简介： 实战SSM_O2O商铺_02数据模型设计及实体类的创建

20191208102256370.png

模块介绍

主要分为3个大模块

  • 前端展示模块

  • 店家模块


20180514040304976.png

  • 后台管理模块

建立o2o数据库（MySql）

数据模型及对象设计

总览

根据上述划分的功能模块，设计出主要的实体类（10个）以及实体类对应的表（10个）

下面来拆分逐个解析，创建实体类和库表

区域

分析


20180514051301588.png



主要属性:

  • areaId
  • areaName
  • priority (权重,数值越大页面展示越靠前)
  • createTime
  • lastEditTime


实体类

/src/main/java新建包com.artisan.o2o.entity，新建Area.java

/**

微信账号与本地账号

分析


这两个表与实体类的设计，要通过外键用户ID与对应的用户建立联系 ，这样才能确定是哪个用户。
