SSM整合仿小米商城后台（一）------基础配置

一、SSM整合思路

导入所有jar包
添加所有的配置文件
在web.xml文件中注册springmvc和spring框架
使用Mybatis的逆向工程自动生成实体类pojo,生成Mapper接口和Mapper.xml文件
新建service接口和实现类
新建controller
添加页面，图片，css
整改html页面为jsp页面
测试功能

二、实例

新建一个项目XiaoMi_background,导入jar包并配置
在项目目录下新建一个包config，在里面添加配置文件并将其转为资源文件夹

转为资源文件夹
在这里插入图片描述 jdbc.properties

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/xiaomissm?characterEncoding=utf-8
jdbc.username=root
jdbc.password=123456
