Quartz简单实例

Quartz中提供了两种触发器，分别是CronTrigger和SimpleTrigger。

1. SimpleTrigger

每隔若干毫秒来触发纳入进度的任务。

2. CronTrigger

在特定“格林日历”时刻触发纳入进程的任务。

调度程序如下：

public class TestQuartz {
    public void myTask() throws Exception
    {
        String tim = FileProperties.getMyProperty("Socket_TIM_ZZH");
        System.out.println(tim);
        //定时器任务定义
        Scheduler scheduler = new StdSchedulerFactory().getScheduler();
        scheduler.start();
        //定时器任务
        JobDetail testJob = new JobDetail("testJob", Scheduler.DEFAULT_GROUP, TestTask.class);
        //CronTrigger触发器
        //Trigger trigger = new CronTrigger("testCronTrigger", Scheduler.DEFAULT_GROUP, tim.trim());
        //结束时间
        long end = System.currentTimeMillis() + 9000L;
        //执行10次，每3秒执行一次，到9秒后结束
        SimpleTrigger trigger = new SimpleTrigger("test",null,new Date(),new Date(end),10,3000L);
        // 定时器任务监听
        scheduler.scheduleJob(testJob, trigger);
    }
}

任务执行程序如下：

public class TestTask extends Thread implements Job{
    //private static Logger logger = Logger.getLogger(TestTask.class.getName());
    private static SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
    private Date today = null;
    public TestTask()
    {
        Calendar rightNow   =   Calendar.getInstance();
        rightNow.add(Calendar.DATE,-1);
        this.today = rightNow.getTime();
    }

    @Override
    public void execute(JobExecutionContext arg0) throws JobExecutionException {
        try {
            System.out.println("testTask：" + format.format(this.today) + "------------------------------------");
            //logger.info("testTask：" + format.format(this.today) + "------------------------------------");
        } catch (Exception e) {
            e.printStackTrace();
            //logger.error("error:" + e.getMessage());
        }

    }
}

main函数：

public static void main(String[] args)
    {
        try {
             TestQuartz testQuartz = new TestQuartz();
             testQuartz.myTask();
        }catch(Exception e)
        {
            e.printStackTrace();
        }
    }

除了引入quartz包，还要使用Commons-logging.jar
