public class HibernateTransactionManager extends AbstractPlatformTransactionManager implements ResourceTransactionManager, BeanFactoryAware, InitializingBean
PlatformTransactionManager
implementation for a single HibernateSessionFactory
. Binds a Hibernate Session from the specified factory to the thread, potentially allowing for one thread-bound Session per factory.SessionFactory.getCurrentSession()
is required for Hibernate access code that needs to support this transaction handling mechanism, with the SessionFactory being configured withSpringSessionContext
.Supports custom isolation levels, and timeouts that get applied as Hibernate transaction timeouts.
This transaction manager is appropriate for applications that use a single Hibernate SessionFactory for transactional data access, but it also supports direct DataSource access within a transaction (i.e. plain JDBC code working with the same DataSource). This allows for mixing services which access Hibernate and services which use plain JDBC (without being aware of Hibernate)! Application code needs to stick to the same simple Connection lookup pattern as with
DataSourceTransactionManager
(i.e.DataSourceUtils.getConnection(javax.sql.DataSource)
or going through aTransactionAwareDataSourceProxy
).Note: To be able to register a DataSource's Connection for plain JDBC code, this instance needs to be aware of the DataSource (
setDataSource(javax.sql.DataSource)
). The given DataSource should obviously match the one used by the given SessionFactory.JTA (usually through
JtaTransactionManager
) is necessary for accessing multiple transactional resources within the same transaction. The DataSource that Hibernate uses needs to be JTA-enabled in such a scenario (see container setup).This transaction manager supports nested transactions via JDBC 3.0 Savepoints. The
AbstractPlatformTransactionManager.setNestedTransactionAllowed(boolean)
"nestedTransactionAllowed"} flag defaults to "false", though, as nested transactions will just apply to the JDBC Connection, not to the Hibernate Session and its cached entity objects and related context. You can manually set the flag to "true" if you want to use nested transactions for JDBC access code which participates in Hibernate transactions (provided that your JDBC driver supports Savepoints). Note that Hibernate itself does not support nested transactions! Hence, do not expect Hibernate access code to semantically participate in a nested transaction.NOTE: Hibernate 4.2+ is strongly recommended for efficient transaction management with Spring, in particular for transactional Spring JDBC access.

Constructor Detail
HibernateTransactionManager
public HibernateTransactionManager()
Create a new HibernateTransactionManager instance. A SessionFactory has to be set to be able to use it.
HibernateTransactionManager
public HibernateTransactionManager(SessionFactory sessionFactory)
Create a new HibernateTransactionManager instance.- Parameters:
sessionFactory
- SessionFactory to manage transactions for
Method Detail
setSessionFactory
public void setSessionFactory(SessionFactory sessionFactory)
Set the SessionFactory that this instance should manage transactions for.
getSessionFactory
public SessionFactory getSessionFactory()
Return the SessionFactory that this instance should manage transactions for.
setDataSource
public void setDataSource(DataSource dataSource)
Set the JDBC DataSource that this instance should manage transactions for. The DataSource should match the one used by the Hibernate SessionFactory: for example, you could specify the same JNDI DataSource for both.If the SessionFactory was configured with LocalDataSourceConnectionProvider, i.e. by Spring's LocalSessionFactoryBean with a specified "dataSource", the DataSource will be auto-detected: You can still explicitly specify the DataSource, but you don't need to in this case.
A transactional JDBC Connection for this DataSource will be provided to application code accessing this DataSource directly via DataSourceUtils or JdbcTemplate. The Connection will be taken from the Hibernate Session.
