实例化ConfigurationClassPostProcessor后置处理器ConfigurationClassPostProcessor.postProcessBeanDefinitionRegistry()
postProcessBeanDefinitionRegistry(){ 获得当前的beandfination 标记为是full类型还是lite类型 获得配置类中的commonscan将扫描到的放入BeanDefinitionMap处理importselect类型放入BeanDefinitionMap}
invokeBeanFactoryPostProcessors
将我们传递进来的配置类注册进BeanFactory的BeanDefinitionMap
处理实现类型为BeanDefinitionRegistryPostProcessor、BeanFactoryPostProcessor接口的后置处理器
