quartz主要是三個部分：Scheduler Job Trigger，其中，Job 負(fù)責(zé)定義需要執(zhí)行的任務(wù)，Trigger 負(fù)責(zé)設(shè)置調(diào)度策略，Scheduler 將二者組裝在一起，并觸發(fā)任務(wù)開始執(zhí)行。Scheduler 可以通過SchedulerFactory來生成．

用spring封裝后的quartz更簡單，下面是一個具體的配置例子：

在其中job，用targetObject來指定任務(wù)類，可以 是任意的spring bean，targetMethod指定任務(wù)執(zhí)行的方法．Tigger一般用兩種，CronTriggerBean和 SimpleTriggerBean，一個triggerBean中可以配置多個job，一個Scheduler中可以配置多個trigger.
