初探Quartz，运行代码不报错，但任务没有执行?报错

public void test1() throws SchedulerException {
JobDetail jobDetail = new JobDetail("job1", "jobGroup1", SimpleJob.class);
SimpleTrigger trigger = new SimpleTrigger("trigger1", "triggerGroup1");
trigger.setStartTime(new Date());
trigger.setRepeatInterval(2000);
trigger.setRepeatCount(5);
trigger.setJobName("job1");
trigger.setJobGroup("jobGroup1");

SchedulerFactory factory = new StdSchedulerFactory();
Scheduler scheduler = factory.getScheduler();
scheduler.addJob(jobDetail, true);
scheduler.scheduleJob(trigger);
scheduler.start();
}
