【如需全文请按文末获取联系】

一、项目简介

微信食堂线上订餐小程序可以实现商品管理，商品评价管理，商家管理，公告管理，商品订单管理，在线充值等功能。该系统采用了SSM框架，Mysql数据库，Java语言等技术实现管理员后台，采用微信开发者工具来对用户小程序端进行了开发。

二、系统设计

2.1软件功能模块设计

图4.1即为设计的管理员功能结构，管理员权限操作的功能包括对用户注册信息，对商家信息，商品信息，公告信息等进行管理。

图4.2即为设计的商家功能结构，商家权限操作的功能包括管理商品，管理并回复商品评价，管理商品订单，查看公告等。

图4.3即为设计的用户功能结构，用户权限操作的功能包括购买商品，查看商家资料，查看公告，查看商品评价，管理商品订单，进行账户充值等。

2.2数据库设计

（1）图4.4即为商品这个实体所拥有的属性值。

（2）图4.5即为商品订单这个实体所拥有的属性值。

（4）图4.7即为商家这个实体所拥有的属性值。

（5）图4.8即为上面介绍的实体中存在的联系。

三、系统项目部分截图

3.1管理员功能实现

商家管理
图5.2 即为编码实现的商家管理界面，管理员在商家管理界面中具备更改商家营业执照，商家星级类型以及商家联系方式等信息，以及删除，添加商家等权限。

用户管理
图5.3 即为编码实现的用户管理界面，管理员在用户管理界面为用户的账号进行密码重置，更改用户的基础信息，删除需要删除的用户资料等。

3.2商家功能实现

商品管理
图5.4 即为编码实现的商品管理界面，商家在商品管理界面中具备增加商品库存，减少商品库存，为商品进行下架，更改商品信息，添加商品等权限。

商品评价管理
图5.5 即为编码实现的商品评价管理界面，商家在商品评价管理界面中查看用户对订单商品的评价，商家需要回复评价信息。

3.3用户功能实现

商品信息
图5.7 即为编码实现的商品信息界面，用户在商品信息界面中购买商品，或点击加入购物车按钮把商品保存在购物车里面。

订单确认
图5.8 即为编码实现的订单确认界面，用户在订单确认界面中需要确认购买的商品以及收货的地址信息，在余额充足的情况下就可以成功支付订单。

我的商品订单
图5.9 即为编码实现的我的商品订单界面，用户在我的商品订单界面中可以取餐，可以退款，可以评价订单。
