Interface JpaVendorAdapter

All Known Implementing Classes:

AbstractJpaVendorAdapter, EclipseLinkJpaVendorAdapter, HibernateJpaVendorAdapter, OpenJpaVendorAdapter, TopLinkJpaVendorAdapter

public interface JpaVendorAdapter

SPI interface that allows to plug in vendor-specific behavior into Spring's EntityManagerFactory creators. Serves as single configuration point for all vendor-specific properties.

2.0

Method Summary

Class<? extends EntityManagerFactory>	getEntityManagerFactoryInterface() Return the vendor-specific EntityManagerFactory interface that the EntityManagerFactory proxy is supposed to implement.
Class<? extends EntityManager>	getEntityManagerInterface() Return the vendor-specific EntityManager interface that this provider's EntityManagers will implement.
JpaDialect	getJpaDialect() Return the vendor-specific JpaDialect implementation for this provider, or null if there is none.
Map<String,?>	getJpaPropertyMap() Return a Map of vendor-specific JPA properties, typically based on settings in this JpaVendorAdapter instance.
PersistenceProvider	getPersistenceProvider() Return the vendor-specific persistence provider.
String	getPersistenceProviderRootPackage() Return the name of the persistence provider's root package (e.g.
void	postProcessEntityManagerFactory(EntityManagerFactory emf) Optional callback for post-processing the native EntityManagerFactory before active use.

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()

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

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.
