本文介绍了SSM框架的整合思路，包括持久层、业务层、表现层的配置文件及相关组件，如数据源、事务、包扫描器等。还阐述了开发步骤，如创建数据库和web工程、添加jar包、开发各层代码等，最后给出了相关配置文件和码云链接。

1.整合思路：
持久层
sqlMapConfig.xml(可以为空、可以不存在)
applicationContext-dao.xml
数据源
sqlSessionFactory
数据源
别名
mapper扫描器
业务层
applicationContext-service.xml
事务
包扫描器 @Service
表现层
springmvc.xml
包扫描器 @Controller
注解驱动 <mvc:annotation-driven/>
视图解析器
web.xml
前端控制器：初始化springmvc容器
监听器：初始化spring容器

2、开发步骤
创建数据库
创建web工程
添加jar：mybatis、mybatis扩展包、spring、mybatis和spring整合包、junit、springmvc
添加配置文件
持久层开发：代码使用逆向工程
业务层开发：接口+实现类
表现层开发：注解开发方式
