SpringBoot：No qualifying bean of type 'com.xxxx.dao.DailyMapper' available: expected at least 1问题的解决

异常代码：

    No qualifying bean of type 'com.xxxx.dao.DailyMapper' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {}

如图：

 

原因：

Spring boot Application没有扫描到mapper

 

解决办法：

主要看框架是用什么方法配置的，楼主是SpringBoot +Mybaits，仓库配置加上@MapperScan(annotationClass = Repository.class, basePackages = "com.xxx.dao"）

注意上面红字部分，因为DataConfig中有此注解，要求所有mapper接口也要加此注释，否则扫描不到，即：

@Repository

pulic interface DailyMapper{

//....省略

}
