Note: When defining two MapperScannerConfigurers, make sure that the two mapping dao interfaces cannot be in the same package. Otherwise, the exception that the second dao interface method cannot be found will occur.
<!-- Define MapperScannerConfigurer 1 -->
<bean id="f" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="sqlSessionFactoryBeanName" value="f_ssf"></property>
<property name="basePackage" value="**"></property>
</bean>
<!-- Define MapperScannerConfigurer 2 -->

<property name="sqlSessionFactoryBeanName" value="s_ssf"></property>
<property name="basePackage" value="**"></property>
