PutMapping 405 error 관련 질문드립니다

• 왜 안되지 싶어서 이것저것 해보다 잘못된 스크린샷을 올린것 같습니다.

• 위에서 405 에러라고 말씀드렸는데 400 에러가 발생합니다

에러 메시지

• 아래 에러 메시지에서 "trace" 부분을 보면 UpdateMemberRequest 를 생성할 수 없다는 메시지가 나오는데. 이것이 무엇을 의미하는지 잘 모르겠습니다 ㅠㅠ

• 생성자 관련 오류라면 이미 컴파일 오류 등으로 인텔리제이에서 보였을 텐데, 관련 부분은 없었습니다

해결이 안될 경우 댓글남겨주세요

감사합니다! 해결되었습니다!

final 키워드가 없을때 스프링 부트에서는 모든 클래스에서 디폴트 생성자를 다 따로 만들어 주어야 하는것 일까요?

스프링부트를 사용한다고 해서 기본생성자가 강제되지는 않습니다.

JPA의 Entity 사용 시 리플렉션을 이용하기 때문에 기본생성자가 필요합니다.

감사합니다!
