Invoked after transaction commit. Can perform further operations right after the main transaction has successfully committed.
Can e.g. commit further operations that are supposed to follow on a successful commit of the main transaction, like confirmation messages or emails.
NOTE: The transaction will have been committed 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.
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

status | completion status according to the STATUS_* constants |
---|
Invoked before transaction commit (before "beforeCompletion"). Can e.g. flush transactional O/R Mapping sessions to the database.
This callback does not mean that the transaction will actually be committed. A rollback decision can still occur after this method has been called. This callback is rather meant to perform work that's only relevant if a commit still has a chance to happen, such as flushing SQL statements to the database.
Note that exceptions will get propagated to the commit caller and cause a rollback of the transaction.
readOnly | whether the transaction is defined as read-only transaction |
---|
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.
Flush the underlying session to the datastore, if applicable: for example, a Hibernate/JPA session.
Resume this synchronization. Supposed to rebind resources to TransactionSynchronizationManager if managing any.
Suspend this synchronization. Supposed to unbind resources from TransactionSynchronizationManager if managing any.
Perform a cleanup on the given resource (which is left bound to the thread).

After-commit callback for the given resource holder.
Only called when the resource hasn't been released yet
(shouldReleaseBeforeCompletion()
).

Release the given resource (after it has been unbound from the thread).

Return whether this holder's resource should be released before
transaction completion (true
) or rather after
transaction completion (false
).
Note that resources will only be released when they are
unbound from the thread (shouldUnbindAtCompletion()
).
The default implementation returns true
.
Return whether this holder should be unbound at completion (or should rather be left bound to the thread after the transaction).
The default implementation returns true
