总结：
Spring与Quartz的整合关键在于SchedulerFactoryBean，我们在XML中配SchedulerFactoryBean时候，如要需要任务持久化，我们需要配置datasource，配置Quartz属性（线程池， 调度器名，线程池优先级，持久化类等信息），配置jobDetails，配置触发任务trrigers（TrrigerWapper），延迟加载属性，监听器，重写属性；SchedulerFactoryBean实现了InitializingBean，在SchedulerFactoryBean属性初始化完毕，调用afterPropertiesSet方法，完成数据源，Quartz-schedulerFactory初始化，创建调度器，初始化调度器上下文，注册监听器，注册job，Trrigers。
