简介:Java领域优质创作者、Java项目、学习资料、技术互助
文末获取源码
基于SpringBoot+Vue的网上书城系统(前后端分离项目)
本项目分为前后台,前台为普通用户登录,后台为管理员登录;
角色:管理员、用户
功能:首页推荐(默认根据用户买过的商品进行推荐,如果没买过则根据商品销量推荐)、轮播图管理、商品、订单、购物车、商品评论、商品评论点赞、商品收藏、商品点赞、订单支付、公告、权限控制等。
使用人群:
正在做毕设的学生,或者需要项目实战练习的Java学习者
由于本程序规模不大,可供课程设计,毕业设计学习演示之用
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.硬件环境:windows 7/8/10 1G内存以上;或者 Mac OS;
4.数据库:MySql 5.7/8.0版本均可;
5.是否Maven项目:是;
6.是否为前后端分离项目:是
后台: SpringBoot + Mybatis-plus + Mybatis + lombok插件
前台:Vue + Vue Router + ELementUI + Axios
**先启动后端再启动前端**
后端:
1. 使用Navicat或者其它工具,在mysql中创建对应sql文件名称的数据库,并导入项目的sql文件;
2. 使用IDEA/Eclipse/MyEclipse导入后端项目end文件夹,导入成功后请执行maven clean;maven install命令,然后运行;
3. 将项目中application.yml配置文件中的数据库配置改为自己的配置;
4. 运行项目,后端运行成功后再运行前端项目;
前端:
1、确保安装好node及npm,命令行切换到front所在路径
2、执行npm run serve启动项目
后台地址:http://localhost:8001/login
