c# - 创建一个暂停的触发器

Question

是否可以在暂停状态下向调度程序添加触发器？我发现如果我不指定开始时间，它将立即开始。

除了立即调用 scheduler.PauseJob 是否可以通过其他方式完成？

var trigger = TriggerBuilder.Create()
    .ForJob(job)
    .WithSimpleSchedule(schedule => schedule.WithIntervalInMinutes(1).RepeatForever())
    .Build();

scheduler.ScheduleJob(job, trigger);

// Pause job immediately
scheduler.PauseJob(job.Key);

Answer 1

实际上可以使用触发器组来做到这一点。您只需要暂停一个特定的触发器组，然后创建一个触发器属于该组的作业。

// pauses the group, if it isn't already
scheduler.PauseTriggers(GroupMatcher<TriggerKey>.GroupEquals("PausedGroup"));

var job = JobBuilder.Create<MyJob>().WithIdentity(jobName).Build();

var trigger = TriggerBuilder.Create()
    .ForJob(job)
    .WithIdentity(Guid.NewGuid().ToString(), "PausedGroup")
    .WithSimpleSchedule(schedule => schedule.WithIntervalInMinutes(1).RepeatForever())
    .Build();

scheduler.ScheduleJob(job, trigger);

然后要恢复工作，用不同的组重新安排每个触发器:

foreach (var oldTrigger in scheduler.GetTriggers(new JobKey(jobName)))
{
    // clone the old trigger with new group name
    var newTrigger = oldTrigger.GetTriggerBuilder()
        .WithIdentity(oldTrigger.Key.Name) // uses default trigger group name
        .Build();

    // not a typo, the method to reschedule a trigger is called "RescheduleJob" for some reason
    scheduler.RescheduleJob(oldTrigger.Key, newTrigger);
}