The DataSource specified here should be the target DataSource to manage transactions for, not a TransactionAwareDataSourceProxy. Only data access code may work with TransactionAwareDataSourceProxy, while the transaction manager needs to work on the underlying target DataSource. If there's nevertheless a TransactionAwareDataSourceProxy passed in, it will be unwrapped to extract its target DataSource.
getDataSource
public DataSource getDataSource()
Return the JDBC DataSource that this instance manages transactions for.
setAutodetectDataSource
public void setAutodetectDataSource(boolean autodetectDataSource)
Set whether to autodetect a JDBC DataSource used by the Hibernate SessionFactory, if set via LocalSessionFactoryBean'ssetDataSource
. Default is "true".Can be turned off to deliberately ignore an available DataSource, in order to not expose Hibernate transactions as JDBC transactions for that DataSource.
- See Also:
setDataSource(javax.sql.DataSource)
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.
setAllowResultAccessAfterCompletion
public void setAllowResultAccessAfterCompletion(boolean allowResultAccessAfterCompletion)
Set whether to allow result access after completion, typically via Hibernate's ScrollableResults mechanism.Default is "false". Turning this flag on enforces over-commit holdability on the underlying JDBC Connection (if
"prepareConnection"
is on) and skips the disconnect-on-completion step.- Since:
- 4.1.2
- See Also:
Connection.setHoldability(int)
,ResultSet.HOLD_CURSORS_OVER_COMMIT
,disconnectOnCompletion(Session)
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'sSessionFactory.getCurrentSession()
instead ofSessionFactory.openSession()
(with a SpringTransactionSynchronizationManager
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 thegetCurrentSession()
call fails.This mode will typically be used in combination with a custom Hibernate
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 defaultSpringSessionContext
), in which case it subtly differs from the Spring-managed Session mode: The pre-bound Session will not receive aclear()
call (on rollback) or adisconnect()
call (on transaction completion) in such a scenario; this is rather left up to a custom CurrentSessionContext implementation (if desired).
setEntityInterceptorBeanName
public void setEntityInterceptorBeanName(String entityInterceptorBeanName)
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.
- Parameters:
entityInterceptorBeanName
- the name of the entity interceptor in the bean factory- See Also:
setBeanFactory(org.springframework.beans.factory.BeanFactory)
,setEntityInterceptor(org.hibernate.Interceptor)
setEntityInterceptor
public void setEntityInterceptor(Interceptor entityInterceptor)
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 transaction manager.Such an interceptor can either be set at the SessionFactory level, i.e. on LocalSessionFactoryBean, or at the Session level, i.e. on HibernateTransactionManager.
getEntityInterceptor
public Interceptor getEntityInterceptor() throws IllegalStateException, BeansException
Return the current Hibernate entity interceptor, ornull
if none. Resolves an entity interceptor bean name via the bean factory, if necessary.- Throws:
IllegalStateException
- if bean name specified but no bean factory setBeansException
- if bean name resolution via the bean factory failed- See Also:
setEntityInterceptor(org.hibernate.Interceptor)
,setEntityInterceptorBeanName(java.lang.String)
,setBeanFactory(org.springframework.beans.factory.BeanFactory)
setBeanFactory
public void setBeanFactory(BeanFactory beanFactory)
The bean factory just needs to be known for resolving entity interceptor bean names. It does not need to be set for any other mode of operation.- Specified by:
setBeanFactory
in interfaceBeanFactoryAware
- Parameters:
beanFactory
- owning BeanFactory (nevernull
). The bean can immediately call methods on the factory.- See Also:
setEntityInterceptorBeanName(java.lang.String)
afterPropertiesSet
public void afterPropertiesSet()
Description copied from interface:InitializingBean
Invoked by the containingBeanFactory
after it has set all bean properties and satisfiedBeanFactoryAware
,ApplicationContextAware
etc.This method allows the bean instance to perform validation of its overall configuration and final initialization when all bean properties have been set.
