讓我們繼續(xù)用第一個例子中StringTest.
1.來寫一個每隔10秒啟動一次任務(wù)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();
// 系統(tǒng)當(dāng)前時間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.創(chuàng)建一個觸發(fā)器,立即啟動,每隔60秒,啟動一次.
SimpleTrigger trigger = new SimpleTrigger("myTrigger",
null,
new Date(),
null,
SimpleTrigger.REPEAT_INDEFINITELY,
60L * 1000L);
3.創(chuàng)建一個觸發(fā)器,立即啟動.從現(xiàn)在開始的第10秒到第40秒重復(fù)運行.
long endTime = System.currentTimeMillis() + 40000L;
SimpleTrigger trigger = new SimpleTrigger("myTrigger",
"myGroup",
new Date(),
new Date(endTime),
SimpleTrigger.REPEAT_INDEFINITELY,
10L * 1000L);
4.創(chuàng)建一個觸發(fā)器,在2008年5月9日,上午10點半執(zhí)行,重復(fù)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);
仔細(xì)體會SimpleTrigger的例子,你會發(fā)現(xiàn)用這個制作執(zhí)行計劃會更簡單方便.
