Quartz.NET 任务调度框架的demo实例

发布日期: 2021-12-09

1、新建项目

简单实例，新建一个控制台程序

2、Nuget安装Quartz

3、编写代码

using Quartz;
using Quartz.Impl;
using Quartz.Logging;
using System;
using System.IO;
using System.Threading.Tasks;
namespace QuartzDotNetDemo
{
    class Program
    {
        static async Task Main(string[] args)
        {
            LogProvider.SetCurrentLogProvider(new ConsoleLogProvider());
            // 获取调度程序的实例
            // 创建调度器工厂
            StdSchedulerFactory factory = new StdSchedulerFactory();
            // 创建调度器
            IScheduler scheduler = await factory.GetScheduler();
            // 启动
            await scheduler.Start();
            // 创建一个任务
            IJobDetail job = JobBuilder.Create<HelloJob>().WithIdentity("job1", "group1").Build();
            // 创建一个触发器
            ITrigger trigger = TriggerBuilder.Create().WithIdentity("trigger1", "group1").StartNow().WithSimpleSchedule(x => x.WithIntervalInSeconds(10) // 间隔10秒执行一次
                .RepeatForever()).Build();
            // 将任务与出发器添加到调度器中
            await scheduler.ScheduleJob(job, trigger);
            // 延迟60秒后启动
            await Task.Delay(TimeSpan.FromSeconds(60));
            // 关闭
            await scheduler.Shutdown();
            Console.WriteLine("Press any key to close the application");
            Console.ReadKey();
        }
    }

                    }
                    return true;
                };
            }
            public IDisposable OpenMappedContext(string key, object value, bool destructure = false)

                throw new NotImplementedException();
            }
            public IDisposable OpenNestedContext(string message)
            {
