EntityManagerFactoryInfo

org.springframework.orm.jpa.EntityManagerFactoryInfo
Known Indirect Subclasses

Class Overview

Metadata interface for a Spring-managed JPA EntityManagerFactory.

This facility can be obtained from Spring-managed EntityManagerFactory proxies through casting the EntityManagerFactory handle to this interface.

Summary

Public Methods
abstract ClassLoader getBeanClassLoader()
Return the ClassLoader that the application's beans are loaded with.
abstract DataSource getDataSource()
Return the JDBC DataSource that this EntityManagerFactory obtains its JDBC Connections from.
abstract Class<? extends EntityManager> getEntityManagerInterface()
Return the (potentially vendor-specific) EntityManager interface that this factory's EntityManagers will implement.
abstract JpaDialect getJpaDialect()
Return the vendor-specific JpaDialect implementation for this EntityManagerFactory, or null if not known.
abstract EntityManagerFactory getNativeEntityManagerFactory()
Return the raw underlying EntityManagerFactory.
abstract PersistenceProvider getPersistenceProvider()
Return the underlying PersistenceProvider that the underlying EntityManagerFactory was created with.
abstract PersistenceUnitInfo getPersistenceUnitInfo()
Return the PersistenceUnitInfo used to create this EntityManagerFactory, if the in-container API was used.
abstract String getPersistenceUnitName()
Return the name of the persistence unit used to create this EntityManagerFactory, or null if it is an unnamed default.

Public Methods

public abstract ClassLoader getBeanClassLoader ()

Return the ClassLoader that the application's beans are loaded with.

Proxies will be generated in this ClassLoader.

public abstract DataSource getDataSource ()

Return the JDBC DataSource that this EntityManagerFactory obtains its JDBC Connections from.

Returns
  • the JDBC DataSource, or null if not known

public abstract Class<? extends EntityManager> getEntityManagerInterface ()

Return the (potentially vendor-specific) EntityManager interface that this factory's EntityManagers will implement.

A null return value suggests that autodetection is supposed to happen: either based on a target EntityManager instance or simply defaulting to javax.persistence.EntityManager.

public abstract JpaDialect getJpaDialect ()

Return the vendor-specific JpaDialect implementation for this EntityManagerFactory, or null if not known.

public abstract EntityManagerFactory getNativeEntityManagerFactory ()

Return the raw underlying EntityManagerFactory.

Returns
  • the unadorned EntityManagerFactory (never null)

public abstract PersistenceProvider getPersistenceProvider ()

Return the underlying PersistenceProvider that the underlying EntityManagerFactory was created with.

Returns
  • the PersistenceProvider used to create this EntityManagerFactory, or null if the standard JPA provider autodetection process was used to configure the EntityManagerFactory

public abstract PersistenceUnitInfo getPersistenceUnitInfo ()

Return the PersistenceUnitInfo used to create this EntityManagerFactory, if the in-container API was used.

Returns
  • the PersistenceUnitInfo used to create this EntityManagerFactory, or null if the in-container contract was not used to configure the EntityManagerFactory

public abstract String getPersistenceUnitName ()

Return the name of the persistence unit used to create this EntityManagerFactory, or null if it is an unnamed default.

If getPersistenceUnitInfo() returns non-null, the result of getPersistenceUnitName() must be equal to the value returned by PersistenceUnitInfo.getPersistenceUnitName().
