      org.springframework.transaction.annotation.AnnotationTransactionAttributeSource

All Implemented Interfaces:

public class AnnotationTransactionAttributeSource
extends AbstractFallbackTransactionAttributeSource
implements Serializable

Implementation of TransactionAttributeSource for working with transaction metadata in JDK 1.5+ annotation format.

This class reads the JDK 1.5+ Transactional annotation and exposes corresponding transaction attributes to Spring's transaction infrastructure.

This is a direct alternative to AttributesTransactionAttributeSource, which is able to read in source-level attributes via Commons Attributes.

Since:

1.2

Colin Sampaleanu, Juergen Hoeller
