Kettle运行报错 Establishing SSL connection without server‘s identity verification is not recommende...

完整报错信息如：

WARN: Establishing SSL connection without server's identity verification is not recommended. According to MySQL 5.5.45+, 5.6.26+ and 5.7.6+ requirements SSL connection must be established by default if explicit option isn't set. For compliance with existing applications not using SSL the verifyServerCertificate property is set to 'false'. You need either to explicitly disable SSL by setting useSSL=false, or set useSSL=true and provide truststore for server certificate verification.

解决方法，是在连接转换的配置文件中，增加如下：

<attribute>
        <code>EXTRA_OPTION_MYSQL.useSSL</code>
        <attribute>false</attribute>
 </attribute>

示例如：

我这边是嵌入在 springboot中，其他kettle设置类似这个配置，注意一定要在  connection下。
