-------------------------------------------
1:下载驱动
https://dev.mysql.com/downloads/file/?id=468318
2、将对应的mysql驱动包（mysql-connector-java-5.1.15-bin）放到下kettle的目录：
\pdi-ce-5.2.0.0-209\data-integration\lib下或
\pdi-ce-5.2.0.0-209\data-integration\libswt\win64下
【我的电脑是64位的】
以下是，缺失MS SQLserver驱动，下载SQLserver的JDBC连接驱动jar导入
\pdi-ce-5.2.0.0-209\data-integration\lib下或
\pdi-ce-5.2.0.0-209\data-integration\libswt\win64下
然后重启spoon.bat即可。
