Class SessionFactoryManagerImpl

java.lang.Object

ch.tocco.nice2.persist.core.impl.hibernate.session.SessionFactoryManagerImpl

All Implemented Interfaces:

ThreadHandlerListener, SessionFactoryManager

@Component
public class SessionFactoryManagerImpl
extends Object
implements SessionFactoryManager, ThreadHandlerListener

This class manages the Session lifecycle for both the old (ContextManagerAdapter) and new (PersistenceServiceImpl) persistence API. This makes it possible to use both APIs together. This class contains the 'implicit' session in a ThreadLocal. The implicit session is created automatically when the persistence API is accessed for the first time in a thread (unless another session is opened explicitly before that). At the end of each request, the implicit session is closed and removed using a ThreadHandlerListener. Sessions created by this class are always bound to the current thread. Also a SessionEventListener is added which detaches the new session from the thread and re-attached the previous session (if present) when the new session is closed.

Method Details

setListeners

@Autowired
public void setListeners(org.springframework.beans.factory.ObjectProvider<SessionFactoryManagerListener> listeners)

threadIsCleaningUp

public void threadIsCleaningUp()

Specified by:

threadIsCleaningUp in interface ThreadHandlerListener

getCurrentSession

public PersistenceSessionImplementor getCurrentSession()

Description copied from interface: SessionFactoryManager

Returns the Session that is bound to the current thread. If no session is bound to the current thread, the implicit session is created (if it does not exist yet) and returned.

Specified by:

getCurrentSession in interface SessionFactoryManager

clearImplicitSession

public void clearImplicitSession()

Specified by:

clearImplicitSession in interface SessionFactoryManager

getImplicitSession

@Nullable
public @Nullable PersistenceSessionImplementor getImplicitSession()

Description copied from interface: SessionFactoryManager

Returns the implicit Session for the current thread. This may return null if the implicit session has not been initialized yet.

Specified by:

getImplicitSession in interface SessionFactoryManager

createNewSession

public PersistenceSessionImplementor createNewSession()

Description copied from interface: SessionFactoryManager

Creates and returns a new Session. The new session will automatically bound to the current thread. If this session will be closed, it will automatically be detached from the current thread and it is attempted to re-attach the previous session.

Specified by:

createNewSession in interface SessionFactoryManager

createNewSession

public PersistenceSessionImplementor createNewSession(@Nullable
 @Nullable Connection connection)

Specified by:

createNewSession in interface SessionFactoryManager

createNewSession

public PersistenceSessionImplementor createNewSession(@Nullable
 @Nullable Integer queryTimeout)

Specified by:

createNewSession in interface SessionFactoryManager

createNewSession

public PersistenceSessionImplementor createNewSession(@Nullable
 @Nullable Connection connection,
 @Nullable
 @Nullable Integer queryTimeout)

Specified by:

createNewSession in interface SessionFactoryManager

attachSessionToThread

public void attachSessionToThread(PersistenceSessionImplementor session)

Description copied from interface: SessionFactoryManager

Bind the given Session to the current thread.

Specified by:

attachSessionToThread in interface SessionFactoryManager

detachSessionFromThread

public void detachSessionFromThread(PersistenceSessionImplementor session)

Description copied from interface: SessionFactoryManager

Detach the given Session from the current thread.

Specified by:

detachSessionFromThread in interface SessionFactoryManager

isAttachedToThread

public boolean isAttachedToThread(PersistenceSessionImplementor session)

Specified by:

isAttachedToThread in interface SessionFactoryManager

Returns:

true if the given Session is bound to the current thread.

closeSession

public void closeSession(PersistenceSessionImplementor session)

Description copied from interface: SessionFactoryManager

Invokes SessionFactoryManagerListener instances and then closes the Session. All sessions should be closed through this method.

Specified by:

closeSession in interface SessionFactoryManager

addListener

public void addListener(SessionFactoryManagerListener listener)

Specified by:

addListener in interface SessionFactoryManager

removeListener

public void removeListener(SessionFactoryManagerListener listener)

Specified by:

removeListener in interface SessionFactoryManager

loadEntityClassByName

public <T extends Entity> Class<T> loadEntityClassByName(String entityName)

Specified by:

loadEntityClassByName in interface SessionFactoryManager

setDefaultQueryTimeout

@Value("${nice2.persist.defaultQueryTimeout}")
public void setDefaultQueryTimeout(int defaultQueryTimeout)
