问题描述
上次我听到很多关于hibernate的抱怨。事实上，我对hibernate也有一些痛苦的经历。所以我读到了和。
In the last time I heard a lot of complaining about hibernate. And indeed I have some painful experiences with hibernate too. So I read about Ebean and Siena.
两者都有有趣的方法。不幸的是，数据库访问层很容易编写，但是如果你的项目增长并且你必须处理好的数据库表，你就会知道它们是否好。所以评估这样一个工具真的很难。 Hibernate是众所周知的，你可以肯定你可以解决它的问题。有时你需要学习很多东西，但你可以解决它。
Both have interesting approaches. Unfortunately, database access layers are very easy to write, but if your project grows and you have to handle great database-tables, you know if they are good or not. So it's really difficult to evaluate such a tool. Hibernate is well known and you could be sure that you can solve your problem with it. Sometime you need to learn a lot, but you can solve it.
Ebean怎么样？有没有真实的应用程序？支持哪些数据库？它是否可靠？
How is it with Ebean? Are there any real world applications? Which databases are supported? Is it reliable?
在搜索了一点之后我发现有更多的ORM框架，那么至少有一个可靠的框架吗？
After searching a little bit more I see that there are a lot more ORM-frameworks, so is there at least one reliable one?

Ebean大约4岁以上现在。我会说它现在相当成熟。支持的数据库包括Oracle，MySql，Postgres，H2和SQL Server（以及最近的SQLite）。 Ebean正在做其他ORM不像Autofetch（自动查询调优）的东西，所以我不是那么适合'成熟度评级'。 IMO Ebean社区相对较小，但你可能需要点击Ebean谷歌小组来吸引他们。
Ebean is about 4+ years old now. I would say it is fairly mature now. The supported DB's include Oracle, MySql, Postgres, H2 and SQL Server (and recently SQLite). Ebean is doing stuff that other ORM's are not such as Autofetch (automatic query tuning) so I'm not how that fit's into a 'maturity rating'. IMO the Ebean community is relatively small though so you probably need to hit the Ebean google group to engage them.
任何真实世界的应用程序？是的，但你最好向Ebean社区询问这个问题。当然，对批处理有很好的支持（批量大小，为事务等级转换级联等）和我在JPA等中没有看到的大型查询支持（你可能会得到与Hibernate的Sessionless支持类似的东西）。
Any real world applications? Yes, but you are best to ask the Ebean community about that really. Certainly there is good support for batch processing (batch size, turn of cascading persist for a transaction etc) and large query support that I don't see in JPA etc (you might get something similar with Hibernate's Sessionless support).
希望这可能会回答你问题的一些小部分。
Hopefully this might answer some small parts of your question anyway.
干杯，Rob。
