任务调度 Quartz 学习（二） CronTrigger

public class MyJob implements Job{

    @Override
    public void execute(JobExecutionContext jobExecutionContext) throws JobExecutionException {
        System.out.println("测试quartz"+new Date());
    }

    //CronTrigger
    //其他定义与SimpleTrigger没有区别，只是在定义Trigger的时候有所改变
    public static void cronTrigger() throws SchedulerException {
        SchedulerFactory sf=new StdSchedulerFactory();
        Scheduler sche=sf.getScheduler();

        JobDetail jobDetail=JobBuilder.newJob(MyJob.class).withIdentity("job2","group2").build();
        CronTrigger cron=TriggerBuilder.newTrigger().withIdentity("trigger2","group2")
                .startNow()
                .withSchedule(CronScheduleBuilder.cronSchedule("0/20 * * * * ?")).build();  //每隔20秒运行一次
                                                                                            //("15 0/2 * * * ?")偶数分钟的第15秒执行一次
                                                                                            //("0 0/2 8-17 * * ?")8时到17时的每个偶数分钟执行一次
                                                                                            //("0 0/3 17-23 * * ?")17-23时，每3分钟执行一次

        sche.scheduleJob(jobDetail,cron);
        sche.start();


    }

    public static void main(String[] args) throws SchedulerException {
