工厂模式辨析与应用研究

通过使用工厂模式封装了易变对象,屏蔽了客户需求变化的负面影响,解决了客户和具体对象的紧耦合。本文讨论工厂模式中简单工厂模式、工厂方法模式和抽象工厂模式的基本结构,并对其适用场景和优缺点进行深入剖析。为进一步降低客户对工厂对象的依赖,用.NET中的反射机制和配置文件动态地创建工厂对象。

Analysis and Applied Research on Factory Patterns

By the factory patterns,the volatile objects are sealed,negative impacts of changeable customer needs are shielded,and the problem of tightly coupling between customers and concrete objects is resolved.The basic structures of simple factory pattern,factory method and abstract factory pattern in the factory patterns are discussed.In-depth analysis on its applicability to scenes and advantage and weakness is also conducted.To further reduce customers' reliance on factory objects,factory objects are dynamicall...
