功能说明

基于javaweb的SSM个人pc电脑商城系统(java+ssm+jsp+jquery+mysql)

项目介绍

该项目为前后台项目，分为普通用户与管理员两种角色，前台普通用户登录，后台管理员登录；

管理员角色包含以下功能：管理员登录,用户管理,一级分类管理,二级分类管理,商品管理,所有订单管理,留言管理,公告管理等功能。

用户角色包含以下功能：浏览所有商品,加入购物车,查看留言板和公告,查看我的订单,用户注册登录,提交订单,确认订单等功能。

环境需要

1.运行环境：最好是java jdk 1.8，我们在这个平台上运行的。其他版本理论上也可以。 2.IDE环境：IDEA，Eclipse,Myeclipse都可以。推荐IDEA; 3.tomcat环境：Tomcat 7.x,8.x,9.x版本均可 4.硬件环境：windows 7/8/10 1G内存以上；或者 Mac OS； 5.数据库：MySql 5.7版本； 6.是否Maven项目：否；

技术栈

后端：Spring+SpringMVC+Mybatis 2. 前端：JSP+jQuery+Ajax

使用说明

使用Navicat或者其它工具，在mysql中创建对应名称的数据库，并导入项目的sql文件； 2. 使用IDEA/Eclipse/MyEclipse导入项目，Eclipse/MyEclipse导入时，若为maven项目请选择maven; 若为maven项目，导入成功后请执行maven clean;maven install命令，然后运行； 3. 将项目中jdbc.properties配置文件中的数据库配置改为自己的配置; 4. 运行项目，输入localhost:8080/ 登录
