哪种配置更适合数据持久性（GAE 目标）、GWT + Roo VS GWT +对象化应用程序引擎？
我正在为基于 GWT 的应用程序配置和选择架构组件。我必须选择一种简单的方法将我的数据模型保留在目标服务器上，即 Google-App-Engine。
参赛者：
Spring Roo：我已经尝试过并将其集成到我的项目中，效果非常好。似乎使用起来很简单，并且 java AspectJ ITD 似乎是一项非常酷的技术，可以帮助我生成和保存我的实体。目前它仅适用于 JPA，因此并没有真正发挥 DataStore 的真正潜力（仅限 RDBMS :(
< strong>Objectify：尚未尝试过，但直接解决 Google DataStore API 似乎很棒，我检查了示例用法，它看起来也非常好。
谢谢
！
I'm in the middle of configuring and choosing my architecture components for my GWT based we application. I have to choose a simple way to persist my data model on the target server which is Google-App-Engine.
Contestants:
Spring Roo: I've tried this and integrated it in my project and it's pretty nice. Seem to be simple to use and the java AspectJ ITD seem a very cool tech to assist me in generating and persisting my entities. For now it only works with JPA so, not really exploiting DataStore real potential (RDBMS only :(
Objectify: Not tried this one yet but it seems great to address directly the Google DataStore API. No fuzzle with JDO. I checked sample usage and it looks very nice too.
Does any experienced guy has an opinion?
Thank you!

我创建了一个未发布的 Roo 附加组件，它使用 Twig 来实现 GAE 持久性。 Twig 太棒了，几乎没有配置，只有当我过度时才会出现问题 -配置的东西。 GAE 上的 JPA 的问题在于它只是 JPA 1.0，并且 GAE 的 Datanucleus 插件充其量只是粗略的。
如果我只针对 GAE，我会使用 Twig 或 Objectify。如果您感兴趣，我可以将我的 Twig 插件发布为 Google Code 项目。
I created an unpublished Roo add-on which used Twig for GAE persistence. Twig is fantastic, there is almost no configuration and problems really only arose when I over-configured things. The problem with JPA on GAE is that it is only JPA 1.0 and it the Datanucleus plugin for GAE is sketchy at best.
If I were solely targeting GAE I would be using Twig or Objectify. If your interested I can publish my Twig add-on as Google Code project.
在 GAE 开发模式中，您只能以编程方式保留对象（我在过去 3 天中搜索了如何将数据从在线数据存储批量导入/同步到本地数据存储的解决方案，但似乎对于 java 应用程序没有简单的解决方案 - 至少我知道）但是如果你仍然想要 NoSQL，objectify gwt 对你来说是一个很好的解决方案。一票投给了 Objectify。
In GAE Development Mode you can only persist object programatically (I've searched in last 3 days for solution how to batch import/sync data from online datastore to local datastore but it's seem there isn't easy solution for java app - at least as I known) but objectify gwt is good solution for you if you still want NoSQL. One vote for Objectify.
