Loading class `com.mysql.jdbc.Driver'. This is deprecated. The new driver class is `com.mysql.cj.jdbc.Driver'. The driver is automatically registered via the SPI and manual loading of the driver class is generally unnecessary.

MySQL Connector 사용시 DriverClassName을 지정해 주어야 하는데 MySQL 버전 8부터는 com.mysql.cj.jdbc.Driver 를 권장하는 것으로 파악된다.

추후 버전이 더 올라가면 com.mysql.jdbc.Driver 클래스는 deprecated 되었기 때문에 삭제될 가능성이 높다.
