버그 내용

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'authController' defined in URL [jar:file:/app.jar!/BOOT-INF/classes!/gabia/cronMonitoring/controller/AuthController.class]: Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'authService' defined in URL [jar:file:/app.jar!/BOOT-INF/classes!/gabia/cronMonitoring/service/AuthService.class]: Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'tokenProvider' defined in URL [jar:file:/app.jar!/BOOT-INF/classes!/gabia/cronMonitoring/util/jwt/TokenProvider.class]: Unexpected exception during bean creation; nested exception is java.lang.IllegalArgumentException: Could not resolve placeholder 'jwt.secret' in value "${jwt.secret}"

• 버그 원인 : 이미지 빌드시 spring profile 미설정
• 발생 환경 : 배포 서버

버그 재현 코드

FROM openjdk:11
VOLUME /tmp
ARG JAR_FILE=build/libs/*-SNAPSHOT.jar
COPY ${JAR_FILE} app.jar
ENTRYPOINT ["java", "-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar"]

해결 방안

FROM openjdk:11
VOLUME /tmp
ARG JAR_FILE=build/libs/*-SNAPSHOT.jar
COPY ${JAR_FILE} app.jar
ENTRYPOINT ["java","-Dspring.profiles.active=prod", "-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar"]

• 빌드시 스프링 프로파일 명시

추후 고려사항

• config 관련 파일 수정시 도커파일도 함께 확인
