public class MyJob implements Job {
        public void execute(JobExecutionContext jobExecutionContext) throws JobExecutionException {
                System.out.println(new Date() + ": doing something...");
        }
}

class Test {
        public static void main(String[] args) {
                //1、创建JobDetial对象
                JobDetail jobDetail = new JobDetail();
                //设置工作项

                try {

                        scheduler.scheduleJob(jobDetail, strigger);
                        //4、并执行启动、关闭等操作
                        scheduler.start();

                } catch (SchedulerException e) {
                        e.printStackTrace();
                }
//                try {
//                         //关闭调度器
//                        scheduler.shutdown(true);
//                } catch (SchedulerException e) {
//                        e.printStackTrace();
//                }
        }
