定时执行程序-Quartz简单实例
1、加jar包：Quartz自己quartz-1.8.3.jar和依赖包commons-logging.jar 、slf4j-log4j12-1.5.10.jar 、slf4j-api-1.5.10.jar
2、一个类搞定！！！，直接run
import org.quartz.CronTrigger; import org.quartz.Job; import org.quartz.JobDetail; import org.quartz.JobExecutionContext; import org.quartz.JobExecutionException; import org.quartz.Scheduler; import org.quartz.SchedulerFactory; import org.quartz.impl.StdSchedulerFactory;import java.util.Date;
public class QuartzReport implements Job{
public void execute(JobExecutionContext cntxt) throws JobExecutionException {
System.out.println( "输出："+cntxt.getJobDetail().getJobDataMap().get("name")+new Date()); } public static void main(String[] args) { try { SchedulerFactory schedFact=new StdSchedulerFactory(); Scheduler sched=schedFact.getScheduler(); sched.start(); JobDetail jobDetail=new JobDetail("a","b",QuartzReport.class); jobDetail.getJobDataMap().put("name","lucy"); CronTrigger trigger=new CronTrigger("c","d"); trigger.setCronExpression("0/1 * * * * ? " ); // 启动之后立即执行 每一秒继续重复。 sched.scheduleJob(jobDetail, trigger); } catch (Exception e) { e.printStackTrace(); } } } /** * 输出： *log4j:WARN No appenders could be found for logger (org.quartz.simpl.SimpleThreadPool). log4j:WARN Please initialize the log4j system properly. 输出：lucyWed Apr 13 15:11:54 CST 2011 输出：lucyWed Apr 13 15:11:55 CST 2011 输出：lucyWed Apr 13 15:11:56 CST 2011 输出：lucyWed Apr 13 15:11:57 CST 2011 输出：lucyWed Apr 13 15:11:58 CST 2011 输出：lucyWed Apr 13 15:11:59 CST 2011 输出：lucyWed Apr 13 15:12:00 CST 2011 输出：lucyWed Apr 13 15:12:01 CST 2011 输出：lucyWed Apr 13 15:12:02 CST 2011 输出：lucyWed Apr 13 15:12:03 CST 2011 输出：lucyWed Apr 13 15:12:04 CST 2011 输出：lucyWed Apr 13 15:12:05 CST 2011 输出：lucyWed Apr 13 15:12:06 CST 2011 输出：lucyWed Apr 13 15:12:07 CST 2011 输出：lucyWed Apr 13 15:12:08 CST 2011 输出：lucyWed Apr 13 15:12:09 CST 2011 输出：lucyWed Apr 13 15:12:10 CST 2011 输出：lucyWed Apr 13 15:12:11 CST 2011 输出：lucyWed Apr 13 15:12:12 CST 2011 输出：lucyWed Apr 13 15:12:13 CST 2011 输出：lucyWed Apr 13 15:12:14 CST 2011*/
