Package org.springframework.transaction.support

Class TransactionSynchronizationAdapter

java.lang.Object

org.springframework.transaction.support.TransactionSynchronizationAdapter

All Implemented Interfaces:

Flushable, Ordered, TransactionSynchronization

@Deprecated
public abstract class TransactionSynchronizationAdapter
extends Object
implements TransactionSynchronization, Ordered

Deprecated.

as of 5.3, in favor of the default methods on the TransactionSynchronization interface

Simple 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.

public TransactionSynchronizationAdapter()

Deprecated.

Method Details

getOrder

public int getOrder()

Deprecated.

Description copied from interface: TransactionSynchronization

Return the execution order for this transaction synchronization.

Default is Ordered.LOWEST_PRECEDENCE.

Specified by:

getOrder in interface Ordered

Specified by:

getOrder in interface TransactionSynchronization

Returns:

the order value

See Also:

• Ordered.HIGHEST_PRECEDENCE
• Ordered.LOWEST_PRECEDENCE

suspend

public void suspend()

Deprecated.

Description copied from interface: TransactionSynchronization

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

Specified by:

suspend in interface TransactionSynchronization

See Also:

• TransactionSynchronizationManager.unbindResource(java.lang.Object)

resume

public void resume()

Deprecated.

Description copied from interface: TransactionSynchronization

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

Specified by:

resume in interface TransactionSynchronization

See Also:

• TransactionSynchronizationManager.bindResource(java.lang.Object, java.lang.Object)

flush

public void flush()

Deprecated.

Description copied from interface: TransactionSynchronization

Flush the underlying session to the datastore, if applicable: for example, a Hibernate/JPA session.

Specified by:

flush in interface Flushable

Specified by:

flush in interface TransactionSynchronization

See Also:

• TransactionStatus.flush()

beforeCommit

public void beforeCommit(boolean readOnly)

Deprecated.

Description copied from interface: TransactionSynchronization

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.

Specified by:

beforeCommit in interface TransactionSynchronization

Parameters:

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

See Also:

• TransactionSynchronization.beforeCompletion()

beforeCompletion

public void beforeCompletion()

Deprecated.

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

See Also:

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

afterCommit

public void afterCommit()

Deprecated.

Description copied from interface: TransactionSynchronization

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.

Specified by:

afterCommit in interface TransactionSynchronization

afterCompletion

public void afterCompletion(int status)

Deprecated.

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

Parameters:

status - completion status according to the STATUS_* constants

• TransactionSynchronization.STATUS_ROLLED_BACK
