Quartz.NET的应用 | 易学教程

Quartz.NET 是一个开源的调度框架，什么是调度，有什么用，简单的说，如果你有这样的需求，你就可以用它来帮你。如一个在两个系统中同步数据的程序，需要在每天晚上运行。也就是说它能在一个相对固定的时间重复做同样一件事情。当然做什么事需要你自己来写了。以前写这样的程序多半是用一个控制台程序，然后加到windows的任务列表中。
看看QUarz.NET官方(http://quartznet.sourceforge.net/)的描述吧
Quartz.NET is a full-featured, open source job scheduling system that can be used from smallest apps to large scale enterprise systems.
Quartz.NET is a port of very propular open source Java job scheduling framework, Quartz . This project owes very much to original Java project, it's father James House and the project contributors.
又是一个从java移植过来的好东西，呵呵！不得不感叹java的发展速度和其所拥有的用户群。

Quartz.net的使用还是比较简单的，我用三步曲来描述
一步配置
<?xml version="1.0" encoding="UTF-8"?>
<quartz xmlns="http://quartznet.sourceforge.net/JobSchedulingData"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    version="1.0"
    overwrite-existing-jobs="true">
<job>
  <job-detail>
   <name>mytask</name>
   <group>tasks</group>
   <job-type>SchedulerLibrary.MyTask, SchedulerLibrary</job-type>
  </job-detail>
<trigger>
  <cron>
   <name>CronTrigger</name>
   <group>TriggerGroup</group>
   <job-name>mytask</job-name>
   <job-group>tasks</job-group>
   <start-time>2008-02-24T05:00:01</start-time>
   <cron-expression>0 0 5 * * ?</cron-expression>
  </cron>
</trigger>
</job>
</quartz>
二步初始化IScheduler

public partial class MyService : ServiceBase
    {
        private ISchedulerFactory schedulerFactory;
        private JobSchedulingDataProcessor processor;
        private static log4net.ILog logger = log4net.LogManager.GetLogger(typeof(MyService));

        public MyService()
        {
            InitializeComponent();

            schedulerFactory = new StdSchedulerFactory();
            processor = new JobSchedulingDataProcessor(true, true);
        }

        protected override void OnStart(string[] args)
        {
            try
            {
                IScheduler scheduler = schedulerFactory.GetScheduler();
                string fileName = AppDomain.CurrentDomain.BaseDirectory + System.Configuration.ConfigurationManager.AppSettings["JobConfigFile"];
                processor.ProcessFile(fileName, null);
                processor.ScheduleJobs(new Hashtable(), scheduler, false);

scheduler.Start();

                logger.Info("service started ok");
            }
            catch (Exception ex)
            {
                logger.Error("service started fail", ex);
            }
        }

        protected override void OnStop()
        {
            try
            {
                IScheduler scheduler = schedulerFactory.GetScheduler();
                scheduler.Shutdown(true);

                logger.Info("service stopped ok");
            }
            catch (Exception ex)
            {
                logger.Error("service stopped fail", ex);
            }
        }

三步实现任务

public class MyTask : IJob
{
#region IJob Members

public void Execute(JobExecutionContext context)
{

//todo
}

#endregion
}

其实只要实现iJob接口即可。
