[org.mybatis.spring.mapper.ClassPathMapperScanner]-No MyBatis mapper was found in '[com.xxx.xxx.dao]

项目启动后，控制台输出中有以下内容：

[org.mybatis.spring.mapper.ClassPathMapperScanner]-No MyBatis mapper was found in '[com.xxx.xxx.dao]' package. Please check your configuration.

这是因为 spring-mybatis.xml 配置文件中多了以下：

	<!-- 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.xxx.dao" />
		<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>
	</bean>
	 -->
