【C015286】在Spring-Quartz的应用中：

public static void main(String[] args) throws Throwable {  

        SchedulerFactory factory = new StdSchedulerFactory();  

        Scheduler scheduler = factory.getScheduler();  

        JobDetail job = JobBuilder.newJob(MyJob.class).withIdentity("job1", "group1").build();  

        CronTrigger trigger = ___; 

        scheduler.scheduleJob(job, trigger);

        scheduler.start();

    }

}

假如触发器计划每10秒执行一次，则横线处正确答案为（）。

• A.TriggerBuilder.newTrigger().withIdentity("trigger1", "group1")  
  
                  .withSchedule(CronScheduleBuilder.cronSchedule("0/13 * * * * ?")).build();

• B.TriggerBuilder.newTrigger().withIdentity("trigger1", "group1")  
  
                  .withSchedule(CronScheduleBuilder.cronSchedule("0/15 * * * * ?"));

• C.TriggerBuilder.newTrigger().build(CronScheduleBuilder.cronSchedule("0/15 * * * * ?"));

• D.TriggerBuilder.newTrigger().withSchedule("trigger1", "group1")  
  
                  .withIdentity(CronScheduleBuilder.cronSchedule("0/15 * * * * ?")).build();
