package com.yjck.quartz;

import org.quartz.JobDetail;
import org.quartz.Scheduler;
import org.quartz.SchedulerException;
import org.quartz.SimpleTrigger;
import org.quartz.impl.StdSchedulerFactory;
public class QuartzTest {
   public static void main(String[] args) throws InterruptedException {
       QuartzTest tqz = new QuartzTest();
       try {
           tqz.startShedule();
       } catch (SchedulerException e) {
           e.printStackTrace();
       }
   }

   protected void startShedule() throws SchedulerException {
       /* 调度器 */
       Scheduler scheduler = StdSchedulerFactory.getDefaultScheduler();
       /* 具体执行类 */
       JobDetail jobDetail = new JobDetail("firstJOB",
               scheduler.DEFAULT_GROUP, MyJobClass.class);
       // 触发器，定义每3秒执行一次
       // Trigger trigger = TriggerUtils.makeSecondlyTrigger(3);
       /* 简单触发器，相当于java timetask，CronTrigger 是更为发展的触发器，有cron表达式 */
       SimpleTrigger trigger = new SimpleTrigger("triger1",
               scheduler.DEFAULT_GROUP, 10, 2000);
       scheduler.scheduleJob(jobDetail, trigger);
       scheduler.start();
//       scheduler.shutdown();
   }

}

/*事件类，处理具体的业务*/

package com.yjck.quartz;

import java.util.Date;

import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;

public class MyJobClass implements Job{
   /*事件类，处理具体的业务*/
   public void execute(JobExecutionContext job) throws JobExecutionException {
       System.out.println("hello quartz"+ new Date());

   }

}

项目结构如下
