本文介绍了在作业完成完全执行后调用函数的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我们正在使用Quartz.Net在Windows服务中按计划触发作业。

我遇到从Start DateTimeEnd DateTime每隔5 minutes必须触发作业的情况。

作业完成后,我们需要计算Next Start DateTimeNext End DateTime并保存到数据库-

为此,我尝试重写JobListener,它有一个方法:JobWasExecuted

public class xPTJobListener : JobListenerSupport
{
    public override string Name { get { return "xPTJobListener"; } }

    public override void JobWasExecuted(IJobExecutionContext context, JobExecutionException jobException)
    {

        var dataMap = context.MergedJobDataMap;
        var schedule = (MyDTO)dataMap["Schedule"];

        using (var logger = new xPTLogger())
        {
            logger.LogMessage(MessageType.Information, string.Format("Inside JobWasExecuted() - [{0}] - ", schedule.Id));
        }

        base.JobWasExecuted(context, jobException);
    }
}

TriggerListener中的TriggerComplete

public class xPTTriggerListener : TriggerListenerSupport
{
    public override string Name { get { return "xPTTriggerListener"; } }

    public override void TriggerComplete(ITrigger trigger, IJobExecutionContext context, SchedulerInstruction triggerInstructionCode)
    {

        var dataMap = context.MergedJobDataMap;
        var schedule = (MyDTO)dataMap["Schedule"];

        using (var logger = new xPTLogger())
        {
            logger.LogMessage(MessageType.Information, string.Format("Inside Trigger Complete - [{0}] - ", schedule.Id));
        }


        base.TriggerComplete(trigger, context, triggerInstructionCode);

    }
}

但上述方法的问题在于,每次调用作业时都会执行它们。

因此,如果我有一个作业,该作业从12:01 AM运行并每隔5秒结束12:02 AM,则这两个方法都被调用12 times

我需要的是在一个作业迭代结束后只调用一次方法-(在作业执行12次之后)?

如何在Quartz中执行此操作?

创建触发器

public static ITrigger GenerateTrigger(RouteMonitorScheduleDTO routeSchedule, double fGmtOffset, xPTLogger logger)
{
    ITrigger trigger = null;

    switch (routeSchedule.ScheduleInfo.PeriodType)
    {
        case PeriodTypeEnum.Once:
            trigger = TriggerBuilder.Create()
                        .WithIdentity(string.Format("trigger_{0}", routeSchedule.RouteScheduleId), DefaultGroup)
                        .StartAt(routeSchedule.DepartureDateTime)
                        .WithSimpleSchedule(s => s.WithIntervalInMinutes(5))
                        .EndAt(routeSchedule.ArrivalDateTime.AddMinutes(5))
                        .Build();
            break;
        case PeriodTypeEnum.Daily:
        case PeriodTypeEnum.WeekDays:
        case PeriodTypeEnum.Weekly:
        case PeriodTypeEnum.Monthly:
            var schedule = routeSchedule.ScheduleInfo;        
            var cronExpresion = xPTCronBuilder.GenerateCronExpression(
                                    schedule.PeriodType,                         
                                    schedule.ScheduleStringValue, 
                                    fGmtOffset,             
                                    routeSchedule.DepartureDateTime,
                                    routeSchedule.ArrivalDateTime.AddMinutes(5), 5);
            trigger = TriggerBuilder.Create()
                        .WithIdentity(string.Format("trigger_{0}", routeSchedule.RouteScheduleId), DefaultGroup)
                        .WithCronSchedule(cronExpresion)
                        .Build();
            break;
    }

    return trigger;
}

编辑带Cron的触发器:

trigger = TriggerBuilder.Create()
.WithIdentity(string.Format("trigger_{0}", 1), "Group1")
.WithCronSchedule("0 0-45/5 7-7 ? * TUE,WED *").Build();

从上面的cron表达式可以看到,它将从7 AM to 7:45 AM5 minutesTuesdayWednesday运行。

因此,第一次迭代是在Tuesday,下一次是7 AM to 7:45,在Wednesday。我需要在每次迭代完成后调用一个函数。

假设当为7:45 AM on Tuesday触发最后一个触发器时,我需要调用该函数。

推荐答案

如果我正确理解您的问题,您可以通过以下方式使用ITriggerListener完成此操作:

public class xPTTriggerListener : TriggerListenerSupport {
    public override string Name
    {
        get { return "xPTTriggerListener"; }
    }

    public override void TriggerComplete(ITrigger trigger, IJobExecutionContext context, SchedulerInstruction triggerInstructionCode) {
        if (triggerInstructionCode == SchedulerInstruction.DeleteTrigger) {
            // means this trigger won't be fired again - now recalculate your dates in database
        }
        base.TriggerComplete(trigger, context, triggerInstructionCode);
    }
}
