One day I woke up, ran my IntelliJ, started the app and had the same problem. For a solution please check:

1. Dependency 'mysql:mysql-connector-java' is exists.
2. Class 'com.mysql.cj.jdbc.Driver' is exists through global search(ctrl+shift+n) -> classes.
3. In IntelliJ: "File" -> "Invalidate Caches / Restart".
