org.gjt.mm.msyql.Driver is an old class name kept around for backwards compatibility. org.gjt.mm.msyql.Driver是一个旧类名称，用于向后兼容。 Use com.mysql.jdbc.Driver instead. 请改用com.mysql.jdbc.Driver 。 See this MySQL reference for usage . 有关用法，请参见此MySQL参考。

First of all please check if you are having the mysql-connector-java.jar in your classpath, if not please get it from here and put it in the classpath 首先，请检查您的类路径中是否有mysql-connector-java.jar ，如果没有，请从此处获取并将其放入类路径中

The old classname org.gjt.mm.msyql.Driver is kept for backwards compatibility reasons, if you can, you should update it to com.mysql.jdbc.Driver 出于向后兼容的原因，保留了旧的类名org.gjt.mm.msyql.Driver ，如果可以，则应将其更新为com.mysql.jdbc.Driver
