public interface CallbackPreferringPlatformTransactionManager extends PlatformTransactionManager
Extension of thePlatformTransactionManager
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
androllback
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
andTransactionInterceptor
detect and use this PlatformTransactionManager variant automatically.- Since:
