实例：

import java.util.Date;import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;public class SimpleJob implements Job {@Overridepublic void execute(JobExecutionContext jobCtx)throws JobExecutionException {System.out.println(jobCtx.getTrigger().getName() +  " triggered.time.is:" + (new Date()));}
}

import org.quartz.CronExpression;
import org.quartz.CronTrigger;
import org.quartz.JobDetail;
import org.quartz.Scheduler;
import org.quartz.SchedulerFactory;
import org.quartz.impl.StdSchedulerFactory;public class CronTriggerRunner {public static void main(String[] args) {try {//创建一个JobDdtail实例，指定SimpleJob，组名为jgroup1，名称为job1_2JobDetail jobDetail = new JobDetail("job1_2", "jgroup1", SimpleJob.class);//创建CronTrigger，指定组及名称CronTrigger cronTrigger = new CronTrigger("trigger1_2", "tgroup1");//定义Cron表达式，每隔5秒运行一次CronExpression cexp = new CronExpression("0/5 * * * * ?");cronTrigger.setCronExpression(cexp);//通过SchedulerFactory获取一个调度器实例SchedulerFactory schedulerFactory = new StdSchedulerFactory();Scheduler scheduler = schedulerFactory.getScheduler();//注册并进行调度scheduler.scheduleJob(jobDetail, cronTrigger);//调度开始scheduler.start();} catch (Exception e) {e.printStackTrace();}}
}

 运行结果：

trigger1_2 triggered.time.is:Wed Apr 17 16:44:50 CST 2013

trigger1_2 triggered.time.is:Wed Apr 17 16:44:55 CST 2013

trigger1_2 triggered.time.is:Wed Apr 17 16:45:00 CST 2013

trigger1_2 triggered.time.is:Wed Apr 17 16:45:05 CST 2013

默认情况下Cron表达式对应当前的时区，可以通过CronTriggerRunner的setTimeZone(java.util.TimeZone timeZone)方法显式指定时区。用户也可以通过setStartTime(java.util.Date startTime)和setEndTime(java.util.Date endTime)指定开始和结束的时间
