 发现，其实在报Mysql驱动没有找到！

所以，我们就去Mysql官网 https://dev.mysql.com/downloads/connector/j/  下载 mysql-connector-java-5.1.44.zip，解压得到 mysql-connector-java-5.1.44-bin.jar 

并将mysql-connector-java-5.1.44-bin.jar 复制到kettle 安装目录 （即Spoon.bat存在的路径）D:\software\6.1\pdi-ce-6.1.0.1-196\data-integration下面。

再重启Kettle，就OK了！
