springboot CommandLineRunner接口实现自动任务加载功能

CommandLineRunner接口可以实现任务的自动加载，当项目启动完后，就会自动去执行CommandLineRunner接口里的run方法，你可以实现多个CommandLineRunner的实例，使用order来控制执行的顺序！

/**
 * 项目启动后自动运行的代码CommandLineRunner
 */
@Component
@Order(1)
public class MyStartupRunner1 implements CommandLineRunner {
  private Logger logger = LoggerFactory.getLogger(MyStartupRunner1.class);
  @Override
  public void run(String... args) throws Exception {
    logger.info("MyStartupRunner1里的数据");
  }
}
@Component
@Order(2)
public class MyStartupRunner2 implements CommandLineRunner {
  private Logger logger = LoggerFactory.getLogger(MyStartupRunner1.class);
  @Override
  public void run(String... args) throws Exception {
    logger.info("MyStartupRunner2里的数据");
  }
}

程序在启动之后，可以看到控制台的日志，它们被执行了。
