단위 테스트를 작성하고 전체 프로젝트 빌드를 했더니 위와 같은 에러가 발생했다..

 

어떤 원인이 문제인지 확인해보려고하는데 찾아봐야 할 부분이 너무 많아서 계속 삽질 중이다,,

 

가장 일반적인 이유 중 하나는 프로퍼티 설정과 관련된 문제라고합니다. 

PropertyPlaceholderHelper.java:180를 보면 프로퍼티 관련 문제일 가능성이 있습니다. 이 경우, Spring의 프로퍼티 설정이나 @Value 어노테이션을 사용하여 프로퍼티 값을 주입하려고 할 때, 해당 프로퍼티가 정확하게 설정되지 않았거나 읽을 수 없는 경우에 발생할 것이라해서 좀 더 자세한 에러로그를 확인하기 위해 ./gradlew test -i로 스택을 찍어보겠습니다.

로그를 찍어보니까 securityConfig 관련 빈 생성 문제와 CustomOAuth2LoginSuccessHandler, jwtService 의존성 및 프로퍼티설정이 잘못됐다고 나왔다.

 

Caused by: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'securityConfig' defined in file
Caused by: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'customOAuth2LoginSuccessHandler' defined in URL
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'jwtService': Injection of autowired dependencies failed
Caused by: java.lang.IllegalArgumentException: Could not resolve placeholder 'jwt.token.key' in value "${jwt.token.key}"

 

아마도 @WebMvcTest를 사용해서 UserController에서 필요한 의존성들을 주입하면서 관련 에러들이 발생한 것 같다.

 

 

일단 우리 프로젝트는 멀티모듈을 사용하고있기때문에 상위 모듈의 application-api.yml 과 하위모듈의 application-core.yml이 둘다 잘 로드 되는지 확인해보자.

 

나는 두개의 yml 을 로드해야하기때문에 SpringApplication에 다음과 같이 설정해줬습니다.

@EnableJpaAuditing
@SpringBootApplication
public class SellyourunhappinessApiApplication {
    public static void main(String[] args) {
        System.setProperty("spring.config.name","application-api,application-core");
        SpringApplication.run(SellyourunhappinessApiApplication.class, args);

    }
}

 

 

 

디버거를 통해 로그를 찍어보니까 프로퍼티들은 둘 다 잘 로드되고있는 것 같다.

그렇다면 왜 도대체 application-core.yml에 설정되있는 jwt.secret 을 @Value에서 못받아갈까? 애플리케이션을 실행할땐 문제가없는데 빌드시에만 문제가 발생하고있다.

 

여러 해결책들을 찾아보니까  build.gradle에서 아래와 같은 부분을 지우는 방법은 근본적인 해결책을 찾는 방법들이 아니기 때문에 근본적인 원인을 고쳐야될 것 같다..

tasks.named('test') {
    useJUnitPlatform()
}

@Test
void contextLoads() {
}

 

 

테스트 코드에서 해당 빈들을 의존성 주입을 해주면서 해결이 되었다.

 

하지만 사용하지 않는 빈들을 의존성 주입해서 적용하는 방법은 좋지 않은 방법이니까 해당 빈들을 주입안해도되게 코드를

리팩토링해보자..
