Quartz中SimpleTrigger的探讨

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.
