3. import java.util.Date;
4. import org.quartz.Job;
5. import org.quartz.JobExecutionContext;
6. import org.quartz.JobExecutionException;
7. import org.slf4j.Logger;

10. public class HelloJob
11. implements Job

14. throws JobExecutionException
15. {
16. System.out.println( "Hello World! - " + new Date());

37. //TriggerBuilder实例化一个触发器
38. Trigger trigger = TriggerBuilder.newTrigger() //创建一个新的TriggerBuilder用来规范一个触发器
39. .withIdentity( "trigger1", "group1") //给触发器一个名字和组名
40. .startAt(runTime) //设置触发开始的时间
41. .build(); //产生触发器
43. sched.scheduleJob(job, trigger); //向Scheduler添加一个job和trigger
