技术栈
- 后端：servlet 2. 前端：JSP+css+javascript
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news.properties配置文件中的数据库配置改为自己的配置; 4. 运行项目，在浏览器中输入http://localhost:8080/News 后台地址:http://localhost:8080/News/user?action=login 用户名:admin,密码:123456
