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)

测试工作类

//测试工作类//TestJob.javapackage 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.htmlcommons-beanutils.jar是http://jakarta.apache.org/commons/beanutilscommons-collections.jar是http://jakarta.apache.org/commons/collectionscommons-dbcp-1.1.jar是，假如用到数据库作为作业存储http://jakarta.apache.org/commons/dbcpcommons-digester.jar是假如你使用了某些插件，就需要它commons-logging.jar是http://jakarta.apache.org/commons/logging/commons-pool-1.1.jar http://jakarta.apache.org/commons/pool/javamail.jar发送 e-mail 用http://java.sun.com/products/javamail/jdbc2_0-stdext.jar是，假如用到数据库作为作业存储http://java.sun.com/products/jdbc/jta.jar是，假如用到数据库作为作业存储http://java.sun.com/products/jta/databasequartz.jar是Quart 框架核心包servlet.jar假如使用了Servlet 容器，但容器中应该存在http://java.sun.com/products/servlet/log4j.jar是，日志http://logging.apache.org/
