java - 在Spring MVC应用程序中使用jclouds创建BlobContext时出错

我有一个spring mvc 4.0.1web应用程序,需要将文件上传到rackspace云文件。为此,我使用apache jclouds。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:

我想不通,因为这几乎是示例代码的第一行……

最佳答案

你是在用java 7u51运行jclouds 1.6.x还是1.7.0?如果是,您可能遇到了https://issues.apache.org/jira/browse/JCLOUDS-427。您可以通过降级到java 7u45或升级到jclouds 1.7.1来解决这个问题。
