SpringBoot와 MySQL 도커 배포 과정에서 계속 오류가 발생합니다.

선배님들 안녕하십니까? 제목 그대로 스프링부트와 MySQL 배포 과정에서 HikariPool-1 - Exception during pool initialization. server-1 | server-1 | java.sql.SQLNonTransientConnectionException: Could not create connection to database server. Attempted reconnect 3 times. Giving up. 위와 같은 오류가 발생합니다. MySQL은 정상적으로 배포가 되어서 접근이 가능한 것을 확인했습니다. 하지만, SpringBoot의 경우, 계속 DB와 연결이 실패합니다. 아래는 SpringBoot의 application.properties 파일과 docker-compose.yml 파일입니다. 한 수 가르쳐주셨으면 합니다. 감사합니다. spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver spring.datasource.url=${SPRING_DATASOURCE_URL} spring.datasource.username=${SPRING_DATASOURCE_USERNAME} spring.datasource.password=${SPRING_DATASOURCE_PASSWORD} spring.jpa.show-sql=true spring.jpa.hibernate.ddl-auto=update spring.jpa.properties.hibernate.format_sql=true

aws spring boot 배포 오류

안녕하세요 백엔드 공부 중인 학생입니다. aws ec2로 Spring boot 프로젝트를 배포 시도 중에 있습니다. (maven, java 8, jar) java -jar jar파일명.jar 명령어로 배포 시도 중에 에러메세지가 도저히 해결이 안되어서 도움 요청드립니다.. 도와주신다면 감사하겠습니다.. 아 참고로 rds로 데이터베이스 생성하지 않고 mysql(workbench)로 데이터베이스 생성했습니다 <오류메세지> Error starting ApplicationContext.

신입 고졸 개발자에게 필요한 것이 궁금합니다

저는 이제 25인 된 고졸 개발자입니다 제가 부족한 부분과 더 배워야하는 것 그리고 제 기술로 취업이 가능한지 궁금합니다 제가 사용가능한 기술은 언어 : JAVA, Python, C, html, Javascript 프레임워크 : Spring, Django, Swing DB : Oracle, Mysql, hibernate, JPA 기타 : Spring Security, OOP, gradle.build(kts), Ajax, Aws, Liunx(centOs7, ubuntu) 위 내용정도 프로젝트에 사용해 보았습니다

튜토리얼 지옥에 빠진 취준생입니다ㅠ

취업용 프로젝트 하나 만들고 싶습니다 웹개발 백엔드 지망입니다 프론트을 못만들어서 빌빌거리고 있습니다 리액트 튜토리얼 영상보고 따라치고 이제 어떻게 만들어야 하지?하고 있습니다 리액트는 어렵다느끼고 타임리프를 써보자 하다가 얘도 시간 좀 걸리겠네 Jsp하자 하다가 결국엔 다시 리액트로 가고 어떻게 만들어야하는지 몰라서 우데미 강의 듣고 있습니다 쓰면 쓸수록 한심하네요 그냥 푸념글이 된 것 같습니다 죄송합니다… 백엔드는 스프링 부트 crud 프로젝트로 Hibernate 가능합니다. 스프링 레거시 프로젝트도 가능하구요 Aws와 docker로 배포도 해보았습니다 웹서버는 nginx를 사용했습니다. 위의 배포 관련 기술들은 사용만 해보았고 문제가 생기면 아마 처리 못할 것 같습니다.
