> ### 前言 ###

基于SSM的果蔬经营平台系统有两大用户角色：

用户：首页、商品信息、广告信息、个人中心、购物车。

管理员：用户管理、商品信息管理、类型管理、系统管理、订单管理。

> ### 前台功能模块 ###

在系统前台可以看到有首页、商品信息、广告信息、个人中心、购物车。

在首页，我们可以看到有商品信息推荐、广告信息推荐等显示。![fbdf23be56504bf08a405791a8a27884.png][]

在个人中心，用户登录后可以在这里进行修改自己的信息和上传自己的头像信息，或者查看自己的订单、地址、收藏等信息。![a16700d223244dfda549a0ccab90214b.png][]

如需要购买商品而金额不够可以点击充值进行充值。![2f7852bdc41e4085bfc98e99229ceb58.png][]

添加地址页面，用户购买商品需要填写地址并且选择地址。![57837813a5ac4f149fad94c6593e88e6.png][]
