让我们继续用第一个例子中StringTest.
1.来写一个每隔10秒启动一次任务的例子.
import java.util.Date;
import org.quartz.JobDetail;
import org.quartz.Scheduler;
import org.quartz.SchedulerFactory;
import org.quartz.SimpleTrigger;
import org.quartz.impl.StdSchedulerFactory;
public class SimpleTriggerTest
{
public static void main(String[] args) throws Exception
{
SchedulerFactory schedulerFactory = new StdSchedulerFactory();
Scheduler scheduler = schedulerFactory.getScheduler();
// 系统当前时间10秒后
long startTime = System.currentTimeMillis() + 10000L;
SimpleTrigger trigger = new SimpleTrigger("myTrigger", null, new Date(
startTime), null, 0, 0L);
JobDetail jobDetail = new JobDetail();
jobDetail.setJobClass(StringTest.class);
jobDetail.setName("test");
jobDetail.setGroup("A");
scheduler.scheduleJob(jobDetail, trigger);
scheduler.start();
}
}
2.创建一个触发器,立即启动,每隔60秒,启动一次.
SimpleTrigger trigger = new SimpleTrigger("myTrigger",
null,
new Date(),
null,
SimpleTrigger.REPEAT_INDEFINITELY,
60L * 1000L);
3.创建一个触发器,立即启动.从现在开始的第10秒到第40秒重复运行.
long endTime = System.currentTimeMillis() + 40000L;
SimpleTrigger trigger = new SimpleTrigger("myTrigger",
"myGroup",
new Date(),
new Date(endTime),
SimpleTrigger.REPEAT_INDEFINITELY,
10L * 1000L);
4.创建一个触发器,在2008年5月9日,上午10点半执行,重复5次,每隔30秒一次.
java.util.Calendar cal = new java.util.GregorianCalendar(2008, cal.MARCH, 9);
cal.set(cal.HOUR, 10);
cal.set(cal.MINUTE, 30);
cal.set(cal.SECOND, 0);
cal.set(cal.MILLISECOND, 0);
Data startTime = cal.getTime()
SimpleTrigger trigger = new SimpleTrigger("myTrigger",
null,
startTime,
null,
5,
30L * 1000L);
仔细体会SimpleTrigger的例子,你会发现用这个制作执行计划会更简单方便.
