【郑州校区】品优购电商系统开发第 1 章分布式框架-Dubbox 四
4.品优购-框架搭建
4.1 工程结构分析与设计
最终完整的工程结构如下：
工程说明：
pinyougou-parent 聚合工程
pinyougou-pojo 通用实体类层
pinyougou-dao 通用数据访问层
pinyougou-xxxxx-interface 某服务层接口
pinyougou-xxxxx-service 某服务层实现
pinyougou-xxxxx-web 某 web 工程
4.2 创建数据库表
执行资源文件夹中 pinyougou-db.sql
4.3 搭建框架
4.3.1 父工程
创建 Maven 工程 pinyougou-parent （POM） ，groupId 为 com.pinyougou ,artifactId 为pinyougou-parent , 在 pom.xml 中 添 加 锁 定 版 本 信 息 dependencyManagement 与
pluginManagement，详见“资源/配置文件/第一天搭建/父工程/pom.xml”。
以下模块均继承自此父工程
4.3.2 通用实体类模块
创建通用实体类模块-pinyougou-pojo
4.3.3 通用数据访问模块
创建通用数据访问模块 pinyougou-dao .添加依赖 Mybatis 和 pinyougou-pojo

4.3.8 商家管理后台
构建 web 模块 pinyougou-shop-web 与运营商管理后台的构建方式类似。区别：
（1）定义 tomcat 的启动端口为 9102
（2）springmvc.xml

4.4 实体类与数据访问层模块
4.4.1 生成代码
利用反向工程 generatorSqlmapCustom 实现实体类与数据访问层代码的自动生成
4.4.2 拷贝代码
将 com.pinyougou.pojo 包拷贝到 pojo 工程
将 com.pinyougou.mapper 包和 resouce 下的 com.pinyougou.mapper 文件夹拷贝到 dao 工程
4.4.3 修改实体类代码
修改每个实体类，让其实现 Serializable 接口
