여러 방법을 다 써봤지만 실패한 상황에서 SecurityConfig에서

baseurl이라 되어있는 부분을

oauthConfig.authorizationEndpoint {
    it.baseUri("http://localhost:8080/oauth2/login") // 로컬호스트로 설정
}.redirectionEndpoint {
    it.baseUri("http://localhost:8080/oauth2/callback/kakao") // 로컬호스트로 설정
}.userInfoEndpoint {

이렇게 바꿔보았는데,

jwt 오류 대신

Whitelabel Error Page

This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Internal Server Error, status=500).

이렇게 나오기 시작했다. 우선 뭔가 변화는 있었기 때문에 이쪽을 해결해 보려고 한다.

그리고 디버그는

이렇게 나오는데, org.example.domain.user.UserController.handleKakaoCallback 메소드에서 oAuth2User 파라미터가 null로 전달되는 NullPointerException이 나온 모양이다. 내가 그걸 바꿔서인지, 아니면 여러 시도중에 발생한 문제인지 확실치 않아서 조사중이다.
