我有一个 Spring MVC 4.0.1 Web 应用程序，需要将文件上传到 Rackspace Cloud Files。我正在使用 Apache jClouds 来做到这一点。尝试使用以下代码创建 BlobStore 时：
BlobStoreContext context = ContextBuilder.newBuilder("cloudfiles-us").credentials("username","password").buildView(BlobStoreContext.class);
我得到以下异常：
com.google.inject.CreationException: Guice creation errors:

我无法弄清楚这一点，因为此时它几乎是示例代码的第一行......
