Class JTASessionContext

java.lang.Object
org.hibernate.context.spi.AbstractCurrentSessionContext
org.hibernate.context.internal.JTASessionContext
All Implemented Interfaces:
Serializable, CurrentSessionContext
public class JTASessionContext extends AbstractCurrentSessionContext
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 currentSession() is called, a new session is opened and is associated with the JTA transaction.

Note that the sessions returned from this method are automatically configured with both the properties "hibernate.transaction.flush_before_completion" and "hibernate.transaction.auto_close_session" set to true, meaning that the session will be automatically flushed and closed as part of the lifecycle of the JTA transaction with which it is associated. Additionally, it will be configured to aggressively release JDBC connections after each statement is executed. These settings are governed by the isAutoFlushEnabled(), isAutoCloseEnabled(), and getConnectionHandlingMode() methods; these are provided (along with the buildOrObtainSession() method) for easier subclassing for custom JTA-based session tracking logic (like maybe long-session semantics).

    • currentSession

      public Session currentSession() throws HibernateException
      Description copied from interface: CurrentSessionContext
      Retrieve the current session according to the scoping defined by this implementation.
      Returns:
      The current session.
      Throws:
      HibernateException - Typically indicates an issue locating or creating the current session.

    • buildOrObtainSession

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

    • isAutoCloseEnabled

      protected boolean isAutoCloseEnabled()
      Mainly for subclass usage. This impl always returns true.
      Returns:
      Whether the session should be closed by transaction completion.

    • isAutoFlushEnabled

      protected boolean isAutoFlushEnabled()
      Mainly for subclass usage. This impl always returns true.
      Returns:
      Whether the session should be flushed prior transaction completion.

    • getConnectionHandlingMode

      protected PhysicalConnectionHandlingMode getConnectionHandlingMode()
      Mainly for subclass usage. This impl always returns after_statement.
      Returns:
      The connection release mode for any built sessions.
