1、 Quartz 插件的使用Quartz 框架提供了几种用于扩展平台能力的方式。通过使用各种 钩子 (通常指的就是扩展点)，Quartz 变得很容易被扩展和定制化来适应你的需要。其中一个最简单的扩展框架的方法就是使用 Quartz 插件。本章就来看看如何使用插件机制让 Quartz 进入到之前 Quartz 用户没去过的领域。一、使用 Quartz 自带插件范例下面将使用插件实现从 XML 得到 JOB，不用手工的把 job 和 trigger 加到 Scheduler 中去再来运行，这样就很方便。如果要更改任务，直接在 xml 中配置就可以了。不用再写 Java代码。1、首先是 job 类：j
