创建简易控制台定时任务
步骤
- 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
- 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
cs
复制代码
//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 Factory
StdSchedulerFactory factory = new StdSchedulerFactory();
IScheduler scheduler = await factory.GetScheduler();
// and start it off
await scheduler.Start();
// define the job and tie it to our HelloJob class
IJobDetail job = JobBuilder.Create<HelloJob>()
.WithIdentity("job1", "group1")
.Build();
// Trigger the job to run now, and then repeat every 10 seconds
ITrigger trigger = TriggerBuilder.Create()
.WithIdentity("trigger1", "group1")
.StartNow()
.WithSimpleSchedule(x => x
.WithIntervalInSeconds(10)
.RepeatForever())
.Build();
// Tell Quartz to schedule the job using our trigger
await scheduler.ScheduleJob(job, trigger);
// some sleep to show what's happening
await Task.Delay(TimeSpan.FromSeconds(60));
// and last shut down the scheduler when you are ready to close your program
await 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-application
private 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
- 添加触发监听器
cs
复制代码
//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)
{}
cs
复制代码
// 将trigger监听器注册到调度器
scheduler.ListenerManager.AddTriggerListener(new CustomTriggerListener());
