스프링 클라우드 설정 중 위와 같은 에러를 만났습니다.
😛 원인
스프링 버전 별로 호환되는 스프링 클라우드 버전이 있었습니다.
현재 저는 Boot는 2.6.7 버전을 사용 중인데
Cloud 는 Hoxton 버전을 사용하려고 했기 때문에 호환이 안되서 발생한 오류였습니다.
버전 확인은 공식사이트 에서 확인할 수 있습니다.
🤔 어떤 버전을 선택하면 되지?
위와 같이 버전 옆에 -M3 나 -RC1 이 붙은 건 피해서 사용하시길 바랍니다.
RC1 (Release Candidate 1)
- 안정화가 될 후보 버전
M1, M2, M3 (Milestone)
- 개발 중인 버전
이렇게 옆에 아무것도 안 붙여져 있는 게 안정화버전 이니 안정화버전을 찾아 사용하시면 될 것 같습니다!
😎 결론
다들 각자 Boot 버전에 맞는 Cloud 버전을 설정하시길 바랍니다!
피드백은 언제나 환영입니다!
