Constructor Detail

HibernateTransactionManager

public HibernateTransactionManager()

Create a new HibernateTransactionManager instance. A SessionFactory has to be set to be able to use it.

See Also:

setSessionFactory(org.hibernate.SessionFactory)

HibernateTransactionManager

public HibernateTransactionManager(org.hibernate.SessionFactory sessionFactory)

Create a new HibernateTransactionManager instance.

Parameters:

sessionFactory - SessionFactory to manage transactions for

Method Detail

setSessionFactory

public void setSessionFactory(org.hibernate.SessionFactory sessionFactory)

Set the SessionFactory that this instance should manage transactions for.

getSessionFactory

public org.hibernate.SessionFactory getSessionFactory()

Return the SessionFactory that this instance should manage transactions for.

getDataSource

protected DataSource getDataSource()

Return the JDBC DataSource that this instance manages transactions for.

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.

Default is "true". If you turn this flag off, the transaction manager will not support per-transaction isolation levels anymore. It will not call Connection.setReadOnly(true) for read-only transactions anymore either. If this flag is turned off, no cleanup of a JDBC Connection is required after a transaction, since no Connection settings will get modified.

See Also:

Connection.setTransactionIsolation(int), Connection.setReadOnly(boolean)

setHibernateManagedSession

public void setHibernateManagedSession(boolean hibernateManagedSession)

Set whether to operate on a Hibernate-managed Session instead of a Spring-managed Session, that is, whether to obtain the Session through Hibernate's SessionFactory.getCurrentSession() instead of SessionFactory.openSession() (with a Spring TransactionSynchronizationManager check preceding it).

Default is "false", i.e. using a Spring-managed Session: taking the current thread-bound Session if available (e.g. in an Open-Session-in-View scenario), creating a new Session for the current transaction otherwise.

Switch this flag to "true" in order to enforce use of a Hibernate-managed Session. Note that this requires SessionFactory.getCurrentSession() to always return a proper Session when called for a Spring-managed transaction; transaction begin will fail if the getCurrentSession() call fails.

This mode will typically be used in combination with a custom Hibernate org.hibernate.context.CurrentSessionContext implementation that stores Sessions in a place other than Spring's TransactionSynchronizationManager. It may also be used in combination with Spring's Open-Session-in-View support (using Spring's default BeangleSessionContext), in which case it subtly differs from the Spring-managed Session mode: The pre-bound Session will not receive a clear() call (on rollback) or a disconnect() call (on transaction completion) in such a scenario; this is rather left up to a custom CurrentSessionContext implementation (if desired).

isSameConnectionForEntireSession

protected boolean isSameConnectionForEntireSession(org.hibernate.Session session)

Return whether the given Hibernate Session will always hold the same JDBC Connection. This is used to check whether the transaction manager can safely prepare and clean up the JDBC Connection used for a transaction.

Default implementation checks the Session's connection release mode to be "on_close". Unfortunately, this requires casting to SessionImpl, as of Hibernate 3.1. If that cast doesn't work, we'll simply assume we're safe and return true.

Parameters:

session - the Hibernate Session to check

See Also:

org.hibernate.impl.SessionImpl#getConnectionReleaseMode(), ConnectionReleaseMode.ON_CLOSE

convertHibernateAccessException

protected org.springframework.dao.DataAccessException convertHibernateAccessException(org.hibernate.HibernateException ex)

Convert the given HibernateException to an appropriate exception from the org.springframework.dao hierarchy.

Will automatically apply a specified SQLExceptionTranslator to a Hibernate JDBCException, else rely on Hibernate's default translation.

Parameters:

ex - HibernateException that occured

Returns:

a corresponding DataAccessException
