public class JTASessionContext extends AbstractCurrentSessionContext
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
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
auto-flush
and
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
isAutoFlushEnabled()
, isAutoCloseEnabled()
, and getConnectionReleaseMode()
methods; these are provided (along with the buildOrObtainSession()
method) for easier
subclassing for custom JTA-based session tracking logic (like maybe long-session semantics).Modifier and Type | Class and Description |
