定时任务(corn job)

cronjob框架

spring Schedule

单机版

在Spring Boot的main主类中加入@EnableScheduling注解，启用定时任务的配置

@Component
// @EnableScheduling
public class ScheduledTasks {
    private static final SimpleDateFormat dateFormat = new SimpleDateFormat("HH:mm:ss");
    @Scheduled(fixedRate = 5000)
    public void reportCurrentTime() {
        System.out.println("现在时间：" + dateFormat.format(new Date()));
    }
}
