知识点： 1：写个jar 需要springboot自动加载， META-INF/spring.factories、 文件里面写你要加载的类 org.springframework.context.ApplicationContextInitializer=
org.springframework.boot.autoconfigure.logging.AutoConfigurationReportLoggingInitializer
Auto Configure
org.springframework.boot.autoconfigure.EnableAutoConfiguration=
org.springframework.boot.autoconfigure.aop.AopAutoConfiguration,\
管理监听
org.springframework.boot.actuate.autoconfigure.ManagementContextConfiguration=
参考文章（https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-developing-auto-configuration.html） 2：/META-INF/spring-configuration-metadata.json 按照spring的文档元数据
