제가 작성한 코드에서 의존성을 주입 받는 것들입니다.

실제로 실행 시 정상적으로 작동을 하는데 Test만 돌리면 Bean 등록에 실패했다는 문구가 나옵니다.

다른 부분은 문제가 없어보이고 ReviewGetService에서 Bean 등록 실패가 발생합니다.

아래는 예외 발생한 문구 입니다.

2023-06-14 02:04:52.885  WARN 97966 --- [    Test worker] o.s.w.c.s.GenericWebApplicationContext   : Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'reviewController' defined in file [/Users/siglee/Desktop/study/project/semi_project/devstore/BE/backend/build/classes/java/main/project/main/webstore/domain/review/controller/ReviewController.class]: Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'reviewGetService' defined in file [/Users/siglee/Desktop/study/project/semi_project/devstore/BE/backend/build/classes/java/main/project/main/webstore/domain/review/service/ReviewGetService.class]: Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.NoUniqueBeanDefinitionException: No qualifying bean of type 'project.main.webstore.domain.review.repository.ReviewRepository' available: expected single matching bean but found 2: reviewJpaRepository,project.main.webstore.domain.review.repository.ReviewRepository#0



Description:

Parameter 0 of constructor in project.main.webstore.domain.review.service.ReviewGetService required a single bean, but 2 were found:
	- reviewJpaRepository: defined in project.main.webstore.domain.review.repository.ReviewJpaRepository defined in @EnableJpaRepositories declared on JpaRepositoriesRegistrar.EnableJpaRepositoriesConfiguration
	- project.main.webstore.domain.review.repository.ReviewRepository#0: defined in unknown location


Action:

Consider marking one of the beans as @Primary, updating the consumer to accept multiple beans, or using @Qualifier to identify the bean that should be consumed


Caused by: org.springframework.beans.factory.NoUniqueBeanDefinitionException: 
No qualifying bean of type 'project.main.webstore.domain.review.repository.ReviewRepository' available: 
expected single matching bean but found 2: 
reviewJpaRepository,project.main.webstore.domain.review.repository.ReviewRepository#0

ReviewGetService 빈을 등록할 때 repository에 매핑될 빈이 1개여야하는데 2개라서 문제가 발생한 것이다. 라는 의미인 것 같습니다.

@SpringBootTest
class WebstoreApplicationTests {

	@Test
	void contextLoads() {
	}

}

에서 테스트 진행 시에는 또 잘 작동합니다.

다만 제가 테스트를 위해 만든 클래스들에서 @SpringBootTest 어노테이션을 이용해서 작업 시 모두 ReviewGetService 빈 등록 시 Repository때문에 문제가 발생한다 라는 문구가 발생합니다.

질문 1. 동일한 의존성을 가지는 ReviewService에서는 왜 이런 문제가 발생하지 않는 것인가?

질문 2. 이럴 경우 직접 Bean을 등록해줘야되는 것인가? 다른 해결 방법은 없는 것인가

입니다.
