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); } } }
代码很简单,配置文件中的quartz基础配置,以及job,trigger信息是如何加载的?这个过程是发生 IScheduler sched = sf.GetScheduler();过程,主要体现在源码这一段
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 findconfiguration 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
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.config 中plugin配置指向(quartz.plugin.xml.type / quartz.plugin.xml.fileNames)
# You can configure your scheduler in eitherconfiguration 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() .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
