沒有合格的bean類型AbstractRepository <?>'可用：期望的單個匹配bean，但找到2

Question

我正在使用spring-boot來實現一些其他端點。我用@Autowired實現了AbstractRepository和AbstractEnpoint。然後兩者都被真正的2個端點擴展：ClientEndpoint和HospitalReservationListEndpoint。 但我得到在瀏覽器中出現以下錯誤，當我嘗試調用端點是neccessite庫方法：

"org.springframework.beans.factory.NoUniqueBeanDefinitionException: No qualifying bean of type 'org.parcaune.reservationmanagerservices.core.AbstractRepository<?>' available: expected single matching bean but found 2: clientRepository,hospitalReservationListRepository"

我的課表：

我AbstractRepository

/* 
@NoRepositoryBean 
Annotation to exclude repository interfaces from being picked up 
and thus in consequence getting an instance being created 
*/ 

@NoRepositoryBean 
public interface AbstractRepository<T> extends JpaRepository<T, String> 
{ 
} 

我AbstractEndpoint

public abstract class AbstractEndpoint<T> { 

    @Autowired 
    protected AbstractRepository<T> repository; 

    @GET 
    @Path("/ping") 
    @Produces(MediaType.TEXT_PLAIN) 
    public String ping() { 
    return "Endpoint works!"; 
    } 

    @GET 
    @Produces(MediaType.APPLICATION_JSON) 
    public List<T> getAll() { 
    List<T> list = new ArrayList<>(); 
    list = repository.findAll(); 
    return list; 
    } 
} 

我的客戶端類：

public interface ClientRepository extends AbstractRepository<Client> { 
} 

和

@Component 
@Path("/clients") 
public class ClientEndpoint extends AbstractEndpoint<Client> { 
} 

我的醫院 - 類

public interface HospitalReservationListRepository extends 
AbstractRepository<HospitalReservationList> { 
} 

和

@Component 
@Path("/hospitalreservationlist") 
public class HospitalReservationListEndpoint extends 
AbstractEndpoint<HospitalReservationList> { 
} 

Answer 1

最簡單的方法是將倉庫添加爲通用參數如下：

public abstract class AbstractEndpoint<T,R extends AbstractRepository<T>> { 

    @Autowired 
    protected R repository; 

... 

我希望有更好的方法來做到這一點，如果你能找到一個請在這裏評論。