- Specified by:
afterPropertiesSet
in interfaceInitializingBean
getResourceFactory
public Object getResourceFactory()
Description copied from interface:ResourceTransactionManager
Return the resource factory that this transaction manager operates on, e.g. a JDBC DataSource or a JMS ConnectionFactory.This target resource factory is usually used as resource key for
TransactionSynchronizationManager
's resource bindings per thread.- Specified by:
getResourceFactory
in interfaceResourceTransactionManager
- Returns:
- the target resource factory (never
null
) - See Also:
TransactionSynchronizationManager.bindResource(java.lang.Object, java.lang.Object)
,TransactionSynchronizationManager.getResource(java.lang.Object)
doGetTransaction
protected Object doGetTransaction()
Description copied from class:AbstractPlatformTransactionManager
Return a transaction object for the current transaction state.The returned object will usually be specific to the concrete transaction manager implementation, carrying corresponding transaction state in a modifiable fashion. This object will be passed into the other template methods (e.g. doBegin and doCommit), either directly or as part of a DefaultTransactionStatus instance.
The returned object should contain information about any existing transaction, that is, a transaction that has already started before the current
getTransaction
call on the transaction manager. Consequently, adoGetTransaction
implementation will usually look for an existing transaction and store corresponding state in the returned transaction object.- Specified by:
doGetTransaction
in classAbstractPlatformTransactionManager
- Returns:
- the current transaction object
- See Also:
AbstractPlatformTransactionManager.doBegin(java.lang.Object, org.springframework.transaction.TransactionDefinition)
,AbstractPlatformTransactionManager.doCommit(org.springframework.transaction.support.DefaultTransactionStatus)
,AbstractPlatformTransactionManager.doRollback(org.springframework.transaction.support.DefaultTransactionStatus)
,DefaultTransactionStatus.getTransaction()
isExistingTransaction
protected boolean isExistingTransaction(Object transaction)
Description copied from class:AbstractPlatformTransactionManager
Check if the given transaction object indicates an existing transaction (that is, a transaction which has already started).The result will be evaluated according to the specified propagation behavior for the new transaction. An existing transaction might get suspended (in case of PROPAGATION_REQUIRES_NEW), or the new transaction might participate in the existing one (in case of PROPAGATION_REQUIRED).
The default implementation returns
false
, assuming that participating in existing transactions is generally not supported. Subclasses are of course encouraged to provide such support.- Overrides:
isExistingTransaction
in classAbstractPlatformTransactionManager
- Parameters:
transaction
- transaction object returned by doGetTransaction- Returns:
- if there is an existing transaction
- See Also:
AbstractPlatformTransactionManager.doGetTransaction()
doBegin
protected void doBegin(Object transaction, TransactionDefinition definition)
Description copied from class:AbstractPlatformTransactionManager
Begin a new transaction with semantics according to the given transaction definition. Does not have to care about applying the propagation behavior, as this has already been handled by this abstract manager.This method gets called when the transaction manager has decided to actually start a new transaction. Either there wasn't any transaction before, or the previous transaction has been suspended.
A special scenario is a nested transaction without savepoint: If
useSavepointForNestedTransaction()
returns "false", this method will be called to start a nested transaction when necessary. In such a context, there will be an active transaction: The implementation of this method has to detect this and start an appropriate nested transaction.- Specified by:
doBegin
in classAbstractPlatformTransactionManager
- Parameters:
transaction
- transaction object returned bydoGetTransaction
definition
- TransactionDefinition instance, describing propagation behavior, isolation level, read-only flag, timeout, and transaction name
doSuspend
protected Object doSuspend(Object transaction)
Description copied from class:AbstractPlatformTransactionManager
Suspend the resources of the current transaction. Transaction synchronization will already have been suspended.The default implementation throws a TransactionSuspensionNotSupportedException, assuming that transaction suspension is generally not supported.
- Overrides:
doSuspend
in classAbstractPlatformTransactionManager
- Parameters:
transaction
- transaction object returned bydoGetTransaction
- Returns:
- an object that holds suspended resources (will be kept unexamined for passing it into doResume)
- See Also:
AbstractPlatformTransactionManager.doResume(java.lang.Object, java.lang.Object)
doResume
protected void doResume(Object transaction, Object suspendedResources)
Description copied from class:AbstractPlatformTransactionManager
Resume the resources of the current transaction. Transaction synchronization will be resumed afterwards.The default implementation throws a TransactionSuspensionNotSupportedException, assuming that transaction suspension is generally not supported.
