1. ReactiveWebServerApplicationContext#onRefresh
2. ReactiveWebServerApplicationContext#createWebServer

private void createWebServer() {
		WebServerManager serverManager = this.serverManager;
		if (serverManager == null) {
			StartupStep createWebServer = this.getApplicationStartup().start("spring.boot.webserver.create");
			String webServerFactoryBeanName = getWebServerFactoryBeanName();
			ReactiveWebServerFactory webServerFactory = getWebServerFactory(webServerFactoryBeanName);
			createWebServer.tag("factory", webServerFactory.getClass().toString());
			boolean lazyInit = getBeanFactory().getBeanDefinition(webServerFactoryBeanName).isLazyInit();
			this.serverManager = new WebServerManager(this, webServerFactory, this::getHttpHandler, lazyInit); //【1】
			getBeanFactory().registerSingleton("webServerGracefulShutdown",
					new WebServerGracefulShutdownLifecycle(this.serverManager.getWebServer()));
			getBeanFactory().registerSingleton("webServerStartStop",
					new WebServerStartStopLifecycle(this.serverManager));  //【2】
			createWebServer.end();
		}
		initPropertySources();
}

1. 【1】 创建一个 WebServerManager
2. 【2】 封装到： WebServerStartStopLifecycle， 让外围流程控制启动顺序：

@Override
public int getPhase() {
  return Integer.MAX_VALUE - 1;
}
