org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'com.hzy.spboo.dao.AreaDaoTest': Unsatisfied dependency expressed through field 'areaDao'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.hzy.spboo.dao.AreaDao' available: expected at least 1 bean which qualifies as autowire candidate.
