創建一個任務調度

Scheduler scheduler = StdSchedulerFactory.getDefaultScheduler();//Schedulers can be immediately used to schedule jobs, but they will not start executing any until the .start()scheduler.start();//And then schedule those jobs with triggers that define at what time(s) the job should run.JobDetail job = newJob(Myjob.class).withIdentity("job1", "group1").build();// Trigger the job to run now, and then repeat every 40 secondsTrigger trigger = newTrigger().withIdentity("trigger1", "group1").startNow().withSchedule(simpleSchedule().withIntervalInSeconds(2).repeatForever()).build();// Tell quartz to schedule the job using our triggerscheduler.scheduleJob(job, trigger);

任務類

public class Myjob implements Job {

public Myjob() {System.out.println("do");}
// you can implement Jobs - which have an .execute(..) method.
public void execute(JobExecutionContext jobExecutionContext) throws JobExecutionException {System.err.println("Hello World!  MyJob is executing.");System.out.println(this);
}

}

如果是Cron表達式

Trigger trigger = newTrigger().withIdentity("trigger1", "group1").startNow()//Build a trigger that will fire every other second, between 8am and 5pm, every day:.withSchedule(cronSchedule("0/2 * 8-17 * * ?")).build();
