我相信您配置错误basePackage。MapperScannerConfigurer它应该是包含映射器类而不是映射器类本身的包。所以尝试将其更改basePackage为：<bean id="mapperSpeaker" class="org.mybatis.spring.mapper.MapperScannerConfigurer">&nbsp; &nbsp; <property name="basePackage" value="ph.com.aub.mapper" />&nbsp; &nbsp; <property name="sqlSessionFactoryBeanName" value="sqlSessionFactorySpeaker" /></bean>
