spring.datasource.username=spring@$AZ_DATABASE_NAME
spring.datasource.password=$AZ_MYSQL_PASSWORD

spring.datasource.initialization-mode=always

spring.datasource.initialization-mode=always 구성 속성은 서버가 시작될 때마다 Spring Boot에서 나중에 만들 schema.sql 파일을 사용하여 데이터베이스 스키마를 자동으로 생성함을 의미합니다. 

이는 테스트에 유용하지만, 다시 시작할 때마다 데이터가 삭제되므로 프로덕션에서 사용하면 안 됩니다!

?serverTimezone=UTC를 spring.datasource.url 구성 속성에 추가하여 데이터베이스에 연결할 때 UTC(협정 세계시) 날짜 형식을 사용하도록 JDBC 드라이버에 지시합니다. 

그렇지 않으면 Java 서버에서 데이터베이스와 동일한 날짜 형식을 사용하지 않으므로 오류가 발생합니다.
