Class AbstractTransactionStatus

java.lang.Object

org.springframework.transaction.support.AbstractTransactionStatus

All Implemented Interfaces:

Flushable, SavepointManager, TransactionExecution, TransactionStatus

Direct Known Subclasses:

DefaultTransactionStatus, SimpleTransactionStatus

public abstract class AbstractTransactionStatus
extends Object
implements TransactionStatus

Abstract base implementation of the TransactionStatus interface.

Pre-implements the handling of local rollback-only and completed flags, and delegation to an underlying SavepointManager. Also offers the option of a holding a savepoint within the transaction.

Does not assume any specific internal transaction handling, such as an underlying transaction object, and no transaction synchronization mechanism.

Since:

1.2.3

public AbstractTransactionStatus()

Method Details

setRollbackOnly

public void setRollbackOnly()

Description copied from interface: TransactionExecution

Set the transaction rollback-only. This instructs the transaction manager that the only possible outcome of the transaction may be a rollback, as alternative to throwing an exception which would in turn trigger a rollback.

The default implementation throws an UnsupportedOperationException.

Specified by:

setRollbackOnly in interface TransactionExecution

See Also:

• TransactionExecution.isRollbackOnly()

isRollbackOnly

public boolean isRollbackOnly()

Determine the rollback-only flag via checking both the local rollback-only flag of this TransactionStatus and the global rollback-only flag of the underlying transaction, if any.

Specified by:

isRollbackOnly in interface TransactionExecution

See Also:

• isLocalRollbackOnly()
• isGlobalRollbackOnly()

isLocalRollbackOnly

public boolean isLocalRollbackOnly()

Determine the rollback-only flag via checking this TransactionStatus.

Will only return "true" if the application called setRollbackOnly on this TransactionStatus object.

isGlobalRollbackOnly

public boolean isGlobalRollbackOnly()

Template method for determining the global rollback-only flag of the underlying transaction, if any.

This implementation always returns false.

setCompleted

public void setCompleted()

Mark this transaction as completed, that is, committed or rolled back.

isCompleted

public boolean isCompleted()

Description copied from interface: TransactionExecution

Return whether this transaction is completed, that is, whether it has already been committed or rolled back.

The default implementation returns false.

Specified by:

isCompleted in interface TransactionExecution

hasSavepoint

public boolean hasSavepoint()

Description copied from interface: TransactionStatus

Return whether this transaction internally carries a savepoint, that is, has been created as nested transaction based on a savepoint.

This method is mainly here for diagnostic purposes, alongside TransactionExecution.isNewTransaction(). For programmatic handling of custom savepoints, use the operations provided by SavepointManager.

The default implementation returns false.

Specified by:

hasSavepoint in interface TransactionStatus

See Also:

• TransactionExecution.isNewTransaction()
• SavepointManager.createSavepoint()
• SavepointManager.rollbackToSavepoint(Object)
• SavepointManager.releaseSavepoint(Object)

setSavepoint

protected void setSavepoint(@Nullable Object savepoint)

Set a savepoint for this transaction. Useful for PROPAGATION_NESTED.

See Also:

• TransactionDefinition.PROPAGATION_NESTED

getSavepoint

protected @Nullable Object getSavepoint()

Get the savepoint for this transaction, if any.

createAndHoldSavepoint

public void createAndHoldSavepoint()
                            throws TransactionException

Create a savepoint and hold it for the transaction.

Throws:

NestedTransactionNotSupportedException - if the underlying transaction does not support savepoints

TransactionException

See Also:

• SavepointManager.createSavepoint()

rollbackToHeldSavepoint

public void rollbackToHeldSavepoint()
                             throws TransactionException

Roll back to the savepoint that is held for the transaction and release the savepoint right afterwards.

Throws:

TransactionException

See Also:

• SavepointManager.rollbackToSavepoint(Object)
• SavepointManager.releaseSavepoint(Object)

releaseHeldSavepoint

public void releaseHeldSavepoint()
                          throws TransactionException

Release the savepoint that is held for the transaction.

Throws:

TransactionException

See Also:

• SavepointManager.releaseSavepoint(Object)

createSavepoint

public Object createSavepoint()
                       throws TransactionException

This implementation delegates to a SavepointManager for the underlying transaction, if possible.

Specified by:

createSavepoint in interface SavepointManager

Returns:

a savepoint object, to be passed into SavepointManager.rollbackToSavepoint(Object) or SavepointManager.releaseSavepoint(Object)

Throws:

TransactionException - if the savepoint could not be created, for example because the transaction is not in an appropriate state

See Also:

• getSavepointManager()
• SavepointManager.createSavepoint()

rollbackToSavepoint

public void rollbackToSavepoint(Object savepoint)
                         throws TransactionException

This implementation delegates to a SavepointManager for the underlying transaction, if possible.

Specified by:

rollbackToSavepoint in interface SavepointManager

Parameters:

savepoint - the savepoint to roll back to

Throws:

TransactionException - if the rollback failed

See Also:

• getSavepointManager()
• SavepointManager.rollbackToSavepoint(Object)

releaseSavepoint

public void releaseSavepoint(Object savepoint)
                      throws TransactionException

This implementation delegates to a SavepointManager for the underlying transaction, if possible.

Specified by:

releaseSavepoint in interface SavepointManager

Parameters:

savepoint - the savepoint to release

Throws:

TransactionException - if the release failed

See Also:

• getSavepointManager()
• SavepointManager.releaseSavepoint(Object)

getSavepointManager

protected SavepointManager getSavepointManager()

Return a SavepointManager for the underlying transaction, if possible.

Default implementation always throws a NestedTransactionNotSupportedException.

Throws:

NestedTransactionNotSupportedException - if the underlying transaction does not support savepoints
