    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:
