有耐心看到这里说明是真的感兴趣，这里就写自己总结的知识点，欢迎随时补充
1springboot不同文件扫描顺序，参考详解一说明
2@SpringBootApplication简化了bean的加载过程，但一般bean都是会先创建ApplicationContext应用上下文对象（可以理解为容器对象，通过接口对不同bean进行装载），类如文中的AnnotationConfigApplicationContext，AnnotationConfigServletWebServerApplicationContext，等等，都是先创建上下文容器对象
3File是所有拦截器的父类，就像Object一样，org.springframework.boot.web.servlet.FilterRegistrationBean中AbstractFilterRegistrationBean包含大多数servlet请求的所需要的拦截器
4配置文件读取过程一般会servlet容器加载和文件本身的循序，控制台日志里包含了所有信息

说明：第9部分是关于oauth2配置相关的执行端口（不好暴露），所以省略了大部分代码

说明：此一步进了端口扫描+通过WebMvcEndpointHandlerMapping映射注入actuator监控，注册JMX监控（主要我是用于JVisualVM实时监控，感兴趣的可以了解下），最后再一次发了个TCP请求，看是否有7001端口配置中心是否连上（没仔细研究源码关于此为啥又会请求一遍），终于完了！
