主機名       : 127.0.0.1
埠           : 3306
資料庫名:vincent

kettle版本8.2，JDK版本1.8.0_261，MYSQL版本8.0.19

問題很明顯，資料庫驅動問題，在遇到這個問題查詢解決方案時，在網上搜索到千篇一律的答案，即在data-integration\lib目錄下放入mysql-connector-java.jar包即可。

一般都能解決大部分人的問題，可以嘗試了N多姿勢就是不行

這裡直接自定義連線即可

把對應版本的java包放到data-integration\lib目錄下

不用加這麼多次引數也行的

簡單的

自定義連線URL（中文換成你的資訊）
jdbc:mysql://IP地址:3306/要連線的資料庫?&serverTimezone=Asia/Shanghai

自定義驅動類名稱：
com.mysql.cj.jdbc.Driver
