Quartz.NET学习系列(二)--- 简单触发器

        Quartz.NET的触发器比较多，但是常用的有两个分别是SimpleTrigger和CronTrigger，本篇学习下SimpleTrigger

        SimpleTrigger 的创建方式如下：

ISimpleTrigger trigger = (ISimpleTrigger) TriggerBuilder.Create()
                                           .WithIdentity("trigger1", "group1")
                                           .StartAt(startTime)
                                           .Build();

ISimpleTrigger有较多方法，常用的方法有 StartAt(开始时间)  WithSimpleSchedule(执行间隔次数等设置) ForJob（特定的任务触发器）

以下是应用的代码：

        public class SimpleJob : IJob
	{
		private ILog log = LogManager.GetLogger(typeof(SimpleJob));

		public virtual void Execute(IJobExecutionContext context)
		{
			JobKey jobKey = context.JobDetail.Key;
                        log.InfoFormat("任务: {0} 执行时间：{1}", jobKey, DateTime.Now.ToString());
		}
	}

    public class SimpleTriggerExample 
    {
        public static void Run()
        {
            ILog log = LogManager.GetLogger(typeof (SimpleTriggerExample));

            ISchedulerFactory sf = new StdSchedulerFactory();
            IScheduler sched = sf.GetScheduler();

            DateTimeOffset startTime = DateBuilder.NextGivenSecondDate(null, 5);

            //job1在5秒之后运行
            IJobDetail job = JobBuilder.Create<SimpleJob>()
                .WithIdentity("job1", "group1")
                .Build();

            ISimpleTrigger trigger = (ISimpleTrigger) TriggerBuilder.Create()
                                                          .WithIdentity("trigger1", "group1")
                                                          .StartAt(startTime)
                                                          .Build();

            DateTimeOffset? ft = sched.ScheduleJob(job, trigger);
            log.Info(job.Key +
                     " 开始时间: " + ft +
                     " 执行次数: " + trigger.RepeatCount +
                     " 执行间隔" + trigger.RepeatInterval.TotalSeconds);

            // job2 每1秒执行一次，共执行6次（其中开始1此，重复5次）
            job = JobBuilder.Create<SimpleJob>()
                .WithIdentity("job2", "group1")
                .Build();

            trigger = (ISimpleTrigger) TriggerBuilder.Create()
                                           .WithIdentity("trigger2", "group1")
                                           .StartAt(startTime)
                                           .WithSimpleSchedule(x => x.WithIntervalInSeconds(1).WithRepeatCount(5))
                                           .Build();

            ft = sched.ScheduleJob(job, trigger);
            log.Info(job.Key +
                     " 开始时间: " + ft +
                     " 执行次数: " + trigger.RepeatCount +
                     " 执行间隔" + trigger.RepeatInterval.TotalSeconds);

            

            //job2被替换 原来照常执行 组别不一样
            trigger = (ISimpleTrigger) TriggerBuilder.Create()
                                           .WithIdentity("trigger2", "group2")
                                           .StartAt(startTime)
                                           .WithSimpleSchedule(x => x.WithIntervalInSeconds(1).WithRepeatCount(2))
                                           .ForJob(job)
                                           .Build();

            ft = sched.ScheduleJob(trigger);
            log.Info(job.Key +
                     " 开始时间: " + ft +
                     " 执行次数: " + trigger.RepeatCount +
                     " 执行间隔" + trigger.RepeatInterval.TotalSeconds);

            // job3 5秒后执行
            job = JobBuilder.Create<SimpleJob>()
                .WithIdentity("job3", "group1")
                .Build();

            trigger = (ISimpleTrigger) TriggerBuilder.Create()
                                           .WithIdentity("trigger3", "group1")
                                           .StartAt(DateBuilder.FutureDate(5, IntervalUnit.Second))
                                           .Build();

            ft = sched.ScheduleJob(job, trigger);
            log.Info(job.Key +
                     " 开始时间: " + ft +
                     " 执行次数: " + trigger.RepeatCount +
                     " 执行间隔" + trigger.RepeatInterval.TotalSeconds);

            sched.Start();

            log.Info("------- 开始计划 -----------------");

            job = JobBuilder.Create<SimpleJob>()
                .WithIdentity("job5", "group1")
                .Build();

            ISimpleTrigger trigger1 = (ISimpleTrigger)TriggerBuilder.Create()
                                           .WithIdentity("trigger5", "group1")
                                           .StartAt(startTime)
                                           .WithSimpleSchedule(x => x.WithIntervalInSeconds(1).WithRepeatCount(2))
                                           .Build();

            log.Info(job.Key +

            sched.AddJob(job, true);

            log.Info("job6触发...");
            sched.TriggerJob(new JobKey("job6", "group1"));

代码均已经注释，以上是一些简单触发器的应用场景，主要是针对 持续时间的配置
