Spring Quartz2 動(dòng)態(tài)任務(wù)的實(shí)例詳解
此處使用的是Quartz中SimpleScheduleBuilder類，非CronScheduleBuilder，CronScheduleBuilder是Cron表達(dá)式的。具體請(qǐng)自行百度。
實(shí)現(xiàn)代碼：
/**
* 新增任務(wù)
* @param scheduleJob
* @throws Exception
*/
@Override
@SuppressWarnings("unchecked")
public void addJobSimple(ScheduleJob scheduleJob) throws Exception{
TriggerKey triggerKey = TriggerKey.triggerKey(scheduleJob.getJobName(), scheduleJob.getJobGroup());
//任務(wù)觸發(fā)
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()) || "分鐘".equals(scheduleJob.getTimeType()) ||
"minute".equalsIgnoreCase(scheduleJob.getTimeType())){
simpleScheduleBuilder.withIntervalInMinutes(scheduleJob.getTimeValue()).repeatForever();
}else if("時(shí)".equals(scheduleJob.getTimeType()) || "小時(shí)".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();
}
ScheduleBuilderSimpleTrigger> 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 + "新增簡(jiǎn)單任務(wù)："+JasonUtils.Object2String(scheduleJob));
}else {
this.updateJobCron(scheduleJob);
}
}
需要注意是的，當(dāng)定時(shí)任務(wù)只執(zhí)行一次時(shí)，就要仔細(xì)看代碼，如上面的簡(jiǎn)單定時(shí)任務(wù)，剛開(kāi)始是我這樣的：
simpleScheduleBuilder.withIntervalInSeconds(scheduleJob.getTimeValue());
結(jié)果只執(zhí)行一次，而我需要的是不斷循環(huán)執(zhí)行，最后改成：
simpleScheduleBuilder.withIntervalInSeconds(scheduleJob.getTimeValue()).repeatForever();
可以看出，后面多了個(gè)：repeatForever()，表示永遠(yuǎn)重復(fù)。
如果是希望執(zhí)行多少次后不執(zhí)行，就使用：.withRepeatCount(triggerRepeatCount)，如下：
simpleScheduleBuilder.withIntervalInHours(scheduleJob.getTimeValue()).withRepeatCount(triggerRepeatCount);
