记录下Quartz的学习过程，希望可以帮助到需要的人，如果有不正确的地方还望指正。

---

环境：

开发环境：vs2019、.net core 3.1、Quartz3.2.0

官网：https://www.quartz-scheduler.net/

新建项目：

为了以后方便扩展，这里我创建的是  .NET Core Web 应用程序（MVC）

安装：

使用nuget管理器安装：搜索：Quartz

配置：

暂时用不到配置

示例：

提示：如果这里对.net core 不是很了解的，可以先了解一下再继续

注册服务：这里将调度工厂注册为单例

//注册调度器工厂
services.AddSingleton<ISchedulerFactory>(new StdSchedulerFactory());

 

修改 HomeController

注入调度工厂

        //调度器工厂private readonly ISchedulerFactory _schedulerFactory;//构造函数注入public HomeController(ISchedulerFactory schedulerFactory){//注入调度器工厂_schedulerFactory = schedulerFactory;}

增加自定义Job  ，打印当前时间

    public class HelloJob : IJob{public async Task Execute(IJobExecutionContext context){await Console.Out.WriteLineAsync($"{DateTime.Now}");}}

修改Index 为异步

        public async Task<IActionResult> Index(){return View();}

创建调度器并执行任务

 

        public async Task<IActionResult> Index(){//1、从工厂获取调度器实例IScheduler scheduler = await _schedulerFactory.GetScheduler();//2、开始调度await scheduler.Start();//3、定义作业并将其绑定到我们的HelloJob类，作业名为job1 作业组名jobGroup1IJobDetail job = JobBuilder.Create<HelloJob>().WithIdentity("job1", "jobGroup1").Build();//4、创建一个立即执行的触发器，每间隔3秒触发一次，触发器名为trigger1,触发器组名triggerGroup1ITrigger trigger = TriggerBuilder.Create().WithIdentity("trigger1", "triggerGroup1").StartNow().WithSimpleSchedule(x => x.WithIntervalInSeconds(3).RepeatForever()).Build();//5、将触发器与作业进行绑定await scheduler.ScheduleJob(job, trigger);return View();}

修改launchSettings.json文件 删除IIS相关启动配置

{"Logging": {"LogLevel": {"Default": "Information","Microsoft": "Warning","Microsoft.Hosting.Lifetime": "Information"}},"AllowedHosts": "*"
}

运行结果：

运行后，会启动一个命令窗口和一个浏览器页面，并间隔三秒打印当前时间
