public class SyncJob implements Job {
    @Override

        System.out.println("---------正在同步---------");

        //创建JobDetail实例，并与SyncJob类绑定（Job执行内容）
        JobDetail jobDetail = JobBuilder.newJob(SyncJob.class).withIdentity("job","group").build();
        //构建Trigger实例，每天凌晨3点执行
        CronTrigger cronTrigger = TriggerBuilder.newTrigger().withIdentity("trigger", "triggerGroup")

        //执行
        scheduler.scheduleJob(jobDetail,cronTrigger);
        scheduler.start();
