Castle是针对.NET平台的一个开源项目,从数据访问框架ORM到IOC容器,再到WEB层的MVC框架、AOP,基本包括了整个开发过程中的所有东西,为我们快速的构建企业级的应用程序提供了很好的服务.具体可参看TerryLee的Castle 开发系列文章。      可以通过称为 Facility 的组件用控制反转 (Inversion of Control, IoC) 和依赖注入将 第三方组件插入内核中。Startable Facility当一个组件满足一定的依赖关系之后,让它自动运行,比如说启动一个窗体或者启动某种服务。 Startable Facility的使用可以说是非常地简单,只要我们的组件实现了IStartable接口就可以了,关于Startable Facility具体可参看Castle IOC容器实践之Startable Facility(一)Castle IOC容器实践之Startable Facility(二)。Quartz 是一个要与 Castle集成的大项目,因为它仅需要您用 Castle的生命周期来启动和停止它。这意味着,当 Castle启动时,您想要 Quartz 启动,当 Castle关闭时,您想要 Quartz 停止。

为了保持本示例的简单性,Quartz 配置使用 Quartz 发行版附带的默认值。这些默认值位于 quartz.properties 文件中,该文件是 dll 文件的一部分。要配置 Quartz 以将数据库用于持久层、远程调度和其他高级选项,必须创建自定义的 quartz.properties 文件。

Quartz 调度器易于启动和关闭;它只通过调用 StdSchedulerFactory.DefaultScheduler 来检索调度器对象。要启动 Quartz,执行 Scheduler.Start() 方法。要停止 Quartz,执行 Scheduler.Shutdown() 方法。要使 Quartz 的生命周期跟随 Castle,将 Start() 调用放入 IStartable的 Start() 方法中,并将 Shutdown() 调用放入 IStartable的 Stop() 方法中。清单 3 展示了添加 Quartz 代码之后完整的实现。
