Quartz入门 SimpleTrigger

Trigger 就是触发器的意思，用来指定什么时间开始触发，触发多少次，每隔多久触发一次
　　SimpleTrigger 可以方便的实现一系列的触发机制。

1.下一个8秒的倍数开始运行：

public class SimpleTriggerDemo {
    public static void main(String[] args) throws Exception{

        Scheduler scheduler= StdSchedulerFactory.getDefaultScheduler();

        Date startTime = DateBuilder.nextGivenSecondDate(null, 8);

        JobDetail job=JobBuilder.newJob(MailJob.class)
                .withIdentity("job1","group1")
                .usingJobData("email","憨批！")
                .build();

        SimpleTrigger trigger=(SimpleTrigger) TriggerBuilder.newTrigger()
                .withIdentity("job1","group1")
                .withSchedule(simpleSchedule().withIntervalInSeconds(1).withRepeatCount(5))
                .startAt(startTime)
                .build();

        Date ft = scheduler.scheduleJob(job, trigger);
        System.out.println("当前时间是：" + new Date().toLocaleString());
        System.out.printf("%s 这个任务会在 %s 准时开始运行，累计运行%d次，间隔时间是%d毫秒%n", job.getKey(), ft.toLocaleString(), trigger.getRepeatCount()+1, trigger.getRepeatInterval());

        scheduler.start();

        Thread.sleep(200000);
        scheduler.shutdown(true);
    }
}

 

 

 

2.10秒后运行

 Date startTime = DateBuilder.futureDate(10, DateBuilder.IntervalUnit.SECOND);

 

 

 

3.无限重复，间隔1秒
