Quartz+TopShelf实现Windows服务作业调度

　　Quartz：首先我贴出来了两段代码（下方），可以看出，首先会根据配置文件（quartz.config），包装出一个Quartz.Core.QuartzScheduler

instance，这是一个调度器，调度各个任务项（Jobs）的执行。这个调度器可以被Start、被Shutdown、被PauseAll、被ResumeAll，这对应

了windows服务的开启、停止、暂停、恢复。当启动服务，我就调用调度器的Start()，停止服务我就调用调度器的Shutdown()方法。

namespace QTDemo
{
    public class ServiceRunner : ServiceControl, ServiceSuspend
    {
        private readonly IScheduler scheduler;

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

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

// 摘要: 
    //     An implementation of Quartz.ISchedulerFactory that does all of it's work
    //     of creating a Quartz.Core.QuartzScheduler instance based on the contents
    //     of a properties file.
    public class StdSchedulerFactory : ISchedulerFactory
    {
        public const string AutoGenerateInstanceId = "AUTO";
        public const string ConfigurationSectionName = "quartz";
        public const string DefaultInstanceId = "NON_CLUSTERED";
        public const string PropertiesFile = "quartz.config";

　　那TopShelf又扮演了什么样的角色呢

　　这是一个宿主服务的框架。和ServiceBase、ServiceInstaller那一套的目的一样，都是用来创建Windows服务的。

  

1、新建项目控制台应用程序‘QTDemo’

 

2、从NuGet安装‘Quartz’，‘Topshelf’，‘Topshelf.Log4Net’ 

1 <?xml version="1.0" encoding="utf-8"?>
2 <packages>
3   <package id="Common.Logging" version="3.3.1" targetFramework="net45" />
4   <package id="Common.Logging.Core" version="3.3.1" targetFramework="net45" />
5   <package id="log4net" version="2.0.5" targetFramework="net45" />
6   <package id="Quartz" version="2.3.3" targetFramework="net45" />
7   <package id="Topshelf" version="3.3.1" targetFramework="net45" />
8   <package id="Topshelf.Log4Net" version="3.3.1" targetFramework="net45" />
9 </packages>

 

3、定义一个Job（一个任务项），继承Quartz.IJob

 1 using Quartz;
 2 namespace QTDemo.QuartzJobs
 3 {
 4     public sealed class TestJob : IJob
 5     {
 6         public void Execute(IJobExecutionContext context)
 7         {
 8             CommonHelper.AppLogger.InfoFormat("TestJob测试");
 9 
10         }
11     }
12 }
13  

 

4、配置（新建）quartz.config、quartz_jobs.xml

quartz.config可直接使用，不用修改

 1 # You can configure your scheduler in either <quartz> configuration section
 2 # or in quartz properties file
 3 # Configuration section has precedence
 4 
 5 quartz.scheduler.instanceName = QuartzTest
 6 
 7 # configure thread pool info
 8 quartz.threadPool.type = Quartz.Simpl.SimpleThreadPool, Quartz
 9 quartz.threadPool.threadCount = 10
10 quartz.threadPool.threadPriority = Normal
11 
12 # job initialization plugin handles our xml reading, without it defaults are used
13 quartz.plugin.xml.type = Quartz.Plugin.Xml.XMLSchedulingDataProcessorPlugin, Quartz
14 quartz.plugin.xml.fileNames = ~/quartz_jobs.xml
15 
16 # export this server to remoting context
17 #quartz.scheduler.exporter.type = Quartz.Simpl.RemotingSchedulerExporter, Quartz
18 #quartz.scheduler.exporter.port = 555
19 #quartz.scheduler.exporter.bindName = QuartzScheduler
20 #quartz.scheduler.exporter.channelType = tcp
21 #quartz.scheduler.exporter.channelName = httpQuartz
