创建简易控制台定时任务

• 创建winform的可以看：https://blog.csdn.net/wayhb/article/details/134279205

步骤

1. 创建控制台程序

• 使用vs2019
• 新建项目，控制台程序，使用.net4.7.2
• 项目右键（管理NuGet程序包），搜索Quartz，安装
  

2. 使用Quartz.Net官网示例运行程序

• 打开官网https://www.quartz-scheduler.net/documentation/quartz-3.x/quick-start.html#trying-out-the-application，在程序入库Program.cs粘贴官网示例

//出现错误右键修复，自动添加包
using Quartz;
using Quartz.Impl;
using Quartz.Logging;
using System;
using System.Threading.Tasks;namespace ConsoleSkWork
{class Program{private static async Task Main(string[] args){LogProvider.SetCurrentLogProvider(new ConsoleLogProvider());// Grab the Scheduler instance from the FactoryStdSchedulerFactory factory = new StdSchedulerFactory();IScheduler scheduler = await factory.GetScheduler();// and start it offawait scheduler.Start();// define the job and tie it to our HelloJob classIJobDetail job = JobBuilder.Create<HelloJob>().WithIdentity("job1", "group1").Build();// Trigger the job to run now, and then repeat every 10 secondsITrigger trigger = TriggerBuilder.Create().WithIdentity("trigger1", "group1").StartNow().WithSimpleSchedule(x => x.WithIntervalInSeconds(10).RepeatForever()).Build();// Tell Quartz to schedule the job using our triggerawait scheduler.ScheduleJob(job, trigger);// some sleep to show what's happeningawait Task.Delay(TimeSpan.FromSeconds(60));// and last shut down the scheduler when you are ready to close your programawait scheduler.Shutdown();Console.WriteLine("Press any key to close the application");Console.ReadKey();}// simple log provider to get something to the console//https://www.quartz-scheduler.net/documentation/quartz-3.x/quick-start.html#trying-out-the-applicationprivate class ConsoleLogProvider : ILogProvider{public Logger GetLogger(string name){return (level, func, exception, parameters) =>{if (level >= LogLevel.Info && func != null){Console.WriteLine("[" + DateTime.Now.ToLongTimeString() + "] [" + level + "] " + func(), parameters);}return true;};}public IDisposable OpenNestedContext(string message){throw new NotImplementedException();}public IDisposable OpenMappedContext(string key, object value, bool destructure = false){throw new NotImplementedException();}}}public class HelloJob : IJob{public async Task Execute(IJobExecutionContext context){await Console.Out.WriteLineAsync("Greetings from HelloJob!");}}
}

• 运行控制台程序
  
  说明：
  info是日志插件输出的
  hellojob就是任务触发的

4. 添加触发监听器

• 触发监听器是用于监听触发器的
• 添加触发监听器可以在任务执行前后执行其他动作，例如输出下一次该任务执行时间
• 触发监听器官网解释：https://www.quartz-scheduler.net/documentation/quartz-3.x/tutorial/trigger-and-job-listeners.html
• 继承触发监听器接口有4个方法需要实现

//触发器执行前
public async Task TriggerFired(ITrigger trigger, IJobExecutionContext context, CancellationToken cancellationToken = default)
{}
// 判断作业是否继续（true继续，false本次不触发）
public async Task<bool> VetoJobExecution(ITrigger trigger, IJobExecutionContext context, CancellationToken cancellationToken = default)
{}
//  触发完成
public async Task TriggerComplete(ITrigger trigger, IJobExecutionContext context, SchedulerInstruction triggerInstructionCode, CancellationToken cancellationToken = default)
{}
// 触发失败
public async Task TriggerMisfired(ITrigger trigger, CancellationToken cancellationToken = default)
{}

• 主程序中添加触发监听器

           // 将trigger监听器注册到调度器scheduler.ListenerManager.AddTriggerListener(new CustomTriggerListener());

