The SimpleScheduleBuilder class in Quartz is used here, not CronScheduleBuilder, CronScheduleBuilder is a Cron expression. Please refer to Baidu for details.
/**
* Added tasks
* @param scheduleJob
* @throws Exception
*/
@Override
@SuppressWarnings("unchecked")
public void addJobSimple(ScheduleJob scheduleJob) throws Exception{
TriggerKey triggerKey = TriggerKey.triggerKey(scheduleJob.getJobName(), scheduleJob.getJobGroup());
// task trigger
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 + "Add a simple task: "+JasonUtils.Object2String(scheduleJob));
}else {
this.updateJobCron(scheduleJob);
}
}
It should be noted that, when the scheduled task is only executed once, you must look at the code carefully, such as the simple scheduled task above. At the beginning, I was like this:
simpleScheduleBuilder.withIntervalInSeconds(scheduleJob.getTimeValue());
The result is only executed once, and what I need is to continuously execute in a loop, and finally changed to:
simpleScheduleBuilder.withIntervalInSeconds(scheduleJob.getTimeValue()).repeatForever();
It can be seen that there is one more behind: repeatForever(), which means repeat forever.
If you want to execute how many times and then not execute, use: .withRepeatCount(triggerRepeatCount), as follows:
simpleScheduleBuilder.withIntervalInHours(scheduleJob.getTimeValue()).withRepeatCount(triggerRepeatCount);
