定時執行程序-Quartz簡單實例

1、加jar包：Quartz自己quartz-1.8.3.jar和依賴包commons-logging.jar? 、slf4j-log4j12-1.5.10.jar 、slf4j-api-1.5.10.jar

2、一個類搞定！！！，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( "輸出："+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 * * * * ? " ); // 啟動之后立即執行 每一秒繼續重復。
??????????? sched.scheduleJob(jobDetail, trigger);
???????????
??????? }?? catch? (Exception e)?? {
??????????? e.printStackTrace();
??????? }
??? }
}?
