Quartz是一个开源的作业调度框架，它完全由Java写成，并设计用于J2SE和J2EE应用中。下面介绍在J2SE中应用的邮件发送工作调度程序.
           Quartz要运行起来,最简单需要1. ***Job  自己实现的工作类 ;2. ***Quartz 调度你实现的工作类.
           一.  ***Job.java 实现Quartz框架的Job接口.

public class MailJob implements Job{

private static Log _log = LogFactory.getLog(MailJob.class);
   
    public static final String FROMMAIL = "fromMail";
    public static final String TOMAIL = "toMail";
    public static final String CONTENT = "content";
    public static final String SUBJECT = "subject";

public void execute(JobExecutionContext context) throws JobExecutionException {
        JobDataMap data = context.getJobDetail().getJobDataMap();
        MailJobUtil.sendMail(data.getString(FROMMAIL),
                data.getString(TOMAIL), data.getString(CONTENT), data.getString(SUBJECT));
       
    }

}
二.  ***Quartz.java 调度自己实现的Job类,主要是通过Quartz中的触发器用来告诉调度程序作业什么时候触发.

至此,一个简单的应用Quartz进行日发送邮件的程序已经完成.

上面这个邮件发送程序非常实用,很多系统都应该可以用到,要应用于WEB应用需要改动的地方也不多.希望大家试试改造一番,用于自己的网站,不过很多网站已经有这样的应用了,哈哈!
