Interface EntityManagerFactoryInfo

All Known Implementing Classes:
AbstractEntityManagerFactoryBean, LocalContainerEntityManagerFactoryBean, LocalEntityManagerFactoryBean
public interface EntityManagerFactoryInfo
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.

  • Method Details

    • getPersistenceProvider

      @Nullable 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

    • getPersistenceUnitInfo

      @Nullable 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

    • getPersistenceUnitName

      @Nullable 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().

    • getDataSource

      @Nullable DataSource getDataSource()
      Return the JDBC DataSource that this EntityManagerFactory obtains its JDBC Connections from.
      Returns:
      the JDBC DataSource, or null if not known

    • getEntityManagerInterface

      @Nullable 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 jakarta.persistence.EntityManager.

    • getJpaDialect

      @Nullable JpaDialect getJpaDialect()
      Return the vendor-specific JpaDialect implementation for this EntityManagerFactory, or null if not known.

    • getBeanClassLoader

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

      Proxies will be generated in this ClassLoader.

    • getNativeEntityManagerFactory

      EntityManagerFactory getNativeEntityManagerFactory()
      Return the raw underlying EntityManagerFactory.
      Returns:
      the unadorned EntityManagerFactory (never null)

    • createNativeEntityManager

      EntityManager createNativeEntityManager(@Nullable Map<?,?> properties)
      Create a native JPA EntityManager to be used as the framework-managed resource behind an application-level EntityManager handle.

      This exposes a native EntityManager from the underlying native EntityManagerFactory, taking JpaVendorAdapter.postProcessEntityManager(EntityManager) into account.
