Quartz,启动不立即执行问题

我的Quartz 是2.2版本，

在java程序中写了两个加入计划方法

////  添加简单计划任务 author:iresearch.com.cn -- jackical
 	public static void AddSimplejob(String jobName,String strTrigger,int id,int hour,int minute,Date DateStart) throws SchedulerException{

		Scheduler sched=sf.getScheduler();

		Calendar calendar=GregorianCalendar.getInstance();
		calendar.setTime(DateStart);
		int intYear= calendar.get(Calendar.YEAR);
		int intMonth=calendar.get(Calendar.MONTH)+1;
		int intDay=calendar.get(Calendar.DAY_OF_MONTH);

		Date runDate=DateBuilder.dateOf(hour, minute, 0,intDay,intMonth,intYear);   //////  设置执行的时间

		JobDetail jobDetail=JobBuilder.newJob(DoJob.class)
				.withIdentity(jobName,JOB_GROUP_NAME)
				.usingJobData("id",id)
				.build();

		SimpleTrigger trigger=(SimpleTrigger)TriggerBuilder
				.newTrigger()
				.withIdentity(strTrigger,TRIGGER_GROUP_NAME)
				.startAt(runDate)
				.withSchedule(SimpleScheduleBuilder.simpleSchedule()
						.withIntervalInMinutes(3)
						.withRepeatCount(0)
						)
				.build();

		/*
		 * 				.withSchedule(SimpleScheduleBuilder.simpleSchedule()
						.withIntervalInSeconds(10)
						.withRepeatCount(0)
						)
		 * */

		sched.scheduleJob(jobDetail,trigger);
		sched.start();
	}

	/////  添加定时任务 author:iresearch.com.cn -- jackical
 	public static void AddCronJob(String jobName,String strTrigger,int id,String strExp,Date DateStart,Date DateEnd) throws SchedulerException, ParseException{

		Scheduler sched=sf.getScheduler();

		JobDetail jobDetail=JobBuilder.newJob(DoJob.class)
				.withIdentity(jobName,JOB_GROUP_NAME)
				.usingJobData("id",id)
				.build();

		Trigger trigger=(CronTrigger)TriggerBuilder
				.newTrigger()
				.withIdentity(strTrigger,TRIGGER_GROUP_NAME)
				.startAt(DateStart)
				.endAt(DateEnd)
				.withSchedule(CronScheduleBuilder.cronSchedule(strExp)
						.withMisfireHandlingInstructionDoNothing()
						)
				.build();

		sched.scheduleJob(jobDetail,trigger);
		sched.start();

	}

　　

发现这个使用simpleTrigger 的没有参数设置第一次启动时不执行 ....只有CromTrigger 有个参数可以设置第一次添加不执行计划 “withMisfireHandlingInstructionDoNothing()”

所以我的第一个方法就废了，但第二个方法一样可以用.....
