SSM框架整合

环境

• IDEA
• MySQL 5.7.19
• Tomcat 9
• Maven 3.6

项目要求

• 数据库方面知识
• Spring，SpringMVC、 Mybatis，javaWeb
• H5，css，js，jquery，Bootstrap...

开始搭建项目

第一步:数据库

# 根据项目的要求创建数据库
# 完成相应的数据据库表的设计
# 插入相对应的数据
# 完成数据库

第二步:创建项目

使用IDEA创建Maven项目，并且添加Web支持

打开IDEA--->File-->New--->Project---->右侧的New Project--->选中Maven--->直接Next，不勾选Create from archetype--->填写项目的名字，以及项目的分组，版本号（非必要不填默认就好）

--->Finally完成之后---->选中项目右键Add Frameworks Support，添加web支持

第三步：导入依赖
