我收到此错误，但我的 mysql-connector-java-5.1.23-bin.jar 在 Pentaho\data-integration\libext\JDBC 内。似乎未加载连接器，因为它使用的是默认连接器。我尝试了不同版本的 jdbc，我检查了 MD5，并且我在同一个文件夹中没有相同驱动程序的其他版本。我非常渴望完成这项工作，任何建议表示赞赏。

这是我尝试写入数据库时​​的输出：

你确定那不是服务器端的问题吗？您可以使用相同的凭据/驱动程序连接到该数据库并使用 SquirrelSQL 或其他一些 SQL 工具手动截断该表吗？还要确保从运行 PDI 的同一主机连接，也许有一些特定于主机的权限/限制。
