Quartz是一款全功能的开源的任务调度服务。

官方网址：http://www.quartz-scheduler.org/

文中使用的Quartz是1.8.6版本，基础依赖包有：

具体使用见代码：

/**
 * @author yanlei
 * 任务执行类，必须实现Job接口
 */
public class FirstJob implements Job {

	public void execute(JobExecutionContext context)
			throws JobExecutionException {
		// 通过任务执行体获取任务数据
		JobDetail jobDetail = context.getJobDetail();
		
		// 输出任务的一些信息
		System.out.println("Job's information:");
		System.out.println("Name:" + jobDetail.getName());
		System.out.println("GroupName:" + jobDetail.getGroup());
	}

}

/**
 * Quartz任务实例
 * @author yanlei
 */
public class JobTest {
	private static final String jobName = "firstJob";
	private static final String jobGroupName = "GROUP_1";
	private static final String triggerName = "trigger_1";
	private static final String triggerGroupName = "trigger_group_1";

	public static void main(String[] args) {

		try {
			// 获取调度器
			Scheduler scheduler = StdSchedulerFactory.getDefaultScheduler();

			// 创建任务数据，FirstJob是任务的执行类
			JobDetail jobDetail = new JobDetail(jobName, jobGroupName,
					FirstJob.class);

			/*
			 * 将任务放入调度器，并设置触发器 SimpleTrigger是Quartz支持的四类触发器之一，具体信息参考API
			 */
			scheduler.scheduleJob(jobDetail, new SimpleTrigger(triggerName,
					triggerGroupName));

			// 开启任务调度器
			scheduler.start();

			System.out.println("Job is running");

			// 停止任务调度器
			scheduler.shutdown();
		} catch (SchedulerException e) {
			e.printStackTrace();
		}
	}

}

输出信息：
