuring methods for JPA EntityManager handling, allowing for reuse of EntityManager instances within transactions.
EntityManagerFactoryUtils.TransactionalEntityManagerSynchronization	Callback for resource cleanup at the end of a non-JPA transaction (e.g.
EntityManagerFactoryUtils.TransactionScopedEntityManagerSynchronization	Minimal callback that just closes the EntityManager at the end of the transaction.
EntityManagerHolder	Holder wrapping a JPA EntityManager.
ExtendedEntityManagerCreator	Delegate for creating a variety of javax.persistence.EntityManager proxies that follow the JPA spec's semantics for "extended" EntityManagers.
ExtendedEntityManagerCreator.ExtendedEntityManagerInvocationHandler	InvocationHandler for extended EntityManagers as defined in the JPA spec.
ExtendedEntityManagerCreator.ExtendedEntityManagerSynchronization	TransactionSynchronization enlisting an extended EntityManager with a current Spring transaction.
JpaTransactionManager	PlatformTransactionManager implementation for a single JPA javax.persistence.EntityManagerFactory.
JpaTransactionManager.SuspendedResourcesHolder	Holder for suspended resources.
LocalContainerEntityManagerFactoryBean	FactoryBean that creates a JPA javax.persistence.EntityManagerFactory according to JPA's standard container bootstrap contract.
LocalEntityManagerFactoryBean	FactoryBean that creates a JPA javax.persistence.EntityManagerFactory according to JPA's standard standalone bootstrap contract.
SharedEntityManagerCreator	Delegate for creating a shareable JPA javax.persistence.EntityManager reference for a given javax.persistence.EntityManagerFactory.
SharedEntityManagerCreator.DeferredQueryInvocationHandler	Invocation handler that handles deferred Query objects created by non-transactional createQuery invocations on a shared EntityManager.
SharedEntityManagerCreator.SharedEntityManagerInvocationHandler	Invocation handler that delegates all calls to the current transactional EntityManager, if any; else, it will fall back to a newly created EntityManager per operation.

Exception Summary

Exception	Description
JpaObjectRetrievalFailureException	JPA-specific subclass of ObjectRetrievalFailureException.
JpaOptimisticLockingFailureException	JPA-specific subclass of ObjectOptimisticLockingFailureException.
JpaSystemException	JPA-specific subclass of UncategorizedDataAccessException, for JPA system errors that do not match any concrete org.springframework.dao exceptions.

Package org.springframework.orm.jpa Description

Package providing integration of JPA (Java Persistence API) with Spring concepts. Contains EntityManagerFactory helper classes, a template plus callback for JPA access, and an implementation of Spring's transaction SPI for local JPA transactions.
