Quartz.2.1.x Job Scheduling

Quartz2.1.x multi-task execution case

1. Add a jar package

[Html]
<Dependency>
<GroupId> org. quartz-scheduler </groupId>
<ArtifactId> quartz </artifactId>
<Version> 2.1.0 </version>
</Dependency>

2. Create a task
[Java]
/**
* Add a task
* @ Param scheduler
* @ Param jobName
* @ Param jobGroup
* @ Param cron
*/
Private void addJob (Scheduler schedname, String jobName, String jobGroup, String cron ){
Try {
JobDetail jobOne = JobBuilder. newJob (GbSimpleJob. class). withIdentity (jobName, jobGroup). build ();
CronTrigger trgOne = TriggerBuilder. newTrigger (). withIdentity (jobName, jobGroup)
. WithSchedule (CronScheduleBuilder. cronSchedule (cron) // [0 0/1 ***?] Run Once every minute
. ForJob (jobName, jobGroup). build ();
Scheduler. scheduleJob (jobOne, trgOne );
} Catch (ParseException e ){
E. printStackTrace ();
} Catch (SchedulerException e ){
E. printStackTrace ();
}
}
