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);
