篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Spring MVC Spring MyBatis 整合 - 快速上手相关的知识，希望对你有一定的参考价值。
我个人比较喜欢写注释，在工作中对注释的重要性看的也比较高，所以大部分文字都在注释中，代码外的文字会写的偏少，关键能懂就行
先看一下整合后的工程目录（单工程，多工程以后会采用maven）
5个package分别对应 action, entity, mapper（也就是DAO，采用动态代理）, service, service 实现类
resources 下 相关资源文件：
db.properties: 数据库连接参数
log4j.properties： 日志
applicationContext-dao.xml： spring 和 mybatis 整合的一些配置（sqlSessionFactory，mapper 配置）
applicationContext-service.xml： 业务
applicationContext.xml： spring 核心配置文件（配置一些公用的内容，比如数据源，事务）
springmvc.xml： springmvc 全局配置文件
SqlMapConfig.xml： mybatis 全局配置文件
webapp结构简单就不多说了
下面先贴出maven的pom内容：
