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。

Java代码


/**

* 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：

Java代码


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：

Java代码


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：

Java代码


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