Quartz.NET管理周期性任务

Quartz.NET是一个开源的作业调度框架，非常适合在平时的工作中，定时轮询数据库同步，定时邮件通知，定时处理数据等。 Quartz.NET允许开发人员根据时间间隔（或天）来调度作业。它实现了作业和触发器的多对多关系，还能把多个作业与不同的触发器关联。整合了 Quartz.NET的应用程序可以重用来自不同事件的作业，还可以为一个事件组合多个作业。

1. 新建一个控制台项目QuartzDemo，引用Topshelf、Log4net和Quartz。

Install-Package Topshelf
Install-Package Topshelf.Log4Net
Install-Package Quartz

2. 修改相关文件。
Program.cs：

using System;
using System.IO;
using log4net;
using log4net.Config;
using Quartz;
using Quartz.Impl;
using Topshelf;

namespace QuartzDemo
{
class Program
{
public static void Main()
{
var logCfg = new FileInfo(AppDomain.CurrentDomain.BaseDirectory + "log4net.xml");
XmlConfigurator.ConfigureAndWatch(logCfg);

HostFactory.Run(x =>
{
x.UseLog4Net();
x.Service<QuartzService>();
x.RunAsLocalSystem();

x.SetDescription("Quartz Service");
x.SetDisplayName("QuartzService");
x.SetServiceName("QuartzService");

x.EnablePauseAndContinue();
});
}
}

public sealed class QuartzService : ServiceControl, ServiceSuspend
{
private readonly IScheduler scheduler;

public QuartzService()
{
scheduler = StdSchedulerFactory.GetDefaultScheduler();
}

public bool Start(HostControl hostControl)
{
scheduler.Start();
return true;
}

public bool Stop(HostControl hostControl)
{
scheduler.Shutdown(false);
return true;
}

public bool Continue(HostControl hostControl)
{
scheduler.ResumeAll();
return true;
}

public bool Pause(HostControl hostControl)
{
scheduler.PauseAll();
return true;
}
}

public sealed class TestJob : IJob
{
private readonly ILog _logger = LogManager.GetLogger(typeof(TestJob));

public void Execute(IJobExecutionContext context)
{
_logger.InfoFormat("TestJob测试");
}
}
}

log4net.xml：

<?xml version="1.0" encoding="utf-8" ?>
<log4net>

<root>

<level value="all" />
<appender-ref ref="ColoredConsoleAppender"/>
<appender-ref ref="RollingLogFileAppender"/>
</root>
</log4net>

quartz.config：

# You can configure your scheduler in either <quartz> configuration section
# or in quartz properties file
# Configuration section has precedence

quartz.scheduler.instanceName = QuartzTest

# configure thread pool info
quartz.threadPool.type = Quartz.Simpl.SimpleThreadPool, Quartz
quartz.threadPool.threadCount = 10
quartz.threadPool.threadPriority = Normal

# job initialization plugin handles our xml reading, without it defaults are used
quartz.plugin.xml.type = Quartz.Plugin.Xml.XMLSchedulingDataProcessorPlugin, Quartz
quartz.plugin.xml.fileNames = ~/quartz_jobs.xml

# export this server to remoting context
#quartz.scheduler.exporter.type = Quartz.Simpl.RemotingSchedulerExporter, Quartz
#quartz.scheduler.exporter.port = 555
#quartz.scheduler.exporter.bindName = QuartzScheduler
#quartz.scheduler.exporter.channelType = tcp
#quartz.scheduler.exporter.channelName = httpQuartz

quartz_jobs.xml：

<?xml version="1.0" encoding="UTF-8"?>

<job-scheduling-data xmlns="http://quartznet.sourceforge.net/JobSchedulingData" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.0">

<schedule>

</schedule>

</job-scheduling-data>

3. 执行，在控制台和日志文件中每3秒钟显示一条测试信息：



注意，log4net.xml、quartz.config、quartz_jobs.xml，这几个文件要选择“复制”：
