此处使用的是Quartz中SimpleScheduleBuilder类，非CronScheduleBuilder，CronScheduleBuilder是Cron表达式的。具体请自行百度。

/**
	 * 新增任务
	 * @param scheduleJob
	 * @throws Exception 
	 */
	@Override
	@SuppressWarnings("unchecked")
	public void addJobSimple(ScheduleJob scheduleJob) throws Exception{
		TriggerKey triggerKey = TriggerKey.triggerKey(scheduleJob.getJobName(), scheduleJob.getJobGroup());
		//任务触发
		Trigger trigger = scheduler.getTrigger(triggerKey);
		if (null == trigger) {
			JobDetail jobDetail = JobBuilder.newJob((Class<? extends Job>) Class.forName(scheduleJob.getClazz()))
		      .withIdentity(scheduleJob.getJobName(), scheduleJob.getJobGroup()).build();
		    jobDetail.getJobDataMap().put("scheduleJob", scheduleJob);
		    
		    SimpleScheduleBuilder simpleScheduleBuilder = SimpleScheduleBuilder.simpleSchedule();
		    if("秒".equals(scheduleJob.getTimeType()) || 
		    		"second".equalsIgnoreCase(scheduleJob.getTimeType())){
		    	simpleScheduleBuilder.withIntervalInSeconds(scheduleJob.getTimeValue()).repeatForever();
		    }else if("分".equals(scheduleJob.getTimeType()) || "分钟".equals(scheduleJob.getTimeType()) || 
		    		"minute".equalsIgnoreCase(scheduleJob.getTimeType())){
		    	simpleScheduleBuilder.withIntervalInMinutes(scheduleJob.getTimeValue()).repeatForever();
		    }else if("时".equals(scheduleJob.getTimeType()) || "小时".equals(scheduleJob.getTimeType()) || 
		    		"hour".equalsIgnoreCase(scheduleJob.getTimeType())){
		    	simpleScheduleBuilder.withIntervalInHours(scheduleJob.getTimeValue()).repeatForever();
		    }else if("天".equals(scheduleJob.getTimeType()) || 
		    		"date".equalsIgnoreCase(scheduleJob.getTimeType())){
		    	simpleScheduleBuilder.withIntervalInHours(scheduleJob.getTimeValue()).repeatForever();
		    }
		    ScheduleBuilder<SimpleTrigger> schedBuilder = simpleScheduleBuilder.withMisfireHandlingInstructionNextWithRemainingCount();
		    
		    trigger =TriggerBuilder.newTrigger().withIdentity(scheduleJob.getJobName(), scheduleJob.getJobGroup())
		    		.withSchedule(schedBuilder).build();
		    trigger = TriggerBuilder.newTrigger().withIdentity(scheduleJob.getJobName(), scheduleJob.getJobGroup()).withSchedule(schedBuilder).build();
		    scheduler.scheduleJob(jobDetail, trigger);
		    log.info(CC.LOG_PREFIX + "新增简单任务："+JasonUtils.Object2String(scheduleJob));
		}else {
			this.updateJobCron(scheduleJob);
		}
	}

需要注意是的，当定时任务只执行一次时，就要仔细看代码，如上面的简单定时任务，刚开始是我这样的：

simpleScheduleBuilder.withIntervalInSeconds(scheduleJob.getTimeValue());

 结果只执行一次，而我需要的是不断循环执行，最后改成：

simpleScheduleBuilder.withIntervalInSeconds(scheduleJob.getTimeValue()).repeatForever();

可以看出，后面多了个：repeatForever()，表示永远重复。

如果是希望执行多少次后不执行，就使用：.withRepeatCount(triggerRepeatCount)，如下：

simpleScheduleBuilder.withIntervalInHours(scheduleJob.getTimeValue()).withRepeatCount(triggerRepeatCount);
