一、开发环境准备

• JDK1.8
• MySQL8
• idea2021
• Tomcat8.5.87

二、搭建SSM

2.1新建Maven项目

【File】-> 【new Project】-> 【选择Archetype】

2.2项目整体结构

项目的整体结构： 包括resources目录下的xml和webapp目录下文件。如果不包含某些文件，就自己创建。

MVC结构、spring-config.xml（applicationContext.xml）、jdbc.properties（数据源）、mybatis-config.xml（mybatis配置类）、spring-mvc.xml（springMVC前端控制器配置类）、web.xml（web项目配置类）
