Method Summary

Modifier and Type	Method	Description
default String	getTransactionName()	Return the defined name of the transaction (possibly an empty String).
default 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.
default boolean	isCompleted()	Return whether this transaction is completed, that is, whether it has already been committed or rolled back.
default boolean	isNested()	Return if this transaction executes in a nested fashion within another.
default 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.
default boolean	isReadOnly()	Return if this transaction is defined as read-only transaction.
default boolean	isRollbackOnly()	Return whether the transaction has been marked as rollback-only (either by the application or by the transaction infrastructure).
default void	setRollbackOnly()	Set the transaction rollback-only.

Method Details

getTransactionName

default String getTransactionName()

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.

Since:

6.1

• TransactionDefinition.getName()

hasTransaction

default 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.

The default implementation returns true.

Since:

6.1

• isNewTransaction()
• isNested()
• isReadOnly()

isNewTransaction

default 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.

This is primarily here for transaction manager state handling. Prefer the use of 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 isNested().

The default implementation returns true.

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

isNested

default boolean isNested()

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

The default implementation returns false.

Since:

6.1

See Also:

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

isReadOnly

default boolean isReadOnly()

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

The default implementation returns false.

Since:

6.1

See Also:

• TransactionDefinition.isReadOnly()

setRollbackOnly

default void setRollbackOnly()

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.

See Also:

• isRollbackOnly()

isRollbackOnly

default boolean isRollbackOnly()

Return whether the transaction has been marked as rollback-only (either by the application or by the transaction infrastructure).

The default implementation returns false.

See Also:

• setRollbackOnly()

isCompleted

default boolean isCompleted()

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

The default implementation returns false.
