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. Compatible with Hibernate ORM 7.x.

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()), for example, containing Hibernate FilterDef annotations, along with Spring-driven entity scanning which requires no persistence.xml (LocalContainerEntityManagerFactoryBean.setPackagesToScan(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(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 to HibernateJpaDialect.

      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 mode DELAYED_ACQUISITION_AND_HOLD in that case unless a user-specified connection handling mode property indicates otherwise; switch this flag to false to avoid that interference.

      NOTE: For a persistence unit with transaction type JTA, for example, 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

      public jakarta.persistence.spi.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 (for example, "oracle.toplink.essentials"). Will be used for excluding provider classes from temporary class overriding.
      Specified by:
      getPersistenceProviderRootPackage in interface JpaVendorAdapter

    • getJpaPropertyMap

      public Map<String,Object> getJpaPropertyMap(jakarta.persistence.spi.PersistenceUnitInfo pui)
      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 via Persistence (i.e. LocalEntityManagerFactoryBean), the parameter-less JpaVendorAdapter.getJpaPropertyMap() variant will be called directly.

      Specified by:
      getJpaPropertyMap in interface JpaVendorAdapter
      Overrides:
      getJpaPropertyMap in class AbstractJpaVendorAdapter
      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

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

    • determineDatabaseDialectClass

      protected @Nullable Class<?> determineDatabaseDialectClass(Database database)
      Determine the Hibernate database dialect class for the given target database.

      The default implementation covers the common built-in dialects.

      Parameters:
      database - the target database
      Returns:
      the Hibernate database dialect class, or null if none found
      See Also:

    • determineDatabaseDialectName

      protected @Nullable String determineDatabaseDialectName(Database database)
      Determine the Hibernate database dialect class name for the given target database.

      The default implementation covers the common community dialect for Derby.

      Parameters:
      database - the target database
      Returns:
      the Hibernate database dialect class name, or null if none found
