版本：.net framework 4.6.1
Quartz.net：Quartz Scheduling Framework for .NET 3.2.4
首先使用VS 创建工程->NuGet 中引用Quartz；
使用Quartz分为五步：
<1> 创建一个ISchedulerFactory，然后并且获取 Scheduler
ISchedulerFactory schedFact = new StdSchedulerFactory();
IScheduler sched = await schedFact.GetScheduler();
<2> 启动 Scheduler
await sched.Start();
<3> 创建 job 任务
IJobDetail job = JobBuilder.Create<SimpleJob>()
.WithIdentity("job1", "group1")
.Build();
<4> 创建 trigger 触发器
【1】构造一个在特定时间执行,无重复的 trigger:
// trigger builder creates simple trigger by default, actually an ITrigger is returned
ISimpleTrigger trigger = (ISimpleTrigger) TriggerBuilder.Create()
.WithIdentity("trigger1", "group1")
.StartAt(myStartTime) // some Date
.ForJob("job1", "group1") // identify job with name, group strings
.Build();
【2】构造一个在特定时间执行, 每10秒重复一次的 trigger:
trigger = TriggerBuilder.Create()
.WithIdentity("trigger3", "group1")
.StartAt(myTimeToStartFiring) // if a start time is not given (if this line were omitted), "now" is implied
.WithSimpleSchedule(x => x
.WithIntervalInSeconds(10)
.WithRepeatCount(10)) // note that 10 repeats will give a total of 11 firings
.ForJob(myJob) // identify job with handle to its JobDetail itself
.Build();
【3】构造一个在接下来的五分钟内执行一次的 trigger:
trigger=(ISimpleTrigger)TriggerBuilder.Create()
.WithIdentity("trigger5","group1")
.StartAt(DateBuilder.FutureDate(5,IntervalUnit.Minute))// use DateBuilder to create a date in the future
.ForJob(myJobKey)// identify job with its JobKey
.Build();
【4】构造一个立刻执行, 然后在 22:00 前每五分钟重复一次的 trigger:
trigger=TriggerBuilder.Create()
.WithIdentity("trigger7","group1")
.WithSimpleSchedule(x=>x
.WithIntervalInMinutes(5)
.RepeatForever())
.EndAt(DateBuilder.DateOf(22,0,0))
.Build();
<5> 使用trigger规划执行任务job
await sched.ScheduleJob(job, trigger);
待执行的任务：
public class SimpleJob : IJob
{
[MethodImpl(MethodImplOptions.Synchronized)]
public virtual Task Execute(IJobExecutionContext context)
{
LogHelper.WriteLog("start ");
Thread.Sleep(10000);
LogHelper.WriteLog("end ");
return Console.Out.WriteLineAsync($"job工作了 在{DateTime.Now}");
}
}
