我对 Spring 完全陌生,并开始从这个网站做官方指南: https ://spring.io/guides
我想做这个指南: https ://spring.io/guides/gs/scheduling- tasks/
我得到以下异常:

应用程序入门类是这样的:
@ComponentScan @EnableAutoConfiguration public class Application { public static void main(String[] args) { SpringApplication.run(ScheduledTasks.class, args); } }
如您所见, main 方法包含一个注释行。我已经完成了一个教程,即这个:https://spring.io/guides/gs/sumption- rest/ 它已经启动并运行。但我无法运行 ScheduledTasks 应用程序,如下所示:
@EnableScheduling public class ScheduledTasks { private static final SimpleDateFormat dateFormat = new SimpleDateFormat("HH:mm:ss"); @Scheduled(fixedRate = 5000) public void reportCurrentTime() { System.out.println("The time is now " + dateFormat.format(new Date())); } }
我使用 Eclipse 并将 Application.java 的 main 作为应用程序运行。有人可以帮我吗?
调度指南不是 Web 应用程序,因此您可能在 REST 指南中的 pom.xml 中有一些发霉的东西?如果您严格按照说明操作,它应该可以工作。您在上面发布的代码的另一个潜在问题是您的@EnableAutoConfiguration类没有在上下文中使用,仅用作主要方法(这对于调度指南可能不是问题,但可能是其他许多人的问题)。
@EnableAutoConfiguration
