Java printed this

Caused by: java.lang.ClassNotFoundException: com.mysql.jdbc.Driver

What it meansThe JVM could not find the MySQL JDBC driver class on the classpath when your code or framework tried to load it at runtime.

The first thing to checkAdd the mysql-connector-j dependency to your build; with Connector/J 8 or later the class is com.mysql.cj.jdbc.Driver, so update the name too.
