配置文件如下:
base-context.xml文件如下:

db-mybatis.xml如下:

在mappers下边是mybatis的xml文件,启动的时候出现错误:
DEBUG o.m.spring.SqlSessionFactoryBean - Property 'configLocation' not specified, using default MyBatis Configuration
解决方式如下:
<bean id="sessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="dataSource"/> <property name="mapperLocations" value="classpath:mybatis/mappers/*.xml"/><property name="configLocation" value="classpath:spring/persistence-context.xml"/> </bean>
在sessionFactory下加入:
<property name="configLocation" value="classpath:spring/persistence-context.xml"/>
添加persistence-context.xml
的位置即可,或者所有的文件都在一个文件即可
