请教:springmvc+mybatis整合,启动报错:报错信息如下:

  <!-- 1. 数据源  -->
    <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
        <property name="driverClassName" value="${driver}"/>
        <property name="url" value="${url}"/>
        <property name="username" value="${username}"/>
        <property name="password" value="${password}"/>
    </bean>

    <!-- mybatis和spring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,省去configuration.xml手工配置 -->
        <property name="mapperLocations" value="classpath*:mapper/*.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="dao"/>
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>
    </bean>

    <!-- (事务管理)transaction manager, use JtaTransactionManager for global tx -->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource"/>
    </bean>

    <tx:annotation-driven transaction-manager="transactionManager"/>

这个问题,你看最终的提示是:
NoSuchBeanDefinitionException: No qualifying bean of type [com.fh.dao.UsysparamMapper]

没有这样的 bean 定义异常,这个时候你应该看 MapperScannerConfigurer 这个 bean 对象的 basePackage属性,看它的value值范围是否写对和
spring 组件扫描范围是否写对。
