解决方案：
1 <!-- 2. 使用扫描器将操作的接口扫描到 Spring 容器 --> 2 <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> 3 <!-- 使用会话工厂 --> 4 <property name="sqlSessionFactoryBeanName" ref="sqlSessionFactoryBean"></property> <!--修改为<property name="sqlSessionFactoryBeanName" value="sqlSessionFactoryBean">--> 5 <!-- 扫描的接口所在的包 --> 6 <property name="basePackage" value="cn.mgy.mapper"></property> 7 </bean>
