3
忽略一些依赖的接口，注入一些和环境相关的类(非重点)
1
核心refresh()方法
ConfigurationClassPostProcessor#postProcessBeanDefinitionRegistry处理@Configuration，@PropertySources，@ComponentScans，@ComponentScan，@Import
invokeBeanFactoryPostProcessors()调用BeanFactory后置处理器
2
registerBeanPostProcessors()
AnnotationConfigApplicationContext
prepareRefresh()初始化属性配置文件、检验必须属性以及监听器
4
AnnotatedBeanDefinitionReader向容器注册6个后置处理器
ClassPathBeanDefinitionScanner扫描类提供给程序员在外部手动调用
加了@Configuration，标识为full，意为全注解类，对该类会进行cglib代理span style=\"font-size: inherit;\
@import有三种情况1、普通类2、实现ImportSelector3、实现ImportBeanDefinitionRegistrar
prepareBeanFactory(beanFactory)
