Class HibernateJpaVendorAdapter

java.lang.Object

org.springframework.orm.jpa.vendor.AbstractJpaVendorAdapter

org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter

All Implemented Interfaces:

JpaVendorAdapter

public class HibernateJpaVendorAdapter
extends AbstractJpaVendorAdapter

JpaVendorAdapter implementation for Hibernate EntityManager. Developed and tested against Hibernate 3.6, 4.2/4.3 as well as 5.0. Hibernate 4.2+ is strongly recommended for use with Spring 4.0+.

Exposes Hibernate's persistence provider and EntityManager extension interface, and adapts AbstractJpaVendorAdapter's common configuration settings. Also supports the detection of annotated packages (through SmartPersistenceUnitInfo.getManagedPackages()), e.g. containing Hibernate FilterDef annotations, along with Spring-driven entity scanning which requires no persistence.xml (LocalContainerEntityManagerFactoryBean.setPackagesToScan(java.lang.String...)).

Note that the package location of Hibernate's JPA support changed from 4.2 to 4.3: from org.hibernate.ejb.HibernateEntityManager(Factory) to org.hibernate.jpa.HibernateEntityManager(Factory). As of Spring 4.0, we're exposing the correct, non-deprecated variant depending on the Hibernate version encountered at runtime, in order to avoid deprecation log entries.

Since:

2.0

Constructor Detail

HibernateJpaVendorAdapter

public HibernateJpaVendorAdapter()

Method Detail

getPersistenceProvider

public PersistenceProvider getPersistenceProvider()

Description copied from interface: JpaVendorAdapter

Return the vendor-specific persistence provider.

getPersistenceProviderRootPackage

public 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 Map<String,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

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

determineDatabaseDialectClass

protected 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 HibernateJpaDialect 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 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 EntityManagerFactory class here.

Specified by:

getEntityManagerFactoryInterface in interface JpaVendorAdapter

Overrides:

getEntityManagerFactoryInterface in class AbstractJpaVendorAdapter

getEntityManagerInterface

public 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 EntityManager class here.

Specified by:

getEntityManagerInterface in interface JpaVendorAdapter

Overrides:

getEntityManagerInterface in class AbstractJpaVendorAdapter
