/*** @SpringBootApplication来标注一个主程序类,说明这是一个SpringBoot应用*/@SpringBootApplicationpublicclassApplication {publicstaticvoidmain(String[] args) {//Spring应用启动SpringApplication.run(Application.class,args); } } SpringBoot启动分为注解和启动方法两个过程 2. @SpringBootApplication Spring Boo...
一、什么是SpringBoot Spring Boot makes it easy to create stand-alone, production-grade Spring based Applications that you can "just run". We take an opinionated view of the Spring platform and third-party libraries so you can get started with minimum fuss. Most Spring Boot applicati...

所以，Spring Boot Starter 不是通过 SPI 来实现的，是自己实现了一套流程。
··· listeners.finished(context,null);stopWatch.stop();if(this.logStartupInfo){newStartupInfoLogger(this.mainApplicationClass).logStarted(getApplicationLog(),stopWatch);}//整个SpringBoot应用启动完成以后返回启动的ioc容器;returncontext;}catch(Throwableex){handleRunFailure(context,listeners,analyzers,ex...
