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();}
}
