我正在尝试使用Spoon附带的JDBC驱动程序将勺子连接到Heroku PostgreSQL实例.Heroku需要SSL,因为它是独立的PostgreSQL实例,我已启用它.
我可以使用其他使用SSL的客户端软件连接到数据库,因此这似乎特定于Java/JDBC.我不太了解Java对此进行故障排除所以希望有人在此之前已经有过这样的事情.
我得到以下和相当详细的错误消息提到SSLHandshakeException,但我不确定这是否是其他原因或症状？也许我需要在Java中指定SSL证书？
Error connecting to database [XXXX.com] : org.pentaho.di.core.exception.KettleDatabaseException:

<hibernate-configuration>

<property name="hibernate.ejb.naming_strategy">org.hibernate.cfg.ImprovedNamingStrategy</property>

<property name="hibernate.use_outer_join">true</property>
<property name="current_session_context_class">thread</property>
</session-factory>
</hibernate-configuration>
另外,我动态地覆盖了一些属性......
Configuration config = new Configuration().configure("path_to_hibernate.cfg.xml");
config.setProperty("hibernate.connection.url", System.getenv("HEROKU_POSTGRESQL_MYCOLOR_URL"));
config.setProperty("hibernate.connection.username", "***");
config.setProperty("hibernate.connection.password", "***");
但是,当我运行它时,我收到此错误...
ERROR: No suitable driver found for postgres://*******:*********@ec2-23-21-85-197.compute-1.amazonaws.com:5432/d9i5vp******o7te
如何配置我的属性以便heroku找到postgres驱动程序？
(我是hibernate和heroku的新手,所以任何帮助都非常感谢:)
