Caused by: java.lang.RuntimeException: Failed to load driver class com.mysql.cj.jdbc.Driver in either of HikariConfig class loader or Thread context classloader code example
Example: reason: failed to load driver class com.mysql.cj.jdbc.driver in either of hikariconfig class loader or thread context classloader
