将Heroku Postgres DB连接到Kettle

Question

我想将水壶连接到heroku上的postgres db，以上传一些数据。 在Kettle中，我建立了一个新的数据库连接，在连接类型中，我选择了PostgreSQL，然后将在heroku上找到的所有设置都放入了数据库，但是与数据库的测试连接失败。 这是我收到的日志

Heroku以能够强制与数据库建立安全连接而自豪，因此您应该在连接中添加参数ssl = true。 另外，您可能需要编辑帖子以消除其余的隐私问题。

编辑1：要使用驱动程序参数而不是连接URL的一部分，请打开数据库连接对象，然后在“选项”页面上添加参数。

Edit2：通过将Java VM证书添加到truststore中，确保已准备好接受Java证书。
