해결 : According to error log, a server is already started on port 8080. Either you start your server on different port or stop the previous server with port 8080. Go to windows task manager and end process javaw.exe
- 로그에 따르면 , server가 이미 8080 포트로 작동 중이다. 다른 포트를 사용해서 서버를 시작하거나 8080 포트를 사용하는 이전의 서버를 중단해야한다. 윈도우 사용 시 작업관리자로 가서 프로세스 java.exe를 중단해준다.

원인 : 8080포트가 안 꺼지고 남아있었기기 때문, 포트 충돌
