1、重庆正大软件学院软件系MVC框架程序设计电子教案重庆正大软件职业技术学院教案（项目类）授课对象系 别软件系本次课学时4学时年级班次大二章节题目第7章 项目编码目的要求（含技能要求）理解客户档案管理模块客户档案增删改查功能的业务流程理解客户档案管理模块客户档案增删改查功能的程序流程通过练习理解SSH的框架组件及运行流程本节重点理解SSH的框架组件及运行流程本节难点理解客户档案管理模块客户档案增删改查功能的业务流程教学方法项目教学法教学用具机房、屏幕广播问题引入通过第六章的详细设计文档，从而引出本次课程。难点与重点讲解方法引导、分析、讲解、实作演示本次课小结课程小结教后礼记讨论、思考题、作业（含实

2、训作业）完成本次课的课堂任务填写实验报告任务介绍（5分钟）根据需求分析和设计实现客户档案管理模块客户档案增加、修改、查询、删除功能。任务解析（50-60分钟）1. 客户档案表映射文件Client.hbm.xml编写2. 客户档案实体映射类Client编写3. 前台客户档案增删改查页面编写4. 后台业务控制器（action类）ClientAction编写5. 客户档案struts文件的配置6. 用dwr框架实现客户编号重复性验证的dwr.xml编写7. 后台业务处理层接口IClientService编写8. 后台业务处理层实现类ClientService编写9. 后台持久化层接口IClientD

3、ao编写10. 后台持久化层实现类ClientDao编写11. Spirng配置文件applicationContext_beans.xml的配置详细步骤1. 客户档案表映射文件Client.hbm.xml编写删除客户时应删除与此客户相关的所有的订货单和进货单信息，与订货单和进货单相关级联关系中cascade属性的配置应该是all-delete-orphan。关键代码如下：<hibernate-mapping><class name="com.zds.slms.domain.Client" table="client"><i
