Examples of Spring Quartz2 Dynamic Tasks

The SimpleScheduleBuilder class in Quartz is used here. Non-CronScheduleBuilder and CronScheduleBuilder are Cron expressions. For details, refer to Baidu.

Implementation Code:

/*** Add a task ** @ param scheduleJob * @ throws Exception */@ Override @ handle ("unchecked") public void addJobSimple (ScheduleJob scheduleJob) throws Exception {TriggerKey triggerKey = TriggerKey. triggerKey (scheduleJob. getJobName (), scheduleJob. getJobGroup (); // Trigger trigger Trigger = schedgger. 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 ("seconds ". equals (scheduleJob. getTimeType () | "second ". specified signorecase (scheduleJob. getTimeType () {simpleScheduleBuilder. withIntervalInSeconds (scheduleJob. getTimeValue ()). repeatForever ();} else if ("points ". equals (scheduleJob. getTimeType () | "Minute ". equals (scheduleJob. getTimeType () | "minute ". specified signorecase (scheduleJob. getTimeType () {simpleScheduleBuilder. withIntervalInMinutes (scheduleJob. getTimeValue ()). repeatForever ();} else if ("Hour ". equals (scheduleJob. getTimeType () | "Hour ". equals (scheduleJob. getTimeType () | "hour ". specified signorecase (scheduleJob. getTimeType () {simpleScheduleBuilder. withIntervalInHours (scheduleJob. getTimeValue ()). repeatForever ();} else if ("day ". equals (scheduleJob. getTimeType () | "date ". specified signorecase (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 simple task:" + JasonUtils. object2String (scheduleJob);} else {this. updateJobCron (scheduleJob );}}

Note that, when a scheduled task is executed only once, you need to carefully read the code. The preceding simple scheduled task was just like me at the beginning:

simpleScheduleBuilder.withIntervalInSeconds(scheduleJob.getTimeValue()); 

The result is executed only once, but what I need is continuous loop execution, and finally changed:

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

It can be seen that there is a repeatForever (), which indicates that the repeatForever is always repeated.

If you do not want to execute multiple times, use:. withRepeatCount (triggerRepeatCount) as follows:

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