public class Test {

	/**
	 * @param args
	 */
    public static void main(String[] args) { 
        //1、创建JobDetial对象 
        JobDetail jobDetail = new JobDetail(); 
        //设置工作项 
        jobDetail.setJobClass(MyJob.class); 
        jobDetail.setName("MyJob_1"); 
        jobDetail.setGroup("JobGroup_1"); 

        //2、创建Trigger对象 
        SimpleTrigger strigger = new SimpleTrigger(); 
        strigger.setName("Trigger_1"); 
        strigger.setGroup("Trigger_Group_1");

        //设置重复执行次数 
        strigger.setRepeatCount(strigger.REPEAT_INDEFINITELY); 
        

        //3、创建Scheduler对象，并配置JobDetail和Trigger对象 
        SchedulerFactory sf = new StdSchedulerFactory(); 
        Scheduler scheduler = null; 
        try { 
                scheduler = sf.getScheduler(); 
                scheduler.scheduleJob(jobDetail, strigger); 
                //4、并执行启动、关闭等操作 
                scheduler.start(); 

        } catch (SchedulerException e) { 
                e.printStackTrace(); 
        } 
        
        
//        try { 
//                //关闭调度器 
//                scheduler.shutdown(true); 
//        } catch (SchedulerException e) { 
//                e.printStackTrace();
