Windows服務使用標准的Csharp編寫,任務調度框架采用開源的Quartz.NET。
首先創建Windows服務-JobService

其次創建類庫項目-JobLibrary
整體解決方案架構圖如下:

在JobLibary中添加Quartz.NET的Nuget包引用,添加之后,vs會自動添加一系列的依賴項,這些依賴項是必須的,別手抖刪掉了。

其次再添加Common.Logging.Log4Net1211的Nuget包,他是Log4net的另外一種實現,會自動添加log4net的依賴
所有添加的包如下圖:

下面開始添加任務,在libary中添加一個job類繼承IJob,並實現其接口
using System;
using Quartz;
namespace JobLibrary
{
public class Job : IJob
{
private static readonly Common.Logging.ILog logger = Common.Logging.LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
public void Execute(IJobExecutionContext context)
{
try
{
logger.Info("job開始");
using (System.IO.StreamWriter sw = new System.IO.StreamWriter("E:\\log.txt", true))
{
sw.WriteLine(DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss ") + " 吃飯---睡覺");
}
logger.Info("job結束");
}
catch (Exception e)
{
logger.Error(e.Message);
}
}
}
}
這個類就是你需要做的任務。我的任務是吃飯和睡覺。
然后再在JobService中添加JobLibrary的引用,並且添加如下代碼(需要同樣添加Nuget引用)
using Common.Logging;
using Quartz;
using Quartz.Impl;
using System.ServiceProcess;
namespace JobService
{
public partial class Service1 : ServiceBase
{
private IScheduler scheduler;
private readonly ILog logger;
public Service1()
{
InitializeComponent();
ISchedulerFactory schedulerFactory = new StdSchedulerFactory();
scheduler = schedulerFactory.GetScheduler();
logger = LogManager.GetLogger(GetType());
}
protected override void OnStart(string[] args)
{
logger.Info("Quartz服務成功啟動");
scheduler.Start();
}
protected override void OnStop()
{
scheduler.Shutdown(false);
}
}
}
代碼完成之后,需要配置quartz_jobs.xml,在JobService項目添加xml配置文件“quartz_jobs.xml”,並添加任務配置。
<?xml version="1.0" encoding="UTF-8"?>
<!-- This file contains job definitions in schema version 2.0 format -->
<job-scheduling-data xmlns="http://quartznet.sourceforge.net/JobSchedulingData" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.0">
<processing-directives>
<overwrite-existing-data>true</overwrite-existing-data>
</processing-directives>
<schedule>
<!--定義示例任務1 Job-->
<job>
<name>DemoJob1</name>
<group>DeomJobGroup</group>
<description>Quartz.Net示例任務1</description>
<job-type>JobLibrary.Job,JobLibrary</job-type>
<durable>true</durable>
<recover>false</recover>
</job>
<!--定義示例任務1 觸發器 每10秒執行一次DemoJob1任務-->
<trigger>
<cron>
<name>DemoJob1Trigger</name>
<group>DeomJobTriggerGroup</group>
<job-name>DemoJob1</job-name>
<job-group>DeomJobGroup</job-group>
<cron-expression>0/10 * * * * ?</cron-expression>
</cron>
</trigger>
</schedule>
</job-scheduling-data>
這個配置文件有個莫名其妙的bug,就是最上面那幾行不能有空行,不知道是什么情況,有知道伙計望告知。被這個坑了半天。
其次,在添加quartz.config配置文件
# You can configure your scheduler in either <quartz> configuration section # or in quartz properties file # Configuration section has precedence quartz.scheduler.instanceName = ServerScheduler # 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
然后就是app.config的quartz的配置了
<configSections>
<section name="quartz" type="System.Configuration.NameValueSectionHandler, System, Version=1.0.5000.0,Culture=neutral, PublicKeyToken=b77a5c561934e089"/>
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net"/>
<sectionGroup name="common">
<section name="logging" type="Common.Logging.ConfigurationSectionHandler, Common.Logging"/>
</sectionGroup>
</configSections>
然后就是編譯,記住quartz_jobs.xml和quartz.config這兩個文件一定要編譯輸出,要不然讀取不到。


啟動之后,就可以看到寫到文件中的內容了。
如果一台機器上跑任務,那么如果這太機器掛掉了怎么辦?如果是多台機器上跑任務,那么任務重復執行怎么辦?
