All Implemented Interfaces:

JpaVendorAdapter

public class HibernateJpaVendorAdapter
extends AbstractJpaVendorAdapter

JpaVendorAdapter implementation for Hibernate EntityManager. Developed and tested against Hibernate 3.3.

Exposes Hibernate's persistence provider and EntityManager extension interface, and supports AbstractJpaVendorAdapter's common configuration settings.

Constructor Detail

HibernateJpaVendorAdapter

public HibernateJpaVendorAdapter()

Method Detail

getPersistenceProvider

public PersistenceProvider getPersistenceProvider()

Description copied from interface: JpaVendorAdapter

Return the vendor-specific persistence provider.

getPersistenceProviderRootPackage

public java.lang.String getPersistenceProviderRootPackage()

Description copied from interface: JpaVendorAdapter

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.

Specified by:

getPersistenceProviderRootPackage in interface JpaVendorAdapter

Overrides:

getPersistenceProviderRootPackage in class AbstractJpaVendorAdapter

getJpaPropertyMap

public java.util.Map<java.lang.String,java.lang.Object> getJpaPropertyMap()

Description copied from interface: JpaVendorAdapter

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.

Specified by:

getJpaPropertyMap in interface JpaVendorAdapter

Overrides:

getJpaPropertyMap in class AbstractJpaVendorAdapter

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

javax.persistence.Persistence#createEntityManagerFactory(String, java.util.Map), javax.persistence.spi.PersistenceProvider#createContainerEntityManagerFactory(javax.persistence.spi.PersistenceUnitInfo, java.util.Map)

determineDatabaseDialectClass

protected java.lang.Class determineDatabaseDialectClass(Database database)

Determine the Hibernate database dialect class for the given target database.

Parameters:

database - the target database

Returns:

the Hibernate database dialect class, or null if none found

getJpaDialect

public JpaDialect getJpaDialect()

Description copied from interface: JpaVendorAdapter

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

Specified by:

getJpaDialect in interface JpaVendorAdapter

Overrides:

getJpaDialect in class AbstractJpaVendorAdapter

getEntityManagerFactoryInterface

public java.lang.Class<? extends EntityManagerFactory> getEntityManagerFactoryInterface()

Description copied from interface: JpaVendorAdapter

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 javax.persistence.EntityManagerFactory class here.

Specified by:

getEntityManagerFactoryInterface in interface JpaVendorAdapter

Overrides:

getEntityManagerFactoryInterface in class AbstractJpaVendorAdapter

getEntityManagerInterface

public java.lang.Class<? extends EntityManager> getEntityManagerInterface()

Description copied from interface: JpaVendorAdapter

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 javax.persistence.EntityManager class here.

Specified by:

getEntityManagerInterface in interface JpaVendorAdapter

Overrides:

getEntityManagerInterface in class AbstractJpaVendorAdapter
