方法详细资料

• 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 5.1/5.2, 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 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 5.2'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 PersistenceProvider getPersistenceProvider()

  从接口复制的说明: JpaVendorAdapter
  Return the vendor-specific persistence provider.

• getPersistenceProviderRootPackage

  public String getPersistenceProviderRootPackage()

  从接口复制的说明: 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.

  指定者:

  getPersistenceProviderRootPackage 在接口中 JpaVendorAdapter

  覆盖:

  getPersistenceProviderRootPackage 在类中 AbstractJpaVendorAdapter

• getJpaPropertyMap

  public Map<String,​Object> getJpaPropertyMap​(PersistenceUnitInfo pui)

  从接口复制的说明: 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 Java 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.

  指定者:

  getJpaPropertyMap 在接口中 JpaVendorAdapter

  覆盖:

  getJpaPropertyMap 在类中 AbstractJpaVendorAdapter

  参数:

  pui - the PersistenceUnitInfo for the current persistence unit

  返回:

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

  PersistenceUnitInfo.getTransactionType(), PersistenceProvider.createContainerEntityManagerFactory(PersistenceUnitInfo, Map)

• getJpaPropertyMap

  public Map<String,​Object> 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.

  指定者:

  getJpaPropertyMap 在接口中 JpaVendorAdapter

  覆盖:

  getJpaPropertyMap 在类中 AbstractJpaVendorAdapter

  返回:

  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

  protected Class<?> determineDatabaseDialectClass​(Database database)

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

  参数:

  database - the target database

  返回:

  the Hibernate database dialect class, or null if none found

• getJpaDialect

  public HibernateJpaDialect getJpaDialect()

  从接口复制的说明: JpaVendorAdapter
  Return the vendor-specific JpaDialect implementation for this provider, or null if there is none.

  指定者:

  getJpaDialect 在接口中 JpaVendorAdapter

  覆盖:

  getJpaDialect 在类中 AbstractJpaVendorAdapter

• getEntityManagerFactoryInterface

  public Class<? extends EntityManagerFactory> getEntityManagerFactoryInterface()

  从接口复制的说明: 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.

  指定者:

  getEntityManagerFactoryInterface 在接口中 JpaVendorAdapter

  覆盖:

  getEntityManagerFactoryInterface 在类中 AbstractJpaVendorAdapter

• getEntityManagerInterface

  public Class<? extends EntityManager> getEntityManagerInterface()

  从接口复制的说明: 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.

  指定者:

  getEntityManagerInterface 在接口中 JpaVendorAdapter

  覆盖:

  getEntityManagerInterface 在类中 AbstractJpaVendorAdapter
