2/7

💡공부하고있는 maven spring project의 생성/개발과정을 기록하는 공간입니다.
혹시 잘못된 부분이있거나 해주실 말씀이 있다면 언제든 댓글 남겨주세요 😊

이부분...하면서 알수없는 오류가 너무 많이나서 프로젝트 다시 밀고 깐것만 두번...ㅎㅎ 3일동안 땅파다가 드디어 해결했어욥 ㅠㅠ

🌟 project tree structure

🌟 pom.xml 설정 (framework 등)

💥 (properties에 정의 안해주고 ${spring.version} 사용하면 오류..!

https://mvnrepository.com/
여기에서 원하는 maven 버전을 확인하고 복사해서 pom.xml에 붙여넣기하면됨!

🌟 web.xml 오류사항

Element type "application" must be followed by either attribute specifications, ">" or "/>"

1번째줄에 빨간줄이 그어지면서 오류가 났었음

📌 해결 : space바로 했던 web-app쪽의 들여쓰기를 tab으로 변경해서 들여쓰기해주니까 오류 해결...^^;; 이유는 모르겠다.

🌟 context-datasource.xml 생성

📌 정말...애먹었던 context-datasource 오류....

cvc-elt.1.a: 'beans' 요소의 선언을 찾을 수 없습니다.

이부분을 아래코드처럼 바꾸니까...! 해결됨! (이유는 모르겠음....)
