@SpringBootApplication
public class DemoApplication {

	public static void main(String[] args) throws Exception {
		ConfigurableApplicationContext application = SpringApplication.run(DemoApplication.class, args);
		Environment env = application.getEnvironment();
		String ip = InetAddress.getLocalHost().getHostAddress();
		String port = env.getProperty("server.port");
		String property = env.getProperty("server.servlet.context-path");
		String path = property == null ? "" :  property;
		System.out.println(
				"\n\t" +
				"----------------------------------------------------------\n\t" +
				"Application Sailrui-Boot is running! Access URLs:\n\t" +
				"Local: \t\thttp://localhost:" + port + path + "/\n\t" +
				"External: \thttp://" + ip + ":" + port + path + "/\n\t" +
				"------------------------------------------------------------");
	}
