找不到符合依赖项错误的bean

Question

我正在使用spring开发一个程序，我面临着这个问题，它说：

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean found for dependency [com.owlexa.cms.dao.MemberProductDao]: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

根据我的观察，问题出在我的服务/服务实施中

服务：

public interface MemberService {

Member findMemberByPK(Integer id);
void deleteMember(Member obj);
void saveOrUpdateMember(Member obj);
Page<Member> findMemberListing(MemberSearchParams params, Pageable pageable);
Member findMemberByColsAndValues(String[] cols, Object[] values);

/*MemberProduct*/
Page<MemberProduct> findMemberProductListing(MemberProductSearchParams params, Pageable pageable);
MemberProduct findMemberProductByColsAndValues(String[] cols, Object[] values);
}

和我的ServiceImpl

@Service
@Transactional(readOnly = true)
public class MemberServiceImpl implements MemberService{

    @Autowired
    MemberDao memberDao;

    @Autowired
    MemberProductDao memberProductDao;

    MemberSearchParams memberParams = null;

    MemberProductSearchParams memberProductParams = null;

    @Override
    public Member findMemberByPK(Integer id) {
        return memberDao.findOne(id);
    }

    @Override
    @Transactional
    public void deleteMember(Member obj) {
        memberDao.delete(obj);
    }

    @Override
    @Transactional
    public void saveOrUpdateMember(Member obj) {
        memberDao.save(obj);
    }

    @Override
    public Page<Member> findMemberListing(MemberSearchParams params, Pageable pageable) {
        return memberDao.findListing(params, pageable);
    }

    public Member findMemberByColsAndValues(String[] cols, Object[] values) {
        memberParams = new MemberSearchParams();
        memberParams.setEqColumns(cols);
        memberParams.setEqValues(values);

        Page<Member> member = memberDao.findListing(memberParams, null);

        if(member != null && !member.getContent().isEmpty()){
            return member.getContent().get(0);
        }

        return null;
    }

    @Override
    public Page<MemberProduct> findMemberProductListing(MemberProductSearchParams params, Pageable pageable) {
        return memberProductDao.findListing(params, pageable);
    }

    @Override
    public MemberProduct findMemberProductByColsAndValues(String[] cols, Object[] values) {

        memberParams = new MemberSearchParams();
        memberParams.setEqColumns(cols);
        memberParams.setEqValues(values);

        Page<MemberProduct> memberProduct = memberProductDao.findListing(memberProductParams, null);

        if(memberProduct != null && !memberProduct.getContent().isEmpty()){
            return memberProduct.getContent().get(0);
        }

        return null;
    }
}

请帮助我解决问题，并提供您的解决方案，thx提前。

我相信MemberProductDAO中至少有一个自动连接字段不是由Spring生成的。请共享您的MemberProductDAO文件和Spring。xml文件来调试更多。
