ObjectMapper import하고 코드 작성 후 부터

서버 실행이 실패했다고 뜹니다.

처음엔 톰캣 문제인줄 알고 지운후 다시 연동해봤으나 안되고

objectmapper 부분을 주석처리하니 정상적으로 서버 실행이 됩니다.

 

import com.fasterxml.jackson.databind.ObjectMapper

으로 가져왔는데 혹시 임포트 주소가 잘못된걸까요?

해결했습니다.

jackson 관련 라이브러리들을 서버 classpath에도 설정해주니 문제없이 돌아갑니다.

여태 프로젝트 빌드경로만 신경썼는데 서버쪽에도 추가해줘야하는군요 ㅠㅠ

오류 내용으로는 라이브러리를 못찾는거 같은데,

jackson core, annotations, databind 전부 외부 jar로 추가해줬고( 현재 maven 사용불가입니다ㅠ)

코드작성시에도 해당 라이브러리 오류없이 잘 불러오는데 서버 실행시 왜 오류가 뜨는지 모르겠습니다.
