How to configure multiple scan paths in mybatis

Baidu got it, but it’s very messy. Let’s sort it out a little:

Recently dismantled the project and encountered a small problem. I’ll record it a little bit:

<!-- spring和MyBatis完美整合，不需要mybatis的配置映射文件 -->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <!-- 自动扫描mapping.xml文件 -->
        <property name="mapperLocations" value="classpath*:com/**/mapping/*.xml"></property>
    </bean>
 
    <!-- DAO接口所在包名，Spring会自动查找其下的类 -->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.xxx.dao" />
        <!--<property name="basePackage" value="com.xxx.dao,com.yyyy.dao" />-->
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>
    </bean>
