반응형
신규 프로젝트에서
스프링 4.2.3 버전을 쓰다가 5.3.13 버전으로 버전업을 했다.
일단 첫째로 라이브러리 호환 안되는 경우 체크
+ 저번에 보아두었던 RestTemplate 말고 WebClient 메서드를 알아 보려고 했는데 테스트용으로 가볍게
API를 호출했던 결과 404만 뱉어냈다.
swagger-ui.html 관련 페이지를 호출하는 경우도 모두 마찬가지였다.
당시의 로컬 호스트 로그 기록 :
더불어 filter 단에서 찍히는 클라이언트 요청의 파라미터도
컨트롤러 단에서는 찾아볼수도 없는 버그도 있었음.
다른 사람들은 ?

HTTP Status 404 - not found - Java Spring MVC

해결한 질문이 아님.
404 Error 와 콘솔 및 서버에 정확한 에러 로그가 있지 않다면 해결책을 찾기가 쉽지 않다.
🥐해결한 경우는
이전 스프링 버전의 충돌, 라이브러리 버전 충돌을 의심했기 때문에 인텔리제이의 LIB / TARGET 경로 등을 전부 청소
하고
특히 인텔리 제이의 타겟 패스 및 환경 설정을 다 날리고 처음부터 다시 ( 라이브러리 포함 ) 다운받는 작업을 헀다.
같은 실수를 반복하지 않고 싶다. 정말 많은 시간을 허비했다.
가벼운 Web.xml 및 기타 설정을 여기 기록한다.

나같은 경우는 설정상의 문제였지만,
그 외에 다양한 에러 원인이있다. 404는 한가득 나올 가능성이 많으니까.
