Spring+MyBatis+Struts2整合
框架环境:
Spring 3.0.5 MyBatis 3.0.4(ibatis已正式更名为MyBatis) Struts2
MyBatis代码生成：mybatis-generator-core-1.3.1.jar
我是按照三个框架的整合步骤来做的。Spring+MyBatis+Struts2整合与传统的SSH框架不同的区别就在于把Spring和Hibernate的整合换成Spring+MyBatis。
代码层级的变动就是DAO层级以及实现的变更。

第一步:
新建Web工程，加入jar包。
第二部：
配置Web.xml 加入Struts2 和Spring Listener
