Java中的作业调度——quartz 博客分类： Java Java作业调度第三方框架

1.quartz简介

    关于quartz的介绍，请链接如下地址：http://baike.baidu.com/link?url=Gl0_SCWPJ8owyjM2ORBWd0En0Y2ppGZuGTfwAJFb5dA4OyrlEVmYAR6yG4QtG8O1x9j1U6JMJPXvSbRBU1Bn0RcZOctgFn_hdIG_-HtGYm7。

    此处不再累述！

 

2. 实例

    功能：每隔五秒打印出信息

    代码：

           

package com.zh.quartz;

import java.text.SimpleDateFormat;
import java.util.Date;

import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;

public class Quartz implements Job{

	@Override
	public void execute(JobExecutionContext arg0) throws JobExecutionException {
		// TODO Auto-generated method stub
		System.out.println("Hello quartz" + "--->"
		    + new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(new Date()));
		
	}

}

            

package com.zh.quartz;

import org.quartz.JobDetail;
import org.quartz.Scheduler;
import org.quartz.SchedulerException;
import org.quartz.SimpleTrigger;
import org.quartz.impl.StdSchedulerFactory;

public class QuartzMain {
   public static void main(String[] args){
	   QuartzMain quartz_main = new QuartzMain();
	   try{
		   quartz_main.startSchedule();
	   }catch(Exception e){
		   e.printStackTrace();
	   }
   }
   
   @SuppressWarnings("static-access")
   protected void startSchedule() throws SchedulerException{
	   //调度器
	   Scheduler scheduler = StdSchedulerFactory.getDefaultScheduler();
	   
	   //具体执行类
	   JobDetail jobDetail = new JobDetail("firstJob",
			   Scheduler.DEFAULT_GROUP,Quartz.class);
	   
	   //触发器定义每五秒一次
	   SimpleTrigger simpleTrigger = 
			   new SimpleTrigger("trigger",scheduler.DEFAULT_GROUP,10,5000);
	   
	   scheduler.scheduleJob(jobDetail,simpleTrigger);
	   scheduler.start();
   }
