Quartz.net 正则表达式触发器

1、创建项目

项目类型控制台应用程序,.Net Framework框架版本 4.7.2

2、引入框架

NuGet\Install-Package Quartz -Version 3.8.0

3、创建Job

自定义Job实现接口IJob,在Execute方法实现定时逻辑,

using Quartz;
using System;
using System.Threading.Tasks;

namespace QuartzConsole
{
    public class MyJob : IJob
    {
        public Task Execute(IJobExecutionContext context)
        {
            return Console.Out.WriteLineAsync($"任务开始执行了:{DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss")}");
        }
    }
}

4、创建调度器实例

使用工厂类StdSchedulerFactory创建调度器实例,

StdSchedulerFactory factory = new StdSchedulerFactory();//创建工厂实例
            var scheduler = await factory.GetScheduler();//创建调度器
            await scheduler.Start();//启动调度器

5、创建Job实例

使用Job构建器创建任务实例,

IJobDetail job = JobBuilder.Create()
                .WithIdentity("job1", "group1")
                .Build();

6、创建触发器

使用触发器构建器创建触发器实例,触发器包含简单触发器和正则表达式触发器,比如重复执行多少次这种简单的逻辑,可以使用简单触发器,比如每天21点-23点,每隔2分钟的第5秒开始执行任务,则适合使用正则表达式触发器来构建。

简单触发器:

 #region 简单触发器,每隔5秒重复执行
            ITrigger trigger = TriggerBuilder.Create()
                .WithIdentity("trigger", "group1")
                .WithSimpleSchedule(x=>x.WithInterval(TimeSpan.FromSeconds(5)).RepeatForever())
                .Build();
            #endregion

正则表达式触发器:

#region 每天21点-23点,每隔2分钟的第5秒开始执行
            ITrigger trigger = TriggerBuilder.Create()
                .WithIdentity("trigger", "group1")
                .WithCronSchedule("5 0/2 21-23 * * ?")
                .Build();
            #endregion

7、将任务和触发器安排到调度器

await scheduler.ScheduleJob(job, trigger);

            Console.ReadKey();
        }
    }
