Almost confused the Transactional annotation

Add the following Service and Transactional annotations to my Srping business layer today:

@Service
@Scope(BeanDefinition.SCOPE_SINGLETON)
@Transactional(propagation=Propagation.REQUIRED,
               timeout=600, 
               rollbackFor=Exception.class)

The result always does not recognize propagation, timeout and rollbackFor. Later, I found out that I introduced the wrong class definition. I should have used Spring's org.springframework.transaction.annotation.Transactional , but JavaEE was introduced for CDI (Contexts and Dependency Injection for the Java EE platform, context and dependency injection) bean's javax.transaction.Transactional , it's really easy to get confused if you don't pay attention.
