我正在使用 Spring Social Facebook 插件；我有一个非常简单的场景：我想在我的网页上显示我的用户帐户提要；到目前为止，我已经构建了一个非常简单的 JUnit 测试以列出我的 FB 墙贴，但是我在使用 Spring Social 集成时遇到了一些问题我使用的是 spring 4.0.5 和 spring social 1.1.0
从我在文档中看到的，我不需要使用 spring 社交连接框架（也许我将来会使用 ConnectionRepository 以便不总是对每个请求进行 FB 和/或 twitter 连接，但现在我不需要处理多个用户）
所以，在我在FB上创建了一个测试APP并获得了appClientID和appClientSecret之后，我编写了这个简单的XML配置：
