Error] Could not create connection to database server.

spring.datasource.url=jdbc:mysql://localhost:3306/{schemaName}?serverTimezone=UTC&characterEncoding=UTF-8
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.datasource.username=root
spring.datasource.password=1234

서버타임존을 한국 시간으로 되야하는게 아닌가 하고 KST로 했었는데, 오류가 발생

 

UTC로 바꾸고 해결
