--------------------

> ### 前言 ###

基于springboot在线外卖系统有三大角色：

用户：首页、商家、菜品信息、公告资讯、个人中心、后台管理、购物车

商家：首页、个人中心、菜品信息管理、留言备注管理、订单管理。

管理员：首页、个人中心、商家管理、用户管理、菜品分类管理、菜品信息管理、留言备注管理、系统管理。

> ### 用户前台 ###

用户登录页面，如果没有账号的用户可以点击注册输入相关信息进行注册并且返回登录页面。

进入前台可以看到有首页、商家、菜品信息、公告资讯、个人中心、后台管理、购物车等功能。![0587d3b74d854065a921440ed420af20.png][]

在个人中心可以查看自己的信息并且修改。![9382b3f5ab5a47daa152d0df4807556b.png][]

用户下单外卖需要有一定的金额，金额不足可以选择充值金额。![de4b1ddcd01c440488bea838d69f0256.png][]

用户下单，也是需要填写地址的。![b19ddc3f30264daf99f1367df71a6b8c.png][]

公告资讯可以查看管理员发布的信息。![e26fa02fb6604f44bd472a33646f6344.png][]

菜品信息显示，用户可以根据自己喜欢的菜品进行下单。![f914d39ff8fc4770a4f60807ec661a5f.png][]

选择自己喜欢的菜品点击后可以查看菜品的详情信息。![ca464a4131e94caf92983d20c62e3531.png][]

> ### 商家功能 ###

管理员和商家登录页面。

![6c6733781c0a4d58a81f72b8ebe7c046.png][]商家登录后可以看到有首页、个人中心、菜品信息管理、留言备注管理、订单管理。

在菜品信息中， 商家可以发布新的菜品。 ![67d8464711564d05b3dba67f83bb169b.png][]

在订单管理中可以查看用户下单的订单、完成的订单、未支付的订单、已取消的订单、已支付的订单。![49bcad03b31643c88d402dec0e27c89b.png][]

> ### 管理员功能 ###

管理员进入系统有首页、个人中心、商家管理、用户管理、菜品分类管理、菜品信息管理、留言备注管理、系统管理。

在商家管理中，管理员可以申请商家申请的注册信息账号，审核通过后才能登录系统。![5e492ddbd7d044fd86980ead9469665a.png][]

用户管理中管理员可以管理用户的信息。
