이렇게 다 했는데 localhost:8080 누르면 아무 화면도 나오지않습니다. 어떤 오류때문에 그런 것인지 알 수가 없습니다.
감사합니다.

안녕하세요, 인프런 AI 인턴입니다.
whdk333님의 코드를 살펴보았을 때, 문제의 원인이 될 수 있는 몇 가지 포인트를 짚어 보겠습니다.
컨트롤러 설정 확인:
HomeController에서@RequestMapping("/")을 통해 매핑된 URL이 올바르게 작동하는지 확인하셔야 합니다./경로로 요청이 올바르게 도달하는지 로그를 통해 확인해 보세요.Thymeleaf 설정 확인: 반환된 문자열 “home”이 Thymeleaf를 통해 올바른 뷰로 매핑되고 있는지 확인하세요.
resources/templates디렉토리 내에home.html파일이 존재하는지 확인해 보세요. Spring Boot는 Thymeleaf 설정이 올바르게 되어 있다면, 이 경로에 있는home.html을 찾아 렌더링을 시도합니다.정적 자원 경로 확인: CSS, JS와 같은 정적 자원의 경로가 올바른지 확인하세요. Spring Boot에서는 정적 자원을
resources/static디렉토리 아래에 두면 자동으로 제공됩니다. 만약 정적 자원의 경로가 잘못되어 있거나 파일이 누락되었다면, 페이지가 제대로 렌더링되지 않을 수 있습니다.스프링 부트 로그 확인: 애플리케이션 실행 시 콘솔 로그에 오류 메시지가 없는지 확인해 보세요. 스프링 부트는 애플리케이션이 시작할 때 중요한 정보를 로그를 통해 출력하기 때문에, 여기서 문제의 원인을 찾을 단서를 얻을 수 있습니다.
이 평가를 토대로 애플리케이션이 올바르게 작동하지 않는 구체적인 이유를 찾기 위해 하나씩 확인해 보시기 바랍니다. 문제가 해결되지 않을 경우, 보다 상세한 오류 메시지나 로그 내용을 함께 제공해 주시면, 좀 더 구체적인 해결 방안을 모색할 수 있을 것입니다.
감사합니다.
댓글 감사드립니다.
위의 방법들로 다 해봤습니다. 컨트롤러 설정도 확인했고, 타임리프도 잘 설정됐고, css외 js도 올바르게 들어갔습니다. 스프링부트 로그 오류메시지도 딱히 없습니다. 어떤 것이 문제일까요??
