/**
* Convenience subclass of Quartz's {@link org.quartz.CronTrigger}
* class, making bean-style usage easier.
*
* CronTrigger itself is already a JavaBean but lacks sensible defaults.
* This class uses the Spring bean name as job name, the Quartz default group
* ("DEFAULT") as job group, the current time as start time, and indefinite
* repetition, if not specified.
*
*
This class will also register the trigger with the job name and group of
* a given {@link org.quartz.JobDetail}. This allows {@link SchedulerFactoryBean}
* to automatically register a trigger for the corresponding JobDetail,
* instead of registering the JobDetail separately.
*
*
NOTE: This convenience subclass does not work with trigger
* persistence in Quartz 1.6, due to a change in Quartz's trigger handling.
* Use Quartz 1.5 if you rely on trigger persistence based on this class,
* or the standard Quartz {@link org.quartz.CronTrigger} class instead.
