Field Detail

• LOB_CREATOR_SYNCHRONIZATION_ORDER

  public static final int LOB_CREATOR_SYNCHRONIZATION_ORDER

Constructor Detail

• SpringLobCreatorSynchronization

  public SpringLobCreatorSynchronization​(LobCreator lobCreator)

  Create a SpringLobCreatorSynchronization for the given LobCreator.

  Parameters:

  lobCreator - the LobCreator to close after transaction completion

Method Detail

• getOrder

  public int getOrder()

  Description copied from interface: Ordered
  Get the order value of this object.

  Higher values are interpreted as lower priority. As a consequence, the object with the lowest value has the highest priority (somewhat analogous to Servlet load-on-startup values).

  Same order values will result in arbitrary sort positions for the affected objects.

  Specified by:

  getOrder in interface Ordered

  Overrides:

  getOrder in class TransactionSynchronizationAdapter

  Returns:

  the order value

  See Also:

  Ordered.HIGHEST_PRECEDENCE, Ordered.LOWEST_PRECEDENCE

• beforeCompletion

  public void beforeCompletion()

  Description copied from interface: TransactionSynchronization
  Invoked before transaction commit/rollback. Can perform resource cleanup before transaction completion.

  This method will be invoked after beforeCommit, even when beforeCommit threw an exception. This callback allows for closing resources before transaction completion, for any outcome.

  Specified by:

  beforeCompletion in interface TransactionSynchronization

  Overrides:

  beforeCompletion in class TransactionSynchronizationAdapter

  See Also:

  TransactionSynchronization.beforeCommit(boolean), TransactionSynchronization.afterCompletion(int)

• afterCompletion

  public void afterCompletion​(int status)

  Description copied from interface: TransactionSynchronization
  Invoked after transaction commit/rollback. Can perform resource cleanup after transaction completion.

  NOTE: The transaction will have been committed or rolled back already, but the transactional resources might still be active and accessible. As a consequence, any data access code triggered at this point will still "participate" in the original transaction, allowing to perform some cleanup (with no commit following anymore!), unless it explicitly declares that it needs to run in a separate transaction. Hence: Use PROPAGATION_REQUIRES_NEW for any transactional operation that is called from here.

  Specified by:

  afterCompletion in interface TransactionSynchronization

  Overrides:

  afterCompletion in class TransactionSynchronizationAdapter

  Parameters:

  status - completion status according to the STATUS_* constants

  TransactionSynchronization.STATUS_COMMITTED, TransactionSynchronization.STATUS_ROLLED_BACK, TransactionSynchronization.STATUS_UNKNOWN, TransactionSynchronization.beforeCompletion()
