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.
/**

*/
package org.yq.myQuartz.jobs;
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.quartz.Job;
import org.quartz.JobDataMap;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.yq.myQuartz.utils.MailJobUtil;
/**
* @ MailJob.java
* 描述:

*/
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.

public class myEmailQuartz {
public void run() throws Exception {
Log log = LogFactory.getLog(myEmailQuartz.class);
log.info("------- Initializing -------------------");
// First we must get a reference to a scheduler
SchedulerFactory sf = new StdSchedulerFactory();
Scheduler sched = sf.getScheduler();
log.info("------- Initialization Complete --------");
log.info("------- Scheduling Jobs ----------------");
JobDetail job1 = new JobDetail("job1", "group1", MailJob.class);
Trigger trigger = TriggerUtils.makeDailyTrigger(23, 00); //每日 23:00触发工作执行
trigger.setName("trigger1");
trigger.setGroup("group1");
trigger.setJobName("job1");
trigger.setJobGroup("group1");
// pass initialization parameters into the job
job1.getJobDataMap().put(MailJob.FROMMAIL, "*****");
job1.getJobDataMap().put(MailJob.TOMAIL, "*****");
job1.getJobDataMap().put(MailJob.CONTENT, "*****");
job1.getJobDataMap().put(MailJob.SUBJECT, "*****");
// schedule the job to run
Date scheduleTime1 = sched.scheduleJob(job1, trigger);
log.info(job1.getFullName() +
" will run at: " + scheduleTime1);
log.info(job1.getFullName() +
" will run at: " + scheduleTime1 );
log.info("------- Starting Scheduler ----------------");
// All of the jobs have been added to the scheduler, but none of the jobs
// will run until the scheduler has been started
sched.start();
log.info("------- Started Scheduler -----------------");
log.info("------- Waiting 60 seconds... -------------");
try {
// wait five minutes to show jobs
Thread.sleep(60L * 1000L);
// executing...
} catch (Exception e) {
}
log.info("------- Shutting Down ---------------------");
sched.shutdown(true);
log.info("------- Shutdown Complete -----------------");
SchedulerMetaData metaData = sched.getMetaData();
log.info("Executed " + metaData.numJobsExecuted() + " jobs.");
}
public static void main(String[] args) throws Exception {
myEmailQuartz example = new myEmailQuartz();
example.run();
}
}
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!
