해결방법 

@Primary 

동일한 타입의 빈이 여러 개 등록되어 있을 때, 우선적으로 주입되는 빈을 지정하는 방법

 

 

예시 

@Component
@Primary
public class PrimaryComponent implements MyInterface {
    // ...
}

@Component
public class SecondaryComponent implements MyInterface {
    // ...
}

@Service
public class MyService {
    @Autowired
    private MyInterface myInterface;

    // ...
}
