quartz-scheduler - 使用 Quartz.NET 安排任务每天在特定时间运行

Question

我每天在特定时间使用 Quartz.NET 执行任务，这是我的代码:

public class TestSchedule : ISchedule
    {
        public void Run()
        {

            DateTimeOffset startTime = DateBuilder.FutureDate(2, IntervalUnit.Second);

            IJobDetail job = JobBuilder.Create<HelloJob>()
                                       .WithIdentity("job1")
                                       .Build();

            ITrigger trigger = TriggerBuilder.Create()
                                             .WithIdentity("trigger1")
                                             .StartAt(startTime)
                                             .WithDailyTimeIntervalSchedule(x => x.OnEveryDay().StartingDailyAt(new TimeOfDay(7, 0)).WithRepeatCount(0))
                                             .Build();

            ISchedulerFactory sf = new StdSchedulerFactory();
            IScheduler sc = sf.GetScheduler();
            sc.ScheduleJob(job, trigger);

            sc.Start();
        }
    }

我的代码正在运行，但问题是它只能运行一次(似乎是因为 WithRepeatCount(0))
现在，怎么能说每天七点钟运行呢？
PS:我不想使用 CronTrigger要做到这一点。

Answer 1

DailyTimeIntervalTriggerImpl仅支持重复计数 .

This trigger also supports "repeatCount" feature to end the trigger fire time after a certain number of count is reached. Just as the SimpleTrigger, setting repeatCount=0 means trigger will fire once only! Setting any positive count then the trigger will repeat count + 1 times. Unlike SimpleTrigger, the default value of repeatCount of this trigger is set to REPEAT_INDEFINITELY instead of 0 though.

Cron 表达式很漂亮，还有很多 tools这可以帮助您实现您正在寻找的目标。

另一种选择是使用 SimpleTriggerImpl并每 24 小时设置一次间隔:

ITrigger trigger = TriggerBuilder.Create()
        .WithIdentity("trigger1")
        .StartAt(startTime)
        .WithSimpleSchedule(x => x.RepeatForever().WithIntervalInHours(24))
        .Build();
