Interface JpaVendorAdapter

Method Detail

• getPersistenceProvider

  PersistenceProvider getPersistenceProvider()

  Return the vendor-specific persistence provider.

• getPersistenceProviderRootPackage

  String getPersistenceProviderRootPackage()

  Return the name of the persistence provider's root package (e.g. "oracle.toplink.essentials"). Will be used for excluding provider classes from temporary class overriding.

  Since:

  2.5.2

• getJpaPropertyMap

  Map<String,​?> getJpaPropertyMap​(PersistenceUnitInfo pui)

  Return a Map of vendor-specific JPA properties for the given persistence unit, typically based on settings in this JpaVendorAdapter instance.

  Note that there might be further JPA properties defined on the EntityManagerFactory bean, which might potentially override individual JPA property values specified here.

  This implementation delegates to getJpaPropertyMap() for non-unit-dependent properties. Effectively, this PersistenceUnitInfo-based variant only needs to be implemented if there is an actual need to react to unit-specific characteristics such as the transaction type.

  NOTE: This variant will only be invoked in case of Java EE style container bootstrapping where a PersistenceUnitInfo is present (i.e. LocalContainerEntityManagerFactoryBean. In case of simple Java SE style bootstrapping via Persistence (i.e. LocalEntityManagerFactoryBean), the parameter-less getJpaPropertyMap() variant will be called directly.

  Parameters:

  pui - the PersistenceUnitInfo for the current persistence unit

  Returns:

  a Map of JPA properties, as accepted by the standard JPA bootstrap facilities, or an empty Map if there are no properties to expose

  Since:

  4.3.13

  PersistenceUnitInfo.getTransactionType(), PersistenceProvider.createContainerEntityManagerFactory(PersistenceUnitInfo, Map)

• getJpaPropertyMap

  Map<String,​?> getJpaPropertyMap()

  Return a Map of vendor-specific JPA properties, typically based on settings in this JpaVendorAdapter instance.

  Note that there might be further JPA properties defined on the EntityManagerFactory bean, which might potentially override individual JPA property values specified here.

  Returns:

  a Map of JPA properties, as accepted by the standard JPA bootstrap facilities, or an empty Map if there are no properties to expose

  See Also:

  Persistence.createEntityManagerFactory(String, Map)

• getJpaDialect

  JpaDialect getJpaDialect()

  Return the vendor-specific JpaDialect implementation for this provider, or null if there is none.

• getEntityManagerFactoryInterface

  Class<? extends EntityManagerFactory> getEntityManagerFactoryInterface()

  Return the vendor-specific EntityManagerFactory interface that the EntityManagerFactory proxy is supposed to implement.

  If the provider does not offer any EntityManagerFactory extensions, the adapter should simply return the standard EntityManagerFactory class here.

  Since:

  2.5.2

• getEntityManagerInterface

  Class<? extends EntityManager> getEntityManagerInterface()

  Return the vendor-specific EntityManager interface that this provider's EntityManagers will implement.

  If the provider does not offer any EntityManager extensions, the adapter should simply return the standard EntityManager class here.

• postProcessEntityManagerFactory

  void postProcessEntityManagerFactory​(EntityManagerFactory emf)

  Optional callback for post-processing the native EntityManagerFactory before active use.

  This can be used for triggering vendor-specific initialization processes. While this is not expected to be used for most providers, it is included here as a general extension hook.
