                   Scheduler scheduler =            JobDetail jobDetail ="cronTriggerDetail", "cronTriggerDetailGrounp"            JobDataMap jobDataMap ="name", "cronTriggerMap""group", "cronTriggerGrounp"            CronTrigger cronTrigger =                                        newTrigger().                                        withIdentity("cronTrigger", "cronTrigger""0 48 14 * * ?"                                        build();            

The above is the simple use of CronTrigger of Version 2.0. You can schedule tasks based on specific services.
