srsnew's Introduction

SRS

1 认真阅读《begining java object:从概念到代码》第9、10、11、14、15、16章(尤其是第14章)

已通读《begining java object:从概念到代码》整本书,对List、Map、Set等几种对象集合有了透彻的认识,对继承、封装、多态有了更加深刻的认识,学会了如何面向接口编程,降低代码间的耦合。

2使用OOA&D构建SRS系统。

整体文件结构 本Github运用面向对象的方式,并采用Struts2+Hibernate+Spring4的方式进行整合开发,构建了选课SRS系统。

3根据书中示例类图(P430)构建系统领域模型并实现测试 测试

4使用(PD或visio)画出你所实现的系统领域类图和至少两个关键场景的顺序图。

###领域类图 领域类图 ###关键顺序图 ###选课 选课 ###显示课时计划 显示课时计划

5采用三层结构实现基于web的SRS系统,后台采用sqlite为数据存储

SQLite Mysql 三层结构分别为数据访问层com.eric.SRS.dao(com.eric.SRS.dao.impl),领域逻辑层com.eric.SRS.model\com.eric.SRS.service(com.eric.SRS.service.impl),表示层com.eric.SRS.action。数据访问层采用Hibernate,利用Spring统一托管,动态加载properties数据,通过加载sqlite转换文件可以实现mysql、sqlite之间的任意切换。

6 可以采用guitar销售V3的系统架构也可以自行选择,但要求业务逻辑主要由model完成,数据源可切换

model service 业务逻辑依托model层,通过model和service形成领域逻辑层。数据访问层采用Hibernate,动态加载properties数据,可以实现mysql、sqlite之间的任意切换。

7 数据结构请根据需要持久化的对象进行设计,给出数据库结构(表)的截图。 database 数据结构通过Hibernate注解标注model实体类,实现了类与数据的分离,借助ORM工具持久化类。

8至少需要实现的功能:学生登录、课程查询并选课(模型实现选课逻辑),课程、教师增删查改,学生成绩查询,课程选课情况查询(哪些人选了) ###登陆 database ###教师增删查改 database ###学生选课 database
