[ERROR] Spring 5.3.XX / 404 Not Found Return

 

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 :

 

실행시 시작된 인터페이스는 200으로 뜸.

 

 

 

더불어 filter 단에서 찍히는 클라이언트 요청의 파라미터도 

 

 

컨트롤러 단에서는 찾아볼수도 없는 버그도 있었음.

 

 

다른 사람들은 ? 

 

 

 

https://stackoverflow.com/questions/70691545/http-status-404-not-found-java-spring-mvc

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.
