这篇文章主要为大家详细介绍了Quartz.Net调度框架的配置方法,具有一定的参考价值,感兴趣的小伙伴们可以参考一下

在平时的工作中,估计大多数都做过轮询调度的任务,比如定时轮询数据库同步,定时邮件通知等等。大家通过windows计划任务,windows服务等都实现过此类任务,甚至实现过自己的配置定制化的框架。那今天就来介绍个开源的调度框架Quartz.Net(主要介绍配置的实现,因为有朋友问过此类问题)。调度的实现代码很简单,在源码中有大量Demo,这里就略过了。

Quartz.Net当前最新版本Quartz.NET 2.0 beta 1 Released

一、基于文件配置

先看一下简单的实现代码

using System;  using System.Collections.Generic;  using System.Linq;  using System.Text;  using System.Threading;  using Quartz;  using Quartz.Impl;  using Common.Logging;    namespace Demo  {   class Program   {    static void Main(string[] args)    {          // First we must get a reference to a scheduler     ISchedulerFactory sf = new StdSchedulerFactory();     IScheduler sched = sf.GetScheduler();          sched.Start();        sched.Shutdown(true);         }   }  }
 public void Initialize()    {     // short-circuit if already initialized     if (cfg != null)     {      return;     }     if (initException != null)     {      throw initException;     }       NameValueCollection props = (NameValueCollection) ConfigurationManager.GetSection("quartz");       string requestedFile = Environment.GetEnvironmentVariable(PropertiesFile);     string propFileName = requestedFile != null && requestedFile.Trim().Length > 0 ? requestedFile : "~/quartz.config";       // check for specials     propFileName = FileUtil.ResolveFile(propFileName);       if (props == null && File.Exists(propFileName))     {      // file system      try      {       PropertiesParser pp = PropertiesParser.ReadFromFileResource(propFileName);       props = pp.UnderlyingProperties;       Log.Info(string.Format("Quartz.NET properties loaded from configuration file '{0}'", propFileName));      }      catch (Exception ex)      {       Log.Error("Could not load properties for Quartz from file {0}: {1}".FormatInvariant(propFileName, ex.Message), ex);      }       }     if (props == null)     {      // read from assembly      try      {       PropertiesParser pp = PropertiesParser.ReadFromEmbeddedAssemblyResource("Quartz.quartz.config");       props = pp.UnderlyingProperties;       Log.Info("Default Quartz.NET properties loaded from embedded resource file");      }      catch (Exception ex)      {       Log.Error("Could not load default properties for Quartz from Quartz assembly: {0}".FormatInvariant(ex.Message), ex);      }     }     if (props == null)     {      throw new SchedulerConfigException(       @"Could not find <quartz> configuration section from your application config or load default configuration from assembly.  Please add configuration to your application config file to correctly initialize Quartz.");     }     Initialize(OverrideWithSysProps(props));    }

通过上面代码分析,初始化首先会检查系统config中是否有<quartz> configuration section节点 (config指的app.config,web.config),如果系统config有quartz节点,则直接加载此处的配置信息。如果系统config没有quartz的基础配置信息,则会继续查找是否有quartz.config/Quartz.quartz.config 这两个配置文件的存在,如果有则加载配置信息,如果没有则扔出初始化配置异常。

而jobs.xml(调度的任务和触发器plugin节点配置文件)

app.config/web.config 中plugin配置

 <quartz>    <add key="quartz.scheduler.instanceName" value="ExampleDefaultQuartzScheduler"/>    <add key="quartz.threadPool.type" value="Quartz.Simpl.SimpleThreadPool, Quartz"/>    <add key="quartz.threadPool.threadCount" value="10"/>    <add key="quartz.threadPool.threadPriority" value="2"/>    <add key="quartz.jobStore.misfireThreshold" value="60000"/>    <add key="quartz.jobStore.type" value="Quartz.Simpl.RAMJobStore, Quartz"/>   <!--******************************Plugin配置********************************************* -->   <add key="quartz.plugin.xml.type" value="Quartz.Plugin.Xml.XMLSchedulingDataProcessorPlugin, Quartz" />   <add key="quartz.plugin.xml.fileNames" value="quartz_jobs.xml"/>    </quartz>

quartz.config 中plugin配置指向(quartz.plugin.xml.type / quartz.plugin.xml.fileNames)

# 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    #--------------------------------*************plugin配置------------------------------------  # 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

