Nasıl org.springframework.beans.factory.BeanCreationException

Question

Nasıl bir Java Bahar MVC web uygulaması var. Ayrıca

public interface RESTClientService 
{ 
} 

ve yukarıdaki arayüzü uygulayan bir sınıfı:

@Controller 
@RequestMapping("module/car") 
public class CrentalCarController 
{ 
@Autowired 
@Qualifier("restClientService") 
private RESTClientService restClientService; 

//the remaining codes 
} 

şöyle Başka bir arayüze sahip: Şimdi şu kontrolör dersim var. Bu arabirim, başlangıçta belirtilen denetleyiciyi içeren projeye bağımlı olarak eklenen farklı bir projedir. Benim kontrolöre

@Autowired 
    @Qualifier("restClientService") 
    private RESTClientService restClientService; 

ekledikten sonra, ben konsolda aşağıdaki hatayı alıyorum:

Ben tam sorunu çözmek için kuramıyorum

, emin değilim Yanlış bir şey yapıyorsam İşte. Bu fasulye yerde eşlenmedi

Answer 1

com.smartwcm.commons.rest.RESTClientService .. ya yapılandırmalarınızın xml eklemek ya da belki denemek:

@Component 
public interface RESTClientService 
    { 
    } 

Eğer don also..if Aynı fasulyenin birden fazla deklarasyonuna sahipseniz, o zaman Qualifier ek açıklamalarına ihtiyacınız olmazdı. daha fazla bilgi için: http://www.tutorialspoint.com/spring/spring_qualifier_annotation.htm
