模块介绍

主要分为3个大模块

前端展示模块

这里写图片描述

店家模块

这里写图片描述

后台管理模块

这里写图片描述

建立o2o数据库（MySql）

这里写图片描述

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）

这里写图片描述

下面来拆分逐个解析，创建实体类和库表

区域

分析

这里写图片描述

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

package com.artisan.o2o.entity;

import java.util.Date;

/**
 * 
 * 
 * @ClassName: Area
 * 
 * @Description: 区域实体列,对应数据库中的tb_area.属性采用引用类型(Integer\Long等),
 *               不建议使用基本类型(基本类型有默认值) ,以免mybatis动态sql出现莫名其妙的问题

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。
