타프로젝트를 받아왔는데 로그인시 뜨던 오류

추상메서드 오류라고 떠있었으나 무슨 문제인지 찾지 못함.

Java Build Path - Maven Dependencies의 jar파일 확인 결과 제대로 받아옴.

 

검색 후 톰캣버전문제, JDK 문제였다는 다른 개발자의 글을 읽고 두 가지를 다 시도해봄.

 

 

1. 톰캣 버전 변경

현재 톰캣 버전을 알기 위해서는 cmd 명령 프롬프트에서

cd C:\Program Files\Apache Software Foundation\Tomcat 7.0\bin 실행으로 알 수 있다.

현재 버전과 타프로젝트 버전을 확인하여 톰캣 새로 깔기(오류잡기 실패)

 

 

2. JDK 다운로드

JDK를 새로받아와서 클릭하면 자동적으로 깔림. 프로젝트 재 실행(성공)

 

https://www.oracle.com/technetwork/java/javase/downloads/index.html

java SE - download - java Archive - Java SE 8 (8u202 and earlier)

Java SE Development Kit 8u202란의 Windows x64 / jdk-8u202-windows-x64.exe 다운로드 

 

 

 

3. 그 밖의 시도

C드라이브 - 사용자 - .m2 - repository안의 폴더 삭제 후

서버 재가동 (오류잡기 실패)
