(Kotlin)Multi-Module-Gradle 프로젝트 첫 실행 시 Parameter 0 of constructor in com.zerobase.api.test.TestService required a bean of type 오류

현재까지 진행한 것

최상위 폴더에서 build.gradle.kts 세팅

domain 모듈에서 build.gradle.kts(:domain), appllication-domain.yml에 DB접속정보 설정, Entity, Repository 생성

api 모듈에서 build.gradle.kts(:api), application.yml에 domain과 같은 설정 넣어주는 코드 작성. 

  그리고 db접근이 잘 되나 보려고test 패키지에 TestController, TesetDto, TesetService 생성.

 

ApiApplication.kt 생성 후 실행하니 다음과 같은 오류 발생

Description: Parameter 0 of constructor in com.zerobase.api.test.TestService required a bean of type 'com.zerobase.domain.repository.UserInfoRepository' that could not be found. The injection point has the following annotations: - @org.springframework.beans.factory.annotation.Autowired(required=true) Action: Consider defining a bean of type 'com.zerobase.domain.repository.UserInfoRepository' in your configuration. Process finished with exit code 1

딱 봐도 빈 등록이 안 된다는 오류 같아서 원래 강사님 설명에는 없었던

두 개의 Repository에 @Repository 어노테이션 붙여주고 메인 클래스있는 곳에서

@SpringBootApplication
@EntityScan(basePackages = ["com.zerobase.domain"])
@ComponentScan(basePackages = ["com.zerobase"])
@EnableJpaRepositories(basePackages = ["com.zerobase.repository"])
@EnableCaching
class ApiApplication

fun main(args: Array<String>) {
    runApplication<ApiApplication>(*args)
}

이렇게까지 다 해주었는데 자꾸 같은 오류가 발생했다...

언어도 낯설고 어려운데 하나 할 때마다 자꾸 오류가 발생하니...

 

ㅋ ㅋ 근데 방금 포스팅 하느라 코드 가져오면서 발견한 건데

@EnableJpaRepositories에 basePackages 주소로 "com.zerobase.domain.domain.repository"를 해줘야 한다 !

내가 패키지를 그렇게 만들었기 때문 .. ㅋ ㅋㅋ

 

이렇게 바꾸니까 정상 동작 !

 

------------------

여기서 하나씩 지워보면서 어떤 것 때문에 안 된 건지 체크해보려고 한다.

 

1. 일단 Repository 파일에 @Repository가 안 붙어도 된다 !

자동으로 이 패키지를 스캔하면서 빈으로 등록이 되는 듯 ???

 

근데 인제 Repository파일에 @Repository가 붙어도 현재 main이 있는 api 모듈에서는 거기를 찾을 수가 없나보다

@EnableJpaRepositories(basePackages = ["com.zerobase.domain.repository"])

이 부분은 필수라는 것을 알았고 

 

2. TestController와 TestService에서 의존성이 필요한 부분들

private val testService: TestService

private val userInfoRepository: UserInfoRepository

에 @Autowired를 넣어주었는데 이 부분을 빼도 정상동작 한다.

 

3. ComponentScan을 빼면 ? 

정상동작한다.

그치만 나중을 위해 일단 넣어놔주도록 한다.

 

4. @EntityScan을 빼면 ? 

오류가 난다.

무슨 오류인가 보면 testController Bean을 등록하는데 오류가 났다고 하고

testService도 , userInfoRepository도 bean등록에 오류가 났다고 한다. 

마지막에는 UserInfo라는 Entity를 찾지 못 한 것 같다.

 

조금만 생각해봐도 이해가 되는게 EntityScan을 빼서

UserInfo라는 Entity를 찾지 못 하므로

UserInfo라는 Entity에 의존성을 가지고 있는 userInfoRepository도 생성이 되지 못 했을 것이고

userInfoRepository를 의존하는 userService도 생성 못 하고

userService를 의존하는 controller도 빈으로 생성이 되지 못 한 것이다 !

후.. Multi Module로 프로젝트를 진행하니까 설정 파일도 제각각 많아져서 뭔가 더 어려워진 느낌이다..

정말 큰 도움 받은 곳 .. 어디에서도 EnableJpsRepositories 어노테이션을 붙이라고는 안 했는데 여기서 알려주셨다 ㅠ