完整程序

• Program.cs

using System;
using System.Threading.Tasks;using Quartz;
using Quartz.Impl;
using Quartz.Logging;namespace ConsoleApp1
{public class Program{private static async Task Main(string[] args){LogProvider.SetCurrentLogProvider(new ConsoleLogProvider());// Grab the Scheduler instance from the FactoryStdSchedulerFactory factory = new StdSchedulerFactory();IScheduler scheduler = await factory.GetScheduler();// and start it offawait scheduler.Start();// define the job and tie it to our HelloJob classIJobDetail job = JobBuilder.Create<HelloJob>().WithIdentity("job1", "group1").Build();// Trigger the job to run now, and then repeat every 10 secondsITrigger trigger = TriggerBuilder.Create().WithIdentity("trigger1", "group1").StartNow().WithSimpleSchedule(x => x.WithIntervalInSeconds(10).RepeatForever()).Build();// 将trigger监听器注册到调度器scheduler.ListenerManager.AddTriggerListener(new CustomTriggerListener());// Tell Quartz to schedule the job using our triggerawait scheduler.ScheduleJob(job, trigger);// some sleep to show what's happeningawait Task.Delay(TimeSpan.FromSeconds(60));// and last shut down the scheduler when you are ready to close your programawait scheduler.Shutdown();Console.WriteLine("Press any key to close the application");Console.ReadKey();}// simple log provider to get something to the consoleprivate class ConsoleLogProvider : ILogProvider{public Logger GetLogger(string name){return (level, func, exception, parameters) =>{if (level >= LogLevel.Info && func != null){Console.WriteLine("[" + DateTime.Now.ToLongTimeString() + "] [" + level + "] " + func(), parameters);}return true;};}public IDisposable OpenNestedContext(string message){throw new NotImplementedException();}public IDisposable OpenMappedContext(string key, object value, bool destructure = false){throw new NotImplementedException();}}}public class HelloJob : IJob{public async Task Execute(IJobExecutionContext context){//获取当前时间DateTime currentDateTime = DateTime.UtcNow;await Console.Out.WriteLineAsync("当前日期和时间：" + currentDateTime.AddHours(8));}}
}

• CustomTriggerListener.cs

using Quartz;
using System;
using System.Threading;
using System.Threading.Tasks;namespace ConsoleApp1
{//继承监听器接口public class CustomTriggerListener : ITriggerListener{public string Name => "CustomTriggerListener";//触发器执行前public async Task TriggerFired(ITrigger trigger, IJobExecutionContext context, CancellationToken cancellationToken = default){Console.WriteLine("【*********************************************】");Console.WriteLine($"【{Name}】---【TriggerFired】-【触发】");await Task.CompletedTask;}// 判断作业是否继续（true继续，false本次不触发）public async Task<bool> VetoJobExecution(ITrigger trigger, IJobExecutionContext context, CancellationToken cancellationToken = default){Console.WriteLine($"【{Name}】---【VetoJobExecution】-【判断作业是否继续】-{true}");return await Task.FromResult(cancellationToken.IsCancellationRequested);}//  触发完成public async Task TriggerComplete(ITrigger trigger, IJobExecutionContext context, SchedulerInstruction triggerInstructionCode, CancellationToken cancellationToken = default){Console.WriteLine($"【{Name}】---【TriggerComplete】-【触发完成】");//获取下次执行日期时间UTC，将UTC时间转换成北京时间DateTimeOffset dd = (DateTimeOffset)trigger.GetNextFireTimeUtc();Console.WriteLine("【下次执行时间：】"+dd.DateTime.AddHours(8));await Task.CompletedTask;}// 触发失败public async Task TriggerMisfired(ITrigger trigger, CancellationToken cancellationToken = default){Console.WriteLine($"【{Name}】---【TriggerMisfired】【触发作业】");await Task.CompletedTask;}}}
