关于quartz:quartz简单用法用cron表达式

1.实现Job接口 --你要做什么事？

public class myJob implements Job {    @Autowired    private PileStateManager pileStateManager;    @Override    public void execute(JobExecutionContext arg0) throws JobExecutionException {        //判断以后工夫发送指定费率报文        int hours = new Date().getHours();        if (hours >= 7 && hours < 11) {            System.out.println("我是尖");           // buf.writeBytes(ByteConvertUtil.hourChargeTo2Bytes((int) cachePile.getOneRate()));        } else if (hours >= 19 && hours < 23) {            System.out.println("我是峰");           // buf.writeBytes(ByteConvertUtil.hourChargeTo2Bytes((int) cachePile.getTwoRate()));        } else if (hours >= 11 && hours < 19) {            System.out.println("我是平");            pileStateManager.UpdateChargeRate();            //buf.writeBytes(ByteConvertUtil.hourChargeTo2Bytes((int) cachePile.getThreeRate()));        } else {            System.out.println("我是谷");           // buf.writeBytes(ByteConvertUtil.hourChargeTo2Bytes((int) cachePile.getFourRate()));        }    }

2.Tirgger -触发器 --你什么时候去做
3.Scheduler -任务调度器 --你什么时候须要去做什么事

public class Test {    public void go() throws Exception {        // 首先，必须要获得一个Scheduler的援用        SchedulerFactory sf = new StdSchedulerFactory();        Scheduler sched = sf.getScheduler();        //jobs能够在scheduled的sched.start()办法前被调用        //job 1将每隔20秒执行一次        JobDetail job = newJob(myJob.class).withIdentity("job1", "group1").build();        CronTrigger trigger = newTrigger().withIdentity("trigger1", "group1").withSchedule(cronSchedule("0/20 * * * * ?")).build();        sched.scheduleJob(job, trigger);        // job 2将每2分钟执行一次（在该分钟的第15秒)        job = newJob(myJob.class).withIdentity("job2", "group1").build();        trigger = newTrigger().withIdentity("trigger2", "group1").withSchedule(cronSchedule("15 0/2 * * * ?")).build();        sched.scheduleJob(job, trigger);        // 开始执行，start()办法被调用后，计时器就开始工作，计时调度中容许放入N个Job        sched.start();    }    public static void main(String[] args) throws Exception {        Test test = new Test();        test.go();    }}
