springboot프로젝트의
application.properties (경로 : src/main/resources/application.properties)
에서 spring.datasource 제대로 안해줘서 생긴 에러
spring.datasource.url=jdbc:mysql:tcp://localhost:3306/cos-blog
(url설정인데 여기서 실패하는 것 같음 tcp도 뺴줘야할듯)
spring.datasource.username=cos (아이디)
spring.datasource.password=cos1234 (비밀번호)
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
(드라이버 클래스 이름com.mysql.cj.jdbc.Driver / com.mysql.jdbc.Driver
둘 중 하나지만 후자는 레거시인듯? Deprecated라고함)

java.sql.SQLSyntaxErrorException: Unknown database 'cos-blog'......
(cos-blog라는 database를 못찾는다고 한다 blog
spring.datasource.url=jdbc:mysql:tcp://localhost:3306/cos-blog
->
spring.datasource.url=jdbc:mysql://localhost:3306/blog
(url 제대로 변경해줘서 성공)
cos-blog는 connection name이고 blog가 dabase name인듯..
spring.datasource.url=jdbc:mariadb://(RDS 엔드포인트):(포트명)/(데이터베이스이름)
spring.datasource.username=(db 계정)
spring.datasource.password=(db 계정 비밀번호)
spring.datasource.driver-class-name=org.mariadb.jdbc.Driver
여차저차 또 해봤지만 그 이후에도 무수한 exception의 요청이..ㅠ
알고보니 pom.xml(Maven빌드툴이라 이거씀)의
jpa dependency 주석처리 안해줘서 이렇게 됐음..
