interface-based proxies。使用Java interface-based proxies时AnnotationAwareAspectJAutoProxyCreatorAnnotationAwareAspectJAutoProxyCreator是一个BeanPostProcessor实现类。使用CGLIB也是注册AnnotationAwareAspectJAutoProxyCreator并且将proxyTargetClasstrue如下AopConfigUtils.forceAutoProxyCreatorToUseClassProxying() AnnotationAwareAspectJAutoProxyCreator.wrapIfNecessary() AnnotationAwareAspectJAutoProxyCreator是一个BeanPostProcessor实现类它的相应方法会在容器管理每个对象实例化不同阶段会执行。wrapIfNecessary()方法在postProcessAfterInitialization()方法调用主要是判断实例化对象是否容器所有Advisor所要作用对象如Transactional标识的方法或类的对象匹配BeanFactoryTransactionAttributeSourceAdvisor。 AnnotationTransactionAttributeSource.determineTransactionAttribute() 判断传入的方法是否含Transactional标识返回TransactionAttribute
