我发现最好的方法是添加简单的 Job Listener。在我的示例中,它会在失败后重新安排工作。当然,您可以添加延迟.StartAt(DateTime.UtcNow)
public class QuartzRetryJobListner : IJobListener
{
public string Name => GetType().Name;
public async Task JobExecutionVetoed(IJobExecutionContext context, CancellationToken cancellationToken = default) => await Task.CompletedTask;
public async Task JobToBeExecuted(IJobExecutionContext context, CancellationToken cancellationToken = default) => await Task.CompletedTask;
public async Task JobWasExecuted(
IJobExecutionContext context,
JobExecutionException jobException,
CancellationToken cancellationToken = default)
{
if (jobException == null) return;
// Create and schedule new trigger
ITrigger retryTrigger = TriggerBuilder.Create()
.StartAt(DateTime.UtcNow)
.Build();
await context.Scheduler.ScheduleJob(context.JobDetail, new[] { retryTrigger }, true);
}
}
另外,我认为添加类扩展很有用
public static class QuartzExtensions
{
public static void RepeatJobAfterFall(this IScheduler scheduler, IJobDetail job)
{
scheduler.ListenerManager.AddJobListener(
new QuartzRetryJobListner(),
KeyMatcher<JobKey>.KeyEquals(job.Key));
}
}
只是为了简化使用。
_scheduler.ScheduleJob(job, trigger);
//In case of failue repeat job immediately
_scheduler.RepeatJobAfterFall(job);
