Class HibernateJpaVendorAdapter
- All Implemented Interfaces:
JpaVendorAdapter
JpaVendorAdapter
implementation for Hibernate
EntityManager.
Exposes Hibernate's persistence provider and Hibernate's Session as extended
EntityManager 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...)
).
A note about HibernateJpaVendorAdapter
vs native Hibernate settings:
Some settings on this adapter may conflict with native Hibernate configuration rules
or custom Hibernate properties. For example, specify either AbstractJpaVendorAdapter.setDatabase(org.springframework.orm.jpa.vendor.Database)
or
Hibernate's "hibernate.dialect_resolvers" property, not both. Also, be careful about
Hibernate's connection release mode: This adapter prefers ON_CLOSE
behavior,
aligned with HibernateJpaDialect.setPrepareConnection(boolean)
, at least for non-JTA
scenarios; you may override this through corresponding native Hibernate properties.

setPrepareConnection
public void setPrepareConnection(boolean prepareConnection) Set whether to prepare the underlying JDBC Connection of a transactional Hibernate Session, that is, whether to apply a transaction-specific isolation level and/or the transaction's read-only flag to the underlying JDBC Connection.See
HibernateJpaDialect.setPrepareConnection(boolean)
for details. This is just a convenience flag passed through toHibernateJpaDialect
.On Hibernate 5.1+, this flag remains
true
by default like against previous Hibernate versions. The vendor adapter manually enforces Hibernate's new connection handling modeDELAYED_ACQUISITION_AND_HOLD
in that case unless a user-specified connection handling mode property indicates otherwise; switch this flag tofalse
to avoid that interference.NOTE: For a persistence unit with transaction type JTA e.g. on WebLogic, the connection release mode will never be altered from its provider default, i.e. not be forced to
DELAYED_ACQUISITION_AND_HOLD
by this flag. Alternatively, set Hibernate's "hibernate.connection.handling_mode" property to "DELAYED_ACQUISITION_AND_RELEASE_AFTER_TRANSACTION" or even "DELAYED_ACQUISITION_AND_RELEASE_AFTER_STATEMENT" in such a scenario. -
getPersistenceProvider
Description copied from interface:JpaVendorAdapter
Return the vendor-specific persistence provider. -
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 interfaceJpaVendorAdapter
- Overrides:
getPersistenceProviderRootPackage
in classAbstractJpaVendorAdapter
-
getJpaPropertyMap
Description copied from interface:JpaVendorAdapter
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
JpaVendorAdapter.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 Jakarta EE style container bootstrapping where a
PersistenceUnitInfo
is present (i.e.LocalContainerEntityManagerFactoryBean
). In case of simple Java SE style bootstrapping viaPersistence
(i.e.LocalEntityManagerFactoryBean
), the parameter-lessJpaVendorAdapter.getJpaPropertyMap()
variant will be called directly.- Specified by:
getJpaPropertyMap
in interfaceJpaVendorAdapter
- Overrides:
getJpaPropertyMap
in classAbstractJpaVendorAdapter
- 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

determineDatabaseDialectClass
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

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
