org.hibernate.context .JTASessionContext

JTASessionContext
public class JTASessionContext implements CurrentSessionContext(Code)
	An implementation of CurrentSessionContext which scopes the notion of a current session to a JTA transaction. Because JTA gives us a nice tie-in to clean up after ourselves, this implementation will generate Sessions as needed provided a JTA transaction is in effect. If a session is not already associated with the current JTA transaction at the time JTASessionContext.currentSession() is called, a new session will be opened and it will be associated with that JTA transaction. Note that the sessions returned from this method are automatically configured with both the org.hibernate.cfg.Environment.FLUSH_BEFORE_COMPLETION auto-flush and org.hibernate.cfg.Environment.AUTO_CLOSE_SESSION auto-close attributes set to true, meaning that the Session will be automatically flushed and closed as part of the lifecycle for the JTA transaction to which it is associated. Additionally, it will also be configured to aggressively release JDBC connections after each statement is executed. These settings are governed by the JTASessionContext.isAutoFlushEnabled() , JTASessionContext.isAutoCloseEnabled() , and JTASessionContext.getConnectionReleaseMode() methods; these are provided (along with the JTASessionContext.buildOrObtainSession() method) for easier subclassing for custom JTA-based session tracking logic (like maybe long-session semantics). author: Steve Ebersole

Method Detail

buildOrObtainSession
protected Session buildOrObtainSession()(Code)
	Strictly provided for subclassing purposes; specifically to allow long-session support. This implementation always just opens a new session. the built or (re)obtained session.

currentSession
public Session currentSession() throws HibernateException(Code)

getConnectionReleaseMode
protected ConnectionReleaseMode getConnectionReleaseMode()(Code)
	Mainly for subclass usage. This impl always returns after_statement. The connection release mode for any built sessions.

isAutoCloseEnabled
protected boolean isAutoCloseEnabled()(Code)
	Mainly for subclass usage. This impl always returns true. Whether or not the the session should be closed by transaction completion.

isAutoFlushEnabled
protected boolean isAutoFlushEnabled()(Code)
	Mainly for subclass usage. This impl always returns true. Whether or not the the session should be flushed prior transaction completion.
