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();
        }
    }
}
