父类GenericApplicationContext构造器初始化DefaultListableBeanFactory

obtainFreshBeanFactory()给beanFactory设置序列化id

自身构造器初始化AnnotatedBeanDefinitionReaderClassPathBeanDefinitionScanner

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)
