public interface CallbackPreferringPlatformTransactionManager
Extension of the PlatformTransactionManager
interface, exposing a method for executing a given callback within a transaction.
Implementors of this interface automatically express a preference for
callbacks over programmatic getTransaction
, commit
and rollback
calls. Calling code may check whether a given
transaction manager implements this interface to choose to prepare a
callback instead of explicit transaction demarcation control.
Spring's TransactionTemplate
and
TransactionInterceptor
detect and use this PlatformTransactionManager variant automatically.
