1、this.invokeAwareMethods(beanName, bean);

處理Aware接口的回調

2、 wrappedBean = this.applyBeanPostProcessorsBeforeInitialization(bean, beanName);

後置處理器的調用

3、 this.invokeInitMethods(beanName, wrappedBean, mbd);

調用自定義的初始化方法

4、wrappedBean = this.applyBeanPostProcessorsAfterInitialization(wrappedBean, beanName);

後置處理器的調用
spring源碼09——AbstractAutowireCapableBeanFactory.applyBeanPostProcessorsAfterInitialization

5、return wrappedBean;

返回創建好的Bean:
如果如下方法調用過來的：AbstractApplicationContext.registerBeanPostProcessors()
此時創建的bean是擴展了BeanPostProcessor的bean，比如：AbstractAutoProxyCreator；

如果是從如下方法調用過來的：
AbstractApplicationContext.finishBeanFactoryInitialization
測試創建的bean就是我們常用的bean。

AbstractAutoProxyCreator實現了BeanPostProcessor接口。
