如视频导入文件和路径

package quartz;

import java.util.Date;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;

public class HelloJob implements Job 

public HelloJob() 


public void execute(JobExecutionContext context)
    throws JobExecutionException 
    System.out.println("---start---");
    System.out.println("Hello World! - " + new Date());
    System.out.println("---end---");

第二个class

package quartz;

import static org.quartz.JobBuilder.newJob;
import static org.quartz.TriggerBuilder.newTrigger;
import static org.quartz.DateBuilder.evenSecondDateAfterNow;

import java.util.Date;

import org.quartz.JobDetail;
import org.quartz.Scheduler;
import org.quartz.SchedulerFactory;
import org.quartz.Trigger;
import org.quartz.impl.StdSchedulerFactory;

/*
quarz

 */
public class SimpleExample 

    public void run() throws Exception 

  //1、创建Scheduler的工厂
SchedulerFactory sf = new StdSchedulerFactory();
//2、从工厂中获取调度器
Scheduler sched = sf.getScheduler();

//3、创建JobDetail
JobDetail job = newJob(HelloJob.class).withIdentity("job1", "group1").build();

//时间,下一秒
Date runTime = evenSecondDateAfterNow();
//4、触发器
Trigger trigger = newTrigger().withIdentity("trigger1", "group1").startAt(runTime).build();
//5、注册任务和触发条件
sched.scheduleJob(job, trigger);
//6、启动
sched.start();

try 
  // 5秒后停止
  Thread.sleep(5L*1000L);
  // executing...
 catch (Exception e) 
  //

sched.shutdown(true);

    

    public static void main(String[] args) throws Exception 

        SimpleExample example = new SimpleExample();
        example.run();
