技术栈

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

使用说明

  1. 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 用户账号/密码： user/123456 管理员账号/密码：admin/admin
