如何在Quartz.NET 2.0中将Cron misfire指令FireOnceNow与AdoJobStore一起使用? [英] How to use cron misfire-instruction FireOnceNow with AdoJobStore in Quartz.NET 2.0?
问题描述
我在 quartz.net-2.0 通过AdoJobStore设置并使用XMLSchedulingDataProcessorPlugin.
I am using a cron trigger with misfire-instruction set to FireOnceNow in quartz.net-2.0 set up with AdoJobStore and using XMLSchedulingDataProcessorPlugin.
cron-expression已设置，因此作业将每1分钟触发一次:0 0/1 * * * ?.
cron-expression is set so the job will trigger every 1 minute: 0 0/1 * * * ?.
作业计划程序设置为从Global.asax.cs开始.
The job scheduler is set to start in Global.asax.cs.
预期的行为:如果在应触发作业时服务器已停止，但在下一次触发之前已重新启动，则应立即触发一次.
Expected behaviour: If the server is stopped when a job should trigger but it is restarted before the next trigger then it should trigger once immediately.
示例:
第一个作业在 00:01:00 触发.
我在 00:02:00 可以触发之前就停止了服务器，但是应该在它应该触发后的几秒钟内启动它，例如 00:02:10 .
I stop the server before 00:02:00 can trigger but start it a few seconds after it should, let's say 00:02:10.
当我重新启动服务器(在 00:02:10 时)时，我希望在 00:02:00 处未触发的作业将触发一次然后恢复正常触发行为将继续.
When I restart the server (at 00:02:10) I would expect for the job that misfired at 00:02:00 would fire once and then normal trigger behavior would continue.
真正发生的事情是什么都不会触发.它只是从 00:03:00 继续触发.
What really happens is that nothing triggers. It just continues triggering from 00:03:00.
有什么想法可以使它按预期工作吗?
Any ideas what I have to do to make it work as expected?

推荐答案
问题是，quartz_jobs.xml的每次自动处理都会覆盖失火操作正常运行所需的触发数据.
The problem was that the trigger data required for misfire action to work properly was overridden on each automatic processing of quartz_jobs.xml.
因此，将overwrite-existing-data设置为false是触发失败后触发器起作用的必要条件:
So setting overwrite-existing-data to false was required for the trigger to work after misfire:
<processing-directives>
<overwrite-existing-data>false</overwrite-existing-data>
<ignore-duplicates>true</ignore-duplicates>
</processing-directives>
