在搭建ssm框架的过程中，出现了如上很奇怪的错，在测试dao层的时候没有问题，但是就是在service找不到dao的实例，自动注入失败，刚开始以为是注解的问题，更换注解，加上名字也不管用，后来在一篇博客里面找到了类似的错，说是dao的接口扫描路径的问题，我就按他的方法加了一层路径，结果就好了，可是我仔细检查了也没有发现我的路径有啥问题，猜测可能实在部署到tomcat的时候多生成了一层路径。

原来的配置是这样的：

<!-- 配置dao接口扫描 -->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="cn.tedu.store.mapper" />
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>

    </bean> 

修改后的配置是这样的：

<!-- 配置dao接口扫描 -->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="cn.tedu.store.mapper;cn.tedu.store.*.mapper" />
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>

    </bean> 

然后就能正常运行了，我的项目目录如图：
