Quartz使用-入门使用(java定时任务实现)

注：这里使用的是Quartz1.6.5版本(包：quartz-1.6.5.jar)

 

 

 

//测试main函数 //QuartzTest.java package quartzPackage; import java.text.SimpleDateFormat; import java.util.Date; public class QuartzTest { /** *//** * @param args */ public static void main(String[] args) { // TODO Auto-generated method stub SimpleDateFormat DateFormat = new SimpleDateFormat("yyyyMMddHHmmss"); Date d = new Date(); String returnstr = DateFormat.format(d); TestJob job = new TestJob(); String job_name ="11"; try { System.out.println(returnstr+ "【系统启动】"); QuartzManager.addJob(job_name,job,"0/2 * * * * ?"); //每2秒钟执行一次 // Thread.sleep(10000); // System.out.println("【修改时间】"); // QuartzManager.modifyJobTime(job_name,"0/10 * * * * ?"); // Thread.sleep(20000); // System.out.println("【移除定时】"); // QuartzManager.removeJob(job_name); // Thread.sleep(10000); // // System.out.println("/n【添加定时任务】"); // QuartzManager.addJob(job_name,job,"0/5 * * * * ?"); } catch (Exception e) { e.printStackTrace(); } } }

测试工作类

//测试工作类 //TestJob.java package quartzPackage; import java.text.SimpleDateFormat; import java.util.Date; import org.quartz.Job; import org.quartz.JobExecutionContext; import org.quartz.JobExecutionException; public class TestJob implements Job { SimpleDateFormat DateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); Date d = new Date(); String returnstr = DateFormat.format(d); public void execute(JobExecutionContext arg0) throws JobExecutionException { // TODO Auto-generated method stub System.out.println(returnstr+"★★★★★★★★★★★"); } }

 

第三方包

通过测试。一个简单任务只需要以下几个包：commons-beanutils.jar、commons-collections.jar、commons-logging.jar、commons-digester.jar、quartz.jar即可

名称	必须/备注	网址
activation.jar	主要是 JavaMail 要用到	http://java.sun.com/products/javabeans/glasgow/jaf.html
commons-beanutils.jar	是	http://jakarta.apache.org/commons/beanutils
