org.springframework.transaction.support.TransactionSynchronization

All known Subclasses:   org.springframework.transaction.support.TransactionSynchronizationAdapter,
TransactionSynchronization
public interface TransactionSynchronization (Code)
Interface for transaction synchronization callbacks. Supported by AbstractPlatformTransactionManager.

TransactionSynchronization implementations can implement the Ordered interface to influence their execution order. A synchronization that does not implement the Ordered interface is appended to the end of the synchronization chain.

System synchronizations performed by Spring itself use specific order values, allowing for fine-grained interaction with their execution order (if necessary).

Field Summary
 intSTATUS_COMMITTED
    
 intSTATUS_ROLLED_BACK
    
 intSTATUS_UNKNOWN
    


Method Summary
 voidafterCommit()
     Invoked after transaction commit.
 voidafterCompletion(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.

 voidbeforeCommit(boolean readOnly)
     Invoked before transaction commit (before "beforeCompletion"). Can e.g.
 voidbeforeCompletion()
     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.

 voidresume()
     Resume this synchronization.
 voidsuspend()
     Suspend this synchronization.

Field Detail
STATUS_COMMITTED
int STATUS_COMMITTED(Code)
Completion status in case of proper commit



STATUS_ROLLED_BACK
int STATUS_ROLLED_BACK(Code)
Completion status in case of proper rollback



STATUS_UNKNOWN
int STATUS_UNKNOWN(Code)
Completion status in case of heuristic mixed completion or system errors





Method Detail
afterCommit
void afterCommit()(Code)
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.
throws:
  RuntimeException - in case of errors; will be propagated to the caller(note: do not throw TransactionException subclasses here!)




afterCompletion
void afterCompletion(int status)(Code)
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
throws:
  RuntimeException - in case of errors; will be logged but not propagated(note: do not throw TransactionException subclasses here!)
See Also:   TransactionSynchronization.STATUS_COMMITTED
See Also:   TransactionSynchronization.STATUS_ROLLED_BACK
See Also:   TransactionSynchronization.STATUS_UNKNOWN
See Also:   TransactionSynchronization.beforeCompletion




beforeCommit
void beforeCommit(boolean readOnly)(Code)
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.
Parameters:
  readOnly - whether the transaction is defined as read-only transaction
throws:
  RuntimeException - in case of errors; will be propagated to the caller(note: do not throw TransactionException subclasses here!)
See Also:   TransactionSynchronization.beforeCompletion




beforeCompletion
void beforeCompletion()(Code)
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.
throws:
  RuntimeException - in case of errors; will be logged but not propagated(note: do not throw TransactionException subclasses here!)
See Also:   TransactionSynchronization.beforeCommit
See Also:   TransactionSynchronization.afterCompletion




resume
void resume()(Code)
Resume this synchronization. Supposed to rebind resources to TransactionSynchronizationManager if managing any.
See Also:   TransactionSynchronizationManager.bindResource



suspend
void suspend()(Code)
Suspend this synchronization. Supposed to unbind resources from TransactionSynchronizationManager if managing any.
See Also:   TransactionSynchronizationManager.unbindResource
