• FLUSH_NEVER

  public static final int FLUSH_NEVER

  已过时。
  Never flush is a good strategy for read-only units of work. Hibernate will not track and look for changes in this case, avoiding any overhead of modification detection.

  In case of an existing Session, FLUSH_NEVER will turn the flush mode to NEVER for the scope of the current operation, resetting the previous flush mode afterwards.

• FLUSH_AUTO

  public static final int FLUSH_AUTO

  已过时。
  Automatic flushing is the default mode for a Hibernate Session. A session will get flushed on transaction commit, and on certain find operations that might involve already modified instances, but not after each unit of work like with eager flushing.

  In case of an existing Session, FLUSH_AUTO will participate in the existing flush mode, not modifying it for the current operation. This in particular means that this setting will not modify an existing flush mode NEVER, in contrast to FLUSH_EAGER.

• FLUSH_EAGER

  public static final int FLUSH_EAGER

  已过时。
  Eager flushing leads to immediate synchronization with the database, even if in a transaction. This causes inconsistencies to show up and throw a respective exception immediately, and JDBC access code that participates in the same transaction will see the changes as the database is already aware of them then. But the drawbacks are:

  • additional communication roundtrips with the database, instead of a single batch at transaction commit;
  • the fact that an actual database rollback is needed if the Hibernate transaction rolls back (due to already submitted SQL statements).

  In case of an existing Session, FLUSH_EAGER will turn the flush mode to AUTO for the scope of the current operation and issue a flush at the end, resetting the previous flush mode afterwards.

• FLUSH_COMMIT

  public static final int FLUSH_COMMIT

  已过时。
  Flushing at commit only is intended for units of work where no intermediate flushing is desired, not even for find operations that might involve already modified instances.

  In case of an existing Session, FLUSH_COMMIT will turn the flush mode to COMMIT for the scope of the current operation, resetting the previous flush mode afterwards. The only exception is an existing flush mode NEVER, which will not be modified through this setting.

• FLUSH_ALWAYS

  public static final int FLUSH_ALWAYS

  已过时。
  Flushing before every query statement is rarely necessary. It is only available for special needs.

  In case of an existing Session, FLUSH_ALWAYS will turn the flush mode to ALWAYS for the scope of the current operation, resetting the previous flush mode afterwards.

方法详细资料

• setSessionFactory

  public void setSessionFactory​(SessionFactory sessionFactory)

  已过时。
  Set the Hibernate SessionFactory that should be used to create Hibernate Sessions.

• getSessionFactory

  public SessionFactory getSessionFactory()

  已过时。
  Return the Hibernate SessionFactory that should be used to create Hibernate Sessions.

• setEntityInterceptorBeanName

  public void setEntityInterceptorBeanName​(String entityInterceptorBeanName)

  已过时。
  Set the bean name of a Hibernate entity interceptor that allows to inspect and change property values before writing to and reading from the database. Will get applied to any new Session created by this transaction manager.

  Requires the bean factory to be known, to be able to resolve the bean name to an interceptor instance on session creation. Typically used for prototype interceptors, i.e. a new interceptor instance per session.

  Can also be used for shared interceptor instances, but it is recommended to set the interceptor reference directly in such a scenario.

  参数:

  entityInterceptorBeanName - the name of the entity interceptor in the bean factory

  另请参阅:

  setBeanFactory(org.springframework.beans.factory.BeanFactory), setEntityInterceptor(org.hibernate.Interceptor)

• setEntityInterceptor

  public void setEntityInterceptor​(Interceptor entityInterceptor)

  已过时。
  Set a Hibernate entity interceptor that allows to inspect and change property values before writing to and reading from the database. Will get applied to any new Session created by this object.

  Such an interceptor can either be set at the SessionFactory level, i.e. on LocalSessionFactoryBean, or at the Session level, i.e. on HibernateTemplate, HibernateInterceptor, and HibernateTransactionManager. It's preferable to set it on LocalSessionFactoryBean or HibernateTransactionManager to avoid repeated configuration and guarantee consistent behavior in transactions.

                                          BeansException

  已过时。
  Return the current Hibernate entity interceptor, or null if none. Resolves an entity interceptor bean name via the bean factory, if necessary.

  抛出:

  IllegalStateException - if bean name specified but no bean factory set

  BeansException - if bean name resolution via the bean factory failed
