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；查看源码目录中是否包含pom.xml；若包含，则为maven项目，否则为非maven项目

技术栈

1. 后端：servlet
2. 前端：JSP+css+javascript

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news.properties配置文件中的数据库配置改为自己的配置;

@RequestMapping("CategoryServlet")
public class CategoryController {
    @Autowired
    private HttpServletRequest request;
    private CategoryDao categoryDao=new CategoryDao();

    @RequestMapping("/listforadmin")
    public String listforadmin(){