二、基于代码的方式

这种情况直接通过代码实现的,官方DEMO很多都是如此,我们举个例子

using System;  using System.Collections.Generic;  using System.Linq;  using System.Text; using Quartz;  using Quartz.Impl;  using System.Threading;  using Common.Logging;    namespace Demo  {   class Program   {    static void Main(string[] args)    {     ILog log = LogManager.GetLogger(typeof(Demo.HelloJob));       log.Info("------- Initializing ----------------------");       // First we must get a reference to a scheduler     ISchedulerFactory sf = new StdSchedulerFactory();     IScheduler sched = sf.GetScheduler();       log.Info("------- Initialization Complete -----------");         //---------------------------------------代码添加job和trigger     // computer a time that is on the next round minute     DateTimeOffset runTime = DateBuilder.EvenMinuteDate(DateTimeOffset.UtcNow);       log.Info("------- Scheduling Job -------------------");       // define the job and tie it to our HelloJob class     IJobDetail job = JobBuilder.Create<HelloJob>()      .WithIdentity("job1", "group1")      .Build();       // Trigger the job to run on the next round minute     ITrigger trigger = TriggerBuilder.Create()      .WithIdentity("trigger1", "group1")      .StartAt(runTime)      .Build();       // Tell quartz to schedule the job using our trigger     sched.ScheduleJob(job, trigger);     log.Info(string.Format("{0} will run at: {1}", job.Key, runTime.ToString("r")));       // Start up the scheduler (nothing can actually run until the      // scheduler has been started)     sched.Start();     log.Info("------- Started Scheduler -----------------");       // wait long enough so that the scheduler as an opportunity to      // run the job!     log.Info("------- Waiting 65 seconds... -------------");       // wait 65 seconds to show jobs     Thread.Sleep(TimeSpan.FromSeconds(65));       // shut down the scheduler     log.Info("------- Shutting Down ---------------------");     sched.Shutdown(true);     log.Info("------- Shutdown Complete -----------------");    }   }  }

其实代码方式已经实现了和配置文件混搭的方式了。但是这种对方式是通过配置关联加载job与trigger配置,我们还有第三种方式,自己加载job与trigger配置文件。

三、手动加载配置文件

using System;  using System.Collections.Generic;  using System.Linq;  using System.Text;   using Quartz;  using Quartz.Xml;  using Quartz.Impl;  using Quartz.Simpl;  using System.Threading;  using Common.Logging;  using System.IO;    namespace Demo  {   class Program   {    static void Main(string[] args)    {         XMLSchedulingDataProcessor processor = new XMLSchedulingDataProcessor(new SimpleTypeLoadHelper());     ISchedulerFactory sf = new StdSchedulerFactory();     IScheduler scheduler = sf.GetScheduler();       Stream s = new StreamReader("~/quartz.xml").BaseStream;     processor.ProcessStream(s, null);     processor.ScheduleJobs(scheduler);       scheduler.Start();     scheduler.Shutdown();         }   }  }

亦或者这样

using System.Text;   using Quartz;  using Quartz.Xml;  using Quartz.Impl;  using Quartz.Simpl;  using System.Threading;  using Common.Logging;  using System.IO;    namespace Demo  {   class Program   {    static void Main(string[] args)    {         XMLSchedulingDataProcessor processor = new XMLSchedulingDataProcessor(new SimpleTypeLoadHelper());     ISchedulerFactory sf = new StdSchedulerFactory();     IScheduler scheduler = sf.GetScheduler();            processor.ProcessFileAndScheduleJobs("~/quartz.xml",scheduler);          scheduler.Start();     scheduler.Shutdown();         }   }  }

目前根据源码分析大致就这几种配置方式,很灵活可以任意组合。 关于quartz的使用源码很详细,并且园子量有大量的学习文章。

记住quartz的配置读取方式首先app.config/web.config ---->quartz.config/Quartz.quartz.config ---->quartz_jobs.xml .

通过代码方式我们可以改变quartz_jobs.xml 的指向即自己新命名的xml文件

(默认的quartz_jobs.xml是在XMLSchedulingDataProcessor.QuartzXmlFileName = "quartz_jobs.xml"被指定的)

方式一,通过quartz节点/quartz.config指向指定的jobs.xml。

方式二,通过XMLSchedulingDataProcessor 加载指定的jobs.xml
