我正在尝试在使用 Json 的 Google App Engine (Java) 上创建一个 RESTful Web 服务客户端。我试过 Sitebricks 和 Jersey，但它们似乎都不起作用。是否有任何框架可用于在 GAE 上创建 RESTful Web 服务客户端？

Sitebricks 的例外情况：

google-api-java-client怎么样？

在某种程度上，您所需要的只是发出 HTTP 请求并将响应解析为 JSON 的能力。除了使 Jersey/Sitebricks 对您更具吸引力之外，您还在寻找哪些功能？

试试jello-framework。它允许您通过 RESTful (OData) 服务公开您的数据模型，并提供开箱即用的 UI 视图，以便您可以测试您的应用程序并立即开始与数据交互。

披露 - 我是 Jello 框架的创建者。尽管如此，我还是决定将它添加为 GAE 上 RESTful 客户端的有效答案，因为它可以为所提出的问题提供一个很好的解决方案。
