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();        }    }}