- Overrides:
doResume
in classAbstractPlatformTransactionManager
- Parameters:
transaction
- transaction object returned bydoGetTransaction
suspendedResources
- the object that holds suspended resources, as returned by doSuspend- See Also:
AbstractPlatformTransactionManager.doSuspend(java.lang.Object)
doCommit
protected void doCommit(DefaultTransactionStatus status)
Description copied from class:AbstractPlatformTransactionManager
Perform an actual commit of the given transaction.An implementation does not need to check the "new transaction" flag or the rollback-only flag; this will already have been handled before. Usually, a straight commit will be performed on the transaction object contained in the passed-in status.
- Specified by:
doCommit
in classAbstractPlatformTransactionManager
- Parameters:
status
- the status representation of the transaction- See Also:
DefaultTransactionStatus.getTransaction()
doRollback
protected void doRollback(DefaultTransactionStatus status)
Description copied from class:AbstractPlatformTransactionManager
Perform an actual rollback of the given transaction.An implementation does not need to check the "new transaction" flag; this will already have been handled before. Usually, a straight rollback will be performed on the transaction object contained in the passed-in status.
- Specified by:
doRollback
in classAbstractPlatformTransactionManager
- Parameters:
status
- the status representation of the transaction- See Also:
DefaultTransactionStatus.getTransaction()
doSetRollbackOnly
protected void doSetRollbackOnly(DefaultTransactionStatus status)
Description copied from class:AbstractPlatformTransactionManager
Set the given transaction rollback-only. Only called on rollback if the current transaction participates in an existing one.The default implementation throws an IllegalTransactionStateException, assuming that participating in existing transactions is generally not supported. Subclasses are of course encouraged to provide such support.
- Overrides:
doSetRollbackOnly
in classAbstractPlatformTransactionManager
- Parameters:
status
- the status representation of the transaction
doCleanupAfterCompletion
protected void doCleanupAfterCompletion(Object transaction)
Description copied from class:AbstractPlatformTransactionManager
Cleanup resources after transaction completion.Called after
doCommit
anddoRollback
execution, on any outcome. The default implementation does nothing.Should not throw any exceptions but just issue warnings on errors.
- Overrides:
doCleanupAfterCompletion
in classAbstractPlatformTransactionManager
- Parameters:
transaction
- transaction object returned bydoGetTransaction
disconnectOnCompletion
protected void disconnectOnCompletion(Session session)
Disconnect a pre-existing Hibernate Session on transaction completion, returning its database connection but preserving its entity state.The default implementation simply calls
Session.disconnect()
. Subclasses may override this with a no-op or with fine-tuned disconnection logic.- Parameters:
session
- the Hibernate Session to disconnect- Since:
- 4.1.2
- See Also:
Session.disconnect()
isSameConnectionForEntireSession
protected boolean isSameConnectionForEntireSession(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.The default implementation checks the Session's connection release mode to be "on_close".
- Parameters:
session
- the Hibernate Session to check- See Also:
TransactionContext.getConnectionReleaseMode()
,ConnectionReleaseMode.ON_CLOSE
convertHibernateAccessException
protected DataAccessException convertHibernateAccessException(HibernateException ex)
Convert the given HibernateException to an appropriate exception from theorg.springframework.dao
hierarchy.Will automatically apply a specified SQLExceptionTranslator to a Hibernate JDBCException, else rely on Hibernate's default translation.
- Parameters:
ex
- HibernateException that occurred- Returns:
- a corresponding DataAccessException
- See Also:
SessionFactoryUtils.convertHibernateAccessException(org.hibernate.HibernateException)
