kettle 在linux 环境下执行时报以下错误：
Sun Jul 12 12:06:56 CST 2020 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.
这句话的谷歌翻译为
看了谷歌的翻译后，大致明白是什么意思，在jdbc连接设置useSSL = false
方法：设置连接方式
url: jdbc:mysql://localhost:3306/test1?useUnicode=true&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=UTC&useSSL=false
在kettle 上设置方式
1.点开数据库连接，进行编辑，如下图
