僅作備忘 SchedulerFactoryBean： 1、public void afterPRopertiesSet() throws Exception 2、// Create SchedulerFactory instance. SchedulerFactory schedulerFactory = (SchedulerFactory) BeanUtils.instantiateClass(this.schedulerFactoryClass); （private Class</?> schedulerFactoryClass = StdSchedulerFactory.class;）

StdSchedulerFactory： 1、private Scheduler instantiate() throws SchedulerException 2、1248-QuartzSchedulerResources rsrcs = new QuartzSchedulerResources(); 3、1298-qs = new QuartzScheduler(rsrcs, idleWaitTime, dbFailureRetry);

實際還是利用的StdSchedulerFactory類做為工廠類。
