因为SpringMVC是Spring框架的一个模块,所以不存在SpringMVC和Spring的整合,所以实际是SpringMVC+Mybatis和Spring+Mybatis
所以分成以下步骤
- JAR包
- 大概是这几个包,包括了Spring,SpringMVC,Mybatis,Mysql驱动,以及它们之间的中间包
- 框架所需配置文件
- db.properties(把连接数据库的配置配置信息外置)
-
applicationContext.xml(Springpei'配置文件)jdbc.driver=com.mysql.jdbc.Driver jdbc.url=jdbc:mysql://localhost:3306/mybatis jdbc.username=root jdbc.password=123456789zap jdbc.maxTotal=30 jdbc.maxIdle=10 jdbc.initialSize=5

创建po,dao(接口和xml,用mapper接口所以不用接口实现类)service,controller包
