스프링부트 자바 jar로 배포하기 본문
❇ 스프링부트 자바 jar로 배포하기
이클립스 전산을 열어 스프링부트를 실행시킨 후(백앤드 실행) 프론트앤드 (리액트)를 실행하여
localhost로 접속하였는데 스프링부트자바를 jar로 배포시 이클립스 전산을 키지 않고
cmd창에서 실행 시킬 수 있다.
✓ 우선 위와 같은 작업을 진행하기 위해 첫번째로 해당폴더 경로 build.gradle이 있는 위치에서 cmd 창을 열어준다
✓ 백엔드 자바 배포
cmd 창에 gradle build 입력후 엔터를 친다!

[에러 내용과 해결 방안]
위 에러는 자바가 11버전이여서 나타난 오류로 java17버전으로 재설치후 환경설정을 진행해줘야 한다.

▶ 1~3번 경로로 들어가 환경변수 편집에서 숫자 11을 17로 변경후 확인/확인/확인을 눌러주었다!
✓ 이제 자바버전을 17버전으로 맞춰으니 아래의 경로로 자바버전을 확인해준다
✓ 이제 다시 백엔드 자바 배포를 진행하로 간다.

위와 같이 BUILD SUCCESSFUL이 뜨면 jar 파일로 만들어졌다!
✓ 이제 폴더 경로에 build폴더 생성되었는지 확인한다
build폴더에서 libs폴더로 들어가면 jar파일을 확인할수 있다. 해당폴더 경로에서 cmd창을 입력한다.

->위 에러를 해결해줘
[에러발생원인과 해결]
해당 에러는 이미 다른프로그램이 9090번 포트를 사용하고 있어서 발생한 문제로 해당 포트를 꺼주면 된다!
난 이전 프로젝트 9090포트가 실행중이여서 발생한 문제거 해당포트를 끄고 재 실행시 정상적으로 작동하였다!
또는 애플리케이션이 다른 포트를 사용하도록 설정하는 방법이 있다.
