@Service 어노테이션을 붙였는데 에러가 난다면?
- spring mvc 에서 분명 어노테이션들을 Controller나 Service 에 잘 등록을 시켰는데 하단에 보이는 에러메시지 처럼 에러가 난다면.. 상당히 애를 먹을 것입니다.
(나는 분명 Service 를 등록하고 Service 인터페이스를 상속 받았는데 말이죠..)

1. 에러 문제 분석
WARN : org.springframework.web.context.support.XmlWebApplicationContext - Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'kakaoLoginTestComtoller': Unsatisfied dependency expressed through field 'ks'; nested exception is org.springframework.beans.factory.NoUniqueBeanDefinitionException: No qualifying bean of type 'com.care.root.KakaoLoginService' available: expected single matching bean but found 2: kakaoLoginServiceImpl,kakaoLoginService
문제는 빨간색으로 밑줄 친 부분에서 @Autowired 받는 Service 가 2개를 인식하고 있다 그것을 해결해라
라고 예상을 하게 되었습니다
2. 문제 해결
1-1. 그럼 여기서 해결 방법은 spring 에서 단일한 Serive를 인식하게 해주어야 되는데 그럴때 사용하는 어노테이션
@Primary
---미세 조정 @Primary---
유형별 자동 연결은 여러 후보로 이어질 수 있으므로 선택 프로세스를 더 많이 제어해야하는 경우가 많습니다.
이를 수행하는 법은 Srping 의 @Primary 주석을 사용하는 것입니다
여러 빈이 단일 값 종속성에 자동으로 연결될 후보인 경우 특정 빈에 대해 Serivce를 등록시켜줄 수 있는 단일 Bean으로 설정할 수 있게 합니다.
즉, Srping 에서 두개로 인식하던 Bean을 선택 지정을 하게 해주면서 상단에 나와있는 에러를 처리할 수 있게 해줍니다.
이렇게 @primary를 붙여서 실행하면 문제 없이 에러를 해결하는 것을 알 수 있습니다.!
