设计模式在实际业务应用中的介绍之2——业务工厂
在C#中实现的基于工厂模式打造的业务应用案，全部都是干货。
以前一直没有想过写一些东西来把项目中用到的知识点及技术实现做一个归纳整理并分享出来。现在打算逐渐的把项目中的一些东西整理并分享出来，与大家共勉！
工厂模式相比大家都比较清楚了，现在就该模式在实际项目中的应用做一个实例分享。
工厂模式的核心点就是可以依据应用自由组装业务实现，灵活的适应业务变更，极大的增强系统对业务变更的应变能力。
下面就拿实际项目WMS中的一个模块仓库管理来与大家分享，先简单描述下实现思路：
根据需求分析将仓库管理模块进行业务建模，然后抽象出该模块应该具备的功能，
根据抽象结果分别创建该模块的抽象业务类Warehousebiz及该类的实现类Warehousebiz。
1、先看看结构图：
2、定义业务抽象类Warehousebiz,根据业务抽象该模块的应有功能，下面节选4个功能来介绍
1)获取数据库仓库GetWarehouses
2)获取数据库仓库货架GetStorage_racks
3)获取数据库仓库货架区域GetStorage_rack_zones
4)获取绑定记录GetPack_bindingPager

4、定义普通业务工厂类BizFactoryWarehouse，负责装配业务类

6、定义AOP模式工厂类AOPFactory，负责横切（也有的叫劫持）业务类
