Cron Expression每月工作

Question

I want run scheduler job 14th of each month, if this day falls on a weekend, scheduler job should be day prior to this day. What is the cron expression for this?.

I'm guessing you could extend CronTriggerImpl to create a NotOnWeekendsCronTrigger . Eg:

public class NotOnWeekendsCronTrigger extends CronTriggerImpl {
    public Date getFireTimeAfter(Date afterTime) {
       return weekdayBefore(super.getFireTimeAfter(afterTime));
    }
    public Date getNextFireTime() {
       return weekdayBefore(super.getNextFireTime());
    }
    protected Date weekdayBefore(Date date) {
       // TODO implement
    }
    // etc etc
}
