Class GenericReactiveTransaction

java.lang.Object

org.springframework.transaction.reactive.GenericReactiveTransaction

All Implemented Interfaces:

ReactiveTransaction, TransactionExecution

public class GenericReactiveTransaction
extends Object
implements ReactiveTransaction

Default implementation of the ReactiveTransaction interface, used by AbstractReactiveTransactionManager. Based on the concept of an underlying "transaction object".

Holds all status information that AbstractReactiveTransactionManager needs internally, including a generic transaction object determined by the concrete transaction manager implementation.

NOTE: This is not intended for use with other ReactiveTransactionManager implementations, in particular not for mock transaction managers in testing environments.

Since:

5.2

Constructor	Description
GenericReactiveTransaction(@Nullable String transactionName, @Nullable Object transaction, boolean newTransaction, boolean newSynchronization, boolean nested, boolean readOnly, boolean debug, @Nullable Object suspendedResources)	Create a new DefaultReactiveTransactionStatus instance.

Method Summary

Modifier and Type	Method	Description
@Nullable Object	getSuspendedResources()	Return the holder for resources that have been suspended for this transaction, if any.
Object	getTransaction()	Return the underlying transaction object.
String	getTransactionName()	Return the defined name of the transaction (possibly an empty String).
boolean	hasTransaction()	Return whether there is an actual transaction active: this is meant to cover a new transaction as well as participation in an existing transaction, only returning false when not running in an actual transaction at all.
boolean	isCompleted()	Return whether this transaction is completed, that is, whether it has already been committed or rolled back.
boolean	isDebug()	Return whether the progress of this transaction is debugged.
boolean	isNested()	Return if this transaction executes in a nested fashion within another.
boolean	isNewSynchronization()	Return if a new transaction synchronization has been opened for this transaction.
boolean	isNewTransaction()	Return whether the transaction manager considers the present transaction as new; otherwise participating in an existing transaction, or potentially not running in an actual transaction in the first place.
boolean	isReadOnly()	Return if this transaction is defined as read-only transaction.
boolean	isRollbackOnly()	Determine the rollback-only flag via checking this ReactiveTransactionStatus.
void	setCompleted()	Mark this transaction as completed, that is, committed or rolled back.

Constructor Details

GenericReactiveTransaction

public GenericReactiveTransaction(@Nullable String transactionName,
 @Nullable Object transaction,
 boolean newTransaction,
 boolean newSynchronization,
 boolean nested,
 boolean readOnly,
 boolean debug,
 @Nullable Object suspendedResources)

Create a new DefaultReactiveTransactionStatus instance.

Parameters:

transactionName - the defined name of the transaction

transaction - underlying transaction object that can hold state for the internal transaction implementation

newTransaction - if the transaction is new, otherwise participating in an existing transaction

newSynchronization - if a new transaction synchronization has been opened for the given transaction

readOnly - whether the transaction is marked as read-only

debug - should debug logging be enabled for the handling of this transaction? Caching it in here can prevent repeated calls to ask the logging system whether debug logging should be enabled.

suspendedResources - a holder for resources that have been suspended for this transaction, if any

Since:

6.1

Method Details

getTransactionName

public String getTransactionName()

Description copied from interface: TransactionExecution

Return the defined name of the transaction (possibly an empty String).

In case of Spring's declarative transactions, the exposed name will be the fully-qualified class name + "." + method name (by default).

The default implementation returns an empty String.

Specified by:

getTransactionName in interface TransactionExecution

See Also:

• TransactionDefinition.getName()

getTransaction

public Object getTransaction()

Return the underlying transaction object.

Throws:

IllegalStateException - if no transaction is active

hasTransaction

public boolean hasTransaction()

Description copied from interface: TransactionExecution

Return whether there is an actual transaction active: this is meant to cover a new transaction as well as participation in an existing transaction, only returning false when not running in an actual transaction at all.

The default implementation returns true.

Specified by:

hasTransaction in interface TransactionExecution

See Also:

• TransactionExecution.isNewTransaction()
• TransactionExecution.isNested()
• TransactionExecution.isReadOnly()

isNewTransaction

public boolean isNewTransaction()

Description copied from interface: TransactionExecution

Return whether the transaction manager considers the present transaction as new; otherwise participating in an existing transaction, or potentially not running in an actual transaction in the first place.

This is primarily here for transaction manager state handling. Prefer the use of TransactionExecution.hasTransaction() for application purposes since this is usually semantically appropriate.

The "new" status can be transaction manager specific, for example, returning true for an actual nested transaction but potentially false for a savepoint-based nested transaction scope if the savepoint management is explicitly exposed (such as on TransactionStatus). A combined check for any kind of nested execution is provided by TransactionExecution.isNested().

The default implementation returns true.

Specified by:

isNewTransaction in interface TransactionExecution

See Also:

• TransactionExecution.hasTransaction()
• TransactionExecution.isNested()
• TransactionStatus.hasSavepoint()

isNewSynchronization

public boolean isNewSynchronization()

Return if a new transaction synchronization has been opened for this transaction.

isNested

public boolean isNested()

Description copied from interface: TransactionExecution

Return if this transaction executes in a nested fashion within another.

The default implementation returns false.

Specified by:

isNested in interface TransactionExecution

See Also:

• TransactionExecution.hasTransaction()
• TransactionExecution.isNewTransaction()
• TransactionDefinition.PROPAGATION_NESTED

isReadOnly

public boolean isReadOnly()

Description copied from interface: TransactionExecution

Return if this transaction is defined as read-only transaction.

The default implementation returns false.

Specified by:

isReadOnly in interface TransactionExecution

See Also:

• TransactionDefinition.isReadOnly()

isDebug

public boolean isDebug()

Return whether the progress of this transaction is debugged. This is used by AbstractReactiveTransactionManager as an optimization, to prevent repeated calls to logger.isDebugEnabled(). Not really intended for client code.

getSuspendedResources

public @Nullable Object getSuspendedResources()

Return the holder for resources that have been suspended for this transaction, if any.

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 this ReactiveTransactionStatus.

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

Specified by:

isRollbackOnly in interface TransactionExecution

See Also:

• TransactionExecution.setRollbackOnly()

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
