如何解析@Component,@Service,@Configurationd,@Bean,@Import等注解
1. 源码描述
BeanFactoryPostProcessor used for bootstrapping processing of @Configuration classes.
Registered by default when using context:annotation-config/ or context:component-scan/. Otherwise, may be declared manually as with any other BeanFactoryPostProcessor.
This post processor is priority-ordered as it is important that any Bean methods declared in @Configuration classes have their corresponding bean definitions registered before any other BeanFactoryPostProcessor executes.
主要是来解析@Configuration注解的类，比其他BeanFactoryPostProcessor优先执行。
