1、添加spring相关jar包
2、配置ehcache jar包。
3、添加ehcache mybatis 适配器jar包（在mybatis官网）
4、添加spring mybatis 适配器jar包（在mybatis）官网
5、pom.xml

<context:component-scan base-package="com.atguigu.mybatis">

<!-- 引入数据库的配置文件 -->

<!--

2、spring用来管理事务，spring声明式事务
-->
<!--创建出SqlSessionFactory对象 -->

<property name="dataSource" ref="dataSource"></property>
<!-- configLocation指定全局配置文件的位置 -->
<property name="configLocation" value="classpath:mybatis-config.xml"></property>
<!--mapperLocations: 指定mapper文件的位置-->
<property name="mapperLocations" value="classpath:mybatis/mapper/*.xml"></property>
</bean>
<!--配置一个可以进行批量执行的sqlSession -->
<bean id="sqlSession" class="org.mybatis.spring.SqlSessionTemplate">
<constructor-arg name="sqlSessionFactory" ref="sqlSessionFactoryBean"></constructor-arg>
<constructor-arg name="executorType" value="BATCH"></constructor-arg>
</bean>
<!-- 扫描所有的mapper接口的实现，让这些mapper能够自动注入；
base-package：指定mapper接口的包名
-->
<mybatis-spring:scan base-package="com.atguigu.mybatis.dao"/>
<!-- <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.atguigu.mybatis.dao"></property>
</bean> -->
</beans>
7、mybatis-config.xml
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
<settings>
<setting name="mapUnderscoreToCamelCase" value="true" />
<setting name="jdbcTypeForNull" value="NULL" />
<!--显式的指定每个我们需要更改的配置的值，即使他是默认的。防止版本更新带来的问题 -->
<setting name="cacheEnabled" value="true" />
<setting name="lazyLoadingEnabled" value="true" />
<setting name="aggressiveLazyLoading" value="false" />
</settings>
<databaseIdProvider type="DB_VENDOR">
<property name="MySQL" value="mysql" />
<property name="Oracle" value="oracle" />
<property name="SQL Server" value="sqlserver" />
</databaseIdProvider>
</configuration>
注意：此处mybatis配置文件中没有配置数据源，数据源由spring负责。
此外还需要ehcache.xml配置文件,Mapper.xml文件。
