Public Constructors

public SpringLobCreatorSynchronization (LobCreator lobCreator)

Create a SpringLobCreatorSynchronization for the given LobCreator.

Parameters
lobCreator the LobCreator to close after transaction completion

Public Methods

public void afterCompletion (int status)

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.

Parameters
status completion status according to the STATUS_* constants

public void beforeCompletion ()

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.

public int getOrder ()

Return the order value of this object, with a higher value meaning greater in terms of sorting.

Normally starting with 0, with Integer.MAX_VALUE indicating the greatest value. Same order values will result in arbitrary positions for the affected objects.

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

Returns
  • the order value
