application.yaml中配置

spring:
  main:
      web-application-type: none

保持运行：加入Thread.currentThread().join();

最终得到如下结构

@SpringBootApplication
public class Application implements CommandLineRunner {
  public static void main(String[] args) {
      SpringApplication.run(Application.class, args);
  }

  @Override
  public void run(String... args) throws Exception {
      。。。
      Thread.currentThread().join();
  }
}
