public abstract class TransactionSynchronizationAdapter extends Object implements TransactionSynchronization, org.springframework.core.Ordered
TransactionSynchronization adapter containing empty
method implementations, for easier overriding of single methods.
Also implements the Ordered interface to enable the execution
order of synchronizations to be controlled declaratively. The default
order is Ordered.LOWEST_PRECEDENCE, indicating
late execution; return a lower value for earlier execution.

TransactionSynchronizationThis 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.

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

TransactionSynchronizationCan 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.
