Method Detail

suspend

public void suspend()

Suspend this synchronization. Supposed to unbind resources from TransactionSynchronizationManager if managing any.

resume

public void resume()

Resume this synchronization. Supposed to rebind resources to TransactionSynchronizationManager if managing any.

beforeCommit

public void beforeCommit(boolean readOnly)

Invoked before transaction commit (before "beforeCompletion"). Can e.g. flush transactional sessions to the database.

Note that exceptions will get propagated to the commit caller and cause a rollback of the transaction.

Parameters:

readOnly - if the transaction is defined as read-only transaction

Throws:

java.lang.RuntimeException - in case of errors

beforeCompletion

public void beforeCompletion()

Invoked before transaction commit/rollback (after "beforeCommit"). Can e.g. perform proper resource cleanup.

Note that exceptions will get propagated to the commit caller and cause a rollback of the transaction.

Throws:

java.lang.RuntimeException - in case of errors

afterCompletion

public void afterCompletion(int status)

Invoked after transaction commit/rollback. Can e.g. perform proper resource cleanup.

Note that exceptions will get propagated to the commit or rollback caller, although they will not influence the outcome of the transaction.

Parameters:

status - completion status according to the STATUS_ constants

Throws:

java.lang.RuntimeException - in case of errors
