Error creating bean with name报错

Unsatisfied dependency expressed through field 'mapper'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.grg.platform.pvac.attendance.mapper.AttendanceDailyMapper' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

解决方法：经检查代码中，controller、Service层以及Dao层分别都有@controller、@Service、@Dao注解以及@autowired注解，排除没有注解导致的问题，在启动类，添加 

@MapperScan("com.grg.platform.pvac.attendance.mapper") 

重新启动项目，问题解决。
