Comment utiliser les tâches planifiées de Spring Boot

@Componentpublic class GetIndexInfo {    public final static long ONE_Minute =  60 * 1000;    /*当任务执行完毕后1分钟在执行*/
    @Scheduled(fixedDelay=ONE_Minute)    public void fixedDelayJob(){
        System.out.println("---------------1-----------------");
        System.out.println(new Date().getTime());
    }    /*每多次分钟一次*/
    @Scheduled(fixedRate=ONE_Minute)    public void fixedRateJob(){
        System.out.println("---------------2-----------------");
        System.out.println(new Date().getTime());
    }    /*每周日凌晨三点执行*/
    @Scheduled(cron="0 10 3 ? * 1")    public void cronJob(){
        System.out.println("---------------3-----------------");
        System.out.println(new Date().getTime());
