基于Quartz和Topshelf创建简单的任务调度

Quartz + Topshelf创建Windows Service

源码地址:https://github.com/qyjwork/QuartzDemo

一 Quartz

Quartz是一个完全由java编写的开源的,轻量级的作业调度框架,Quartz.Net是Quartz的.Net实现,最新版本为3.0.6

官网：http://www.quartz-scheduler.net/

源码：https://github.com/quartznet/quartznet

示例：https://www.quartz-scheduler.net/documentation/quartz-3.x/quick-start.html

二 Topshelf

Topshelf是构建Windows Service的一种方式,与传统的Win Service 相比较,更新简单,轻量,易调试

官网:http://topshelf-project.com/

基于Quartz和Topshelf创建简单的任务调度

1. 创建一个控制台项目
2. 通过nuget安装以下Quartz依赖
   Quartz , CrystalQuartz.Owin //监控页面做准备
3. 安装Topshelf需要的依赖
   Topshelf, Microsoft.Owin.Hosting,Microsoft.Owin,Owin等
4. 新建任务类

namespace QuartzDemo
{
    //实现JJob接口  3.0之后该接口方法为async模式 
    public class TestJob1 : IJob
    {
        public async Task Execute(IJobExecutionContext context)
        {
            await Task.Factory.StartNew(() =>
            {
                var data = context.JobDetail.JobDataMap;

                Console.WriteLine($"{DateTime.Now.ToString("yyyy-MM-dd HH:MM:ss")} TestJob1");
                //以下输出可以输出任务的相信信息,包括名称等
                //Console.WriteLine($"{DateTime.Now.ToString("yyyy-MM-dd HH:MM:ss")} {Environment.NewLine}TestJob1 Name: {data.Get("name")} TestJob1 Description:{context.JobDetail.Description} {Environment.NewLine}Trigger: Name:{context.Trigger.Key.Name} Description:{context.Trigger.Description}");
            });
        }

    }
}

1. 新建QuartzWrapper类型

namespace QuartzDemo
{
    public class QuartzWrapper
    {
        private IScheduler scheduler = null;
        private IDisposable webApp = null;
        private async Task InitJob()
        {
            //定义任务一
            IJobDetail jobDetail1 = JobBuilder.Create<TestJob1>().WithIdentity("job1", "group1").UsingJobData("name", "job1").WithDescription("this is job1").Build();
            ITrigger trigger1 = TriggerBuilder.Create().WithIdentity("trigger1", "group1").WithDescription("this  is  job1's Trigger").WithSimpleSchedule(it => it.WithIntervalInSeconds(3).RepeatForever()).Build();

            //定义任务二
            IJobDetail jobDetail2 = JobBuilder.Create<TestJob2>().WithIdentity("job2", "group1").Build();
            ITrigger trigger2 = TriggerBuilder.Create().WithIdentity("trigger2", "group1").WithSimpleSchedule(it => it.WithIntervalInSeconds(5).RepeatForever()).Build();

            //初始化调度器
            scheduler = new StdSchedulerFactory().GetScheduler().GetAwaiter().GetResult();

            //将任务添加到调度器
            await scheduler.ScheduleJob(jobDetail1, trigger1);
            await scheduler.ScheduleJob(jobDetail2, trigger2);
        }

        public async Task Start()
        {
            //初始化任务信息
            await this.InitJob();

            //定义监控页面
            Action<IAppBuilder> startup = app => app.UseCrystalQuartz(() => { return scheduler; });
            string listeningUrl = "http://127.0.0.1:9008/";
            webApp = WebApp.Start(listeningUrl, startup);
            Console.WriteLine("Server is started");
            Console.WriteLine("URL:" + listeningUrl);
            Console.WriteLine("Starting scheduler...");
            await scheduler.Start();
            Console.WriteLine("scheduler is Started");
        }
        public void Stop()
        {
            this.scheduler.Clear();
            this.scheduler.Shutdown(false);
        }
    }
}

1. 修改main方法如下

static void Main(string[] args)
        {
            HostFactory.New(x =>
            {
                x.StartAutomatically();
                x.UseAssemblyInfoForServiceInfo();
                x.Service<QuartzWrapper>(s => {
                    s.ConstructUsing(srv => new QuartzWrapper());
                    s.WhenStarted(async job => await job.Start());
                    s.WhenStopped(job => job.Stop());
                });
                x.SetServiceName("Quartz任务");
                x.SetDisplayName("Quartz任务");
                x.SetDescription("Quartz任务");
                x.EnableServiceRecovery(sr =>
                {
                    sr.RestartService(1);
                    sr.RestartService(2);
                });
            }).Run();
        }

1 此时运行程序 即可看到任务执行情况

打开浏览器输入代码中配置的地址:http://127.0.0.1:9008/ 可看到任务执行情况,如下图,我们可以清楚地看到任务的分组,执行时间,任务执行次数等

PS:如出现"the server factory could not be located for the given input"的错误,只需要添加Microsoft.Owin.Host.HttpListener依赖即可
