Quartz是一个Java开源的作业调度框架。官方网站:http://www.opensymphony.com/quartz/ IBM网站上有一篇简单易懂的文章:http://www.ibm.com/developerworks/cn/java/j-quartz/Quartz.net是从java版本移植到.net版本的。官方网站:http://quartznet.sourceforge.net/ 网上找了好多教程,但没有一篇是关于如何在ASP.NET中使用的代码。既然它适用于任何的.net程序,当然也就适用于asp.net的web应用。(1)在web.config中进行相关配置
< configSections > < section name ="quartz" type ="System.Configuration.NameValueSectionHandler, System, Version=1.0.5000.0,Culture=neutral, PublicKeyToken=b77a5c561934e089" /> < sectionGroup name ="common" > < section name ="logging" type ="Common.Logging.ConfigurationSectionHandler, Common.Logging" /> </ sectionGroup > </ configSections > < common > < logging > < factoryAdapter type ="Common.Logging.Simple.ConsoleOutLoggerFactoryAdapter, Common.Logging" > < arg key ="showLogName" value ="true" /> < arg key ="showDataTime" value ="true" /> < arg key ="level" value ="DEBUG" /> < arg key ="dateTimeFormat" value ="HH:mm:ss:fff" /> </ factoryAdapter > </ logging > </ common > < 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" /> </ quartz > 另外我自己加了一个配置项: < appSettings > < add key ="cronExpr" value ="0 0 8-17/1 ? * 2-6" /> </ appSettings > (2)创建一个普通类,实现Quartz.IJob接口 public class RetrieveAj2003T140Job : Quartz.IJob { private static DataView aj2003View; public RetrieveAj2003T140Job() { // // TODO: 在此处添加构造函数逻辑 // } public void Execute(Quartz.JobExecutionContext context) { //throw new Exception("The method or operation is not implemented."); //你的处理逻辑,也就是“工作” }} 接口非常简单,只要在Execute()方法中进行逻辑处理就可以了。比如,读取数据库数据,或者是读取电子邮件。 (3)在Global.asax文件中启动工作调度这便于我们在web应用启动时,就启动工作调度。 <% @ Import Namespace = " Quartz " %> < script runat = " server " > IScheduler sched; void Application_Start( object sender, EventArgs e) { // 在应用程序启动时运行的代码 ISchedulerFactory sf = new Quartz.Impl.StdSchedulerFactory(); sched = sf.GetScheduler(); JobDetail job = new JobDetail("job1", "group1", typeof(RetrieveAj2003T140Job)); string cronExpr = ConfigurationManager.AppSettings["cronExpr"]; CronTrigger trigger = new CronTrigger("trigger1", "group1", "job1", "group1",cronExpr); sched.AddJob(job, true); DateTime ft = sched.ScheduleJob(trigger); sched.Start(); } void Application_End( object sender, EventArgs e) { // 在应用程序关闭时运行的代码 if (sched != null) { sched.Shutdown(true); } } </ script > 需要注意的是,当Application_End的时候,需要关闭Quartz的工作。 OK了,可以在ASP.NET中正常使用了。
