亦余心之所善兮，虽九死其犹未悔。这篇文章主要讲述解决spring mybatis 整合后mapper接口注入失败相关的知识，希望能为你提供帮助。
spring整合mybatis，在dao层我们只写一个接口，配置相应的*mapper.xml文件，

起始这是由于一个低级错误引起的，在applicationContext.xml中有如下的配置：

1 < bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> 2< property name="basePackage" value="https://www.songbingjia.com/android/com.xxx.xxx.dao.**.*" /> 3< property name="sqlSessionFactoryBeanName" value="https://www.songbingjia.com/android/sqlSessionFactory" /> 4 < /bean>

basePackage的value应该是指定包名，而我指定的文件名。
改成如下配置，编译正常通过：

1 < bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> 2< property name="basePackage" value="https://www.songbingjia.com/android/com.xxx.xxx.dao" /> 3< property name="sqlSessionFactoryBeanName" value="https://www.songbingjia.com/android/sqlSessionFactory" /> 4 < /bean>
