NoUniqueBeanDefinitionException: No qualifying bean of type

NoUniqueBeanDefinitionException: No qualifying bean of type

在启动项目时报错，bean不是唯一

Caused by: org.springframework.beans.factory.NoUniqueBeanDefinitionException: No qualifying bean of type 'org.deyi.sc.dao.PathogenSeqMapper' available: expected single matching bean but found 2: pathogenSeqExtendMapper,pathogenSeqMapper

原因：当两个实现类一个注入父类，一个注入子类，spring就会报错不知道选择哪一个注入

PathogenSeqMapper seqDao;
PathogenSeqExtendMapper seqEDao;

解决方案：全部注入子类，启动成功！
