是否有任何好的 ORM(最好是 JPA 实现)支持 SQLite(在 Android 上)? [英] Are there any good ORMs (preferably JPA implementations) that support SQLite (on Android)?

问题描述

我在不久前发现了一个帖子，它解决了一个类似的问题，但我认为它有点过时了.我意识到 JPA 的实现更倾向于重/密集方面，所以如果您知道任何轻量级(非 JPA)ORM，我肯定会感谢您的投入.我确实在另一篇文章中看到了关于 ActiveAndroid 的答案，我很想知道是否有人尝试过.>

更新:

最后，我决定采用更轻量级的解决方案并选择 DB4O.到目前为止，我对自己的选择非常满意.它非常容易使用，并且需要最少的配置.该网站包含丰富的信息，包括示例项目和深入的教程 几乎涵盖了开发人员可能需要了解的有关 DB4O 的所有内容.哦，我有没有提到它是免费的(不像其他一些替代品......coughActiveDroidcough)?

解决方案

关于 JPA 实现，至少有一个 SQLite 的第三方方言 用于 Hibernate.我不是 100% 确定，但 EclipseLink 似乎也是一个选项(尽管 SQLite 是未得到官方支持).

但对于 Android 开发，我肯定会检查 ActiveAndroid.

为了以防万一，这里有一些其他选择:jPersist、Ebean, Dreamsource ORM(查看公告在 TSS 上).

I found a post from a while ago that addresses a similar question but I think it's a bit outdated. I realize implementations of JPA tend to be more on the heavy/dense side, so if you know of any lightweight (non-JPA) ORMs I'll most certainly appreciate your input. I did see the answer about ActiveAndroid in the other post and am curious to know if anyone tried it out.

Update:

In the end, I decided to go with a more lightweight solution and chose DB4O. So far I've been very happy with my choice. It's extremely easy to use and requires a minimal amount of configuration. The website contains a wealth of information including sample projects and an in-depth tutorial that covers just about everything a developer might need to know about DB4O. Oh, and did I mention that it's free (unlike some other alternatives... coughActiveDroidcough)?

解决方案

Regarding JPA implementations, there is at least a third party Dialect for SQLite for Hibernate. I'm not 100% sure but EclipseLink seems to be an option too (although SQLite is not officially supported).

But for Android development, I would definitely check ActiveAndroid.

Just in case, here are some other alternatives: jPersist, Ebean, Dreamsource ORM (have a look at the announcement on TSS).
