헤로쿠가 막상 쓰려면 프리 티어에서 이런저런 제약조건이 있어서 귀찮긴 하죠 ㅋㅋㅋ1. 전 스프링 부트 말고는 안 써봐서 다른 경우는 모르겠지만 그래들이나 메이븐 기반 스프링 프로젝트라는 가정 하에 해당 repository를 push 하거나 해서 변경사항을 반영시키면 헤로쿠 쪽에서 알아서 빌드해서 jar 파일을 가지고 배포해주는 걸로 알고 있습니다.2. Favicon 저거는 브라우저가 웹 사이트에 접근하면 기본적으로 패비콘이라는 아이콘을 불러오는데 서버 자체가 H10이라는 에러 때문에 안떠있으니까 계속 에러가 발생하는 것 같습니다.3. 저도 스프링부트 &#43; MariaDB &#43; Hibernate 기반으로 처음 배포했을 때 비슷한 문제가 있었는데 hibernate dialect를 설정해줘야 했던 걸로 기억합니다. 혹시나 해서 올려주신 로그 확인해보니까 중간에 2022-08-04T15:26:45.143072&#43;00:00 app[web.1]: Caused by: org.hibernate.HibernateException: Access to DialectResolutionInfo cannot be null when 'hibernate.dialect' not set 라는 부분이 있네요. 애플리케이션 프로퍼티에 사용하시는 DB에 맞는 dialect를 설정해주시면 될 것 같습니다.... 추가적으로 나중에 헤로쿠에서 MariaDB 데이터베이스 애드온을 받아 쓰신다면 참고하실 점이 프리 티어는 커넥션이 10개로 제한되어 있더라구요. 근데 스프링 부트가 기본적으로 10개를 잡아먹어서 나중에 직접 데이터베이스에 접근하려고 할 때 여유 커넥션이 없어서 못 가져가는 경우가 있으니 커넥션 갯수를 9개로 제한해두시는 것도 좋습니다.
