1.jar包
Spring的jar包；Mybatis的jar包；Mybatis与Spring整合包；数据库连接包；第三方连接池包。
2.需要配置的文件
SqlMapConfig.xml：Mybatis核心配置文件（主要交给Spring管理，并不需要什么配置，但必须存在）
db.properties：数据库连接配置，主要配置用户密码
applicationContext*.xml：Spring的核心配置，配置数据源、连接池、mapper扫描包位置、事务、service扫描。
（*表示可以将事务单独成一个配置，例如：applicationContext-dao.xml）
springmvc.xml：配置扫描注解包（可包括Spring配置中的service扫描包）、注解驱动（处理器的适配器和映射器配置）、视图解析器、自定义转换器
log4j.properties：日志配置
web.xml：前端配置

5.applicationContext*.xml
applicationContext-dao.xml：

classpath指定是文件路径。建议将约束都导入，方便配置。
applicationContext-trans.xml：

上面演示的是采用配置式，下面采用注解式：
1 <bean id="transactionManager" class=""org.springframework.jdbc.datasource.DataSourceTransactionManager> 2 <property name="dataSource" ref="dataSource"></property> 3 </bean> 4 <tx:annotation-driven transaction-manager="transactionManager"/>
