本文详细解析了Spring框架中AOP代理的创建过程，从AbstractApplicationContext初始化到AnnotationAwareAspectJAutoProxyCreator生成代理类的完整调用链。通过深入源码，揭示了Spring如何在运行时动态创建代理对象，实现面向切面编程。

1，是谁生成的代理类，这里暂且记住是AnnotationAwareAspectJAutoPrxoyCreator这个类来生成的代理类。

2.下面是调用链
**加粗样式(1)AbstractApplicationContext.finishBeanFactoryInitialization(ConfigurableListableBeanFactory)
(2) DefaultListableBeanFactory.preInstantiateSingletons()
(3)AbstractBeanFactory.getBean(String)
(4)AbstractBeanFactory.doGetBean(String, Class, Object[],boolean)
(5)DefaultSingletonBeanRegistry.getSingleton(String, ObjectFactory<?>)
(6)AbstractBeanFactory.lambda$doGetBean $0 (S t r i n g, R o o t B e a n D e f i n i t i o n, O b j e c t []) (7) A b s t r a c t A u t o w i r e C a p a b l e B e a n F a c t o r y . c r e a t e B e a n (S t r i n g, R o o t B e a n D e f i n i t i o n, O b j e c t []) (8) A b s t r a c t A u t o w i r e C a p a b l e B e a n F a c t o r y . d o C r e a t e B e a n (. . .)
