摘　　要：组件的多样性使得不同类型组件的集成及管理变得十分复杂。通过分析不同类型组件的特征,采用了一种新的方式对组件进行了重新设计及封装,使得应用程序能够以统一、高效的方式访问组件。同时,引入了一套支持IOC的轻量级元数据引擎对组件的生命周期进行管理,使组件的配置和应用相分离,从而使组件的添加、修改、删除更加简单。在设计过程中运用了多种设计模式,使整个容器更加合理。The diversity of components makes it a tough work to integrate different kinds of components and manage them in a uniform way. Through analyzing the component＇s attributes of different kinds, a new method is adopted to redesign and encapsulate the component, which enables the application to access the components in a uniform and efficient way. Besides, asuitoflight-weightedmetadataengine, which provides IOC support, is introduced into manage the component＇ s life cycle which has decoupled the component＇ s configuration and application, simplified the process of the component＇ s creation, update and delete. To make the whole container more reasonable, lots of design patterns is applied during the design process.
