java - jclouds 与 OpenStack => java.util.NoSuchElementException : apiType compute not found in catalog []

Question

Java jclouds API 无法连接到 OpenStack 提供程序。

抛出异常并显示以下消息:java.util.NoSuchElementException:在目录 [] 中找不到 apiType 计算。

其他 API(python-novaclient、ruby-fog)工作得很好，因此问题看起来是特定于语言 (API) 的。

      try {

         jcloudOpenStack.close();
      }
      catch (Exception e) {
         e.printStackTrace();
      }
      finally {
         jcloudOpenStack.close();
      }
   }

   private void init() {
      Iterable modules = ImmutableSet. of(new SLF4JLoggingModule());

      String provider = "openstack-nova";
      String identity = "...";   // login name
      String password = "...";   // password

      ComputeServiceContext context = ContextBuilder.newBuilder(provider)
            .endpoint("https://UltiCloud.com:5000/v2.0/")
            .credentials(identity, password)
            .modules(modules)
            .buildView(ComputeServiceContext.class);
      compute = context.getComputeService();
      nova = context.unwrap();
   }

   private void listServers() {
      Set<? extends ComputeMetadata> nodes = compute.listNodes();
      System.out.println(nodes.size());
   }

   public void close() {
      closeQuietly(compute.getContext());
   }
}

非常感谢任何帮助或提示

这几天我也遇到了同样的问题，终于解决了。 您应该使用“用户名:租户名”作为“凭据”函数的参数“身份”。 如果您使用“username”而不是“tenantname:username”，jclouds 将仅查询 token ，而不是在 token 查询后查询端点列表，并抛出异常。

看起来像这样:

  ComputeServiceContext context = ContextBuilder.newBuilder(provider)
        .endpoint("https://UltiCloud.com:5000/v2.0/")
        .credentials("admin:admin", "123456")
        .modules(modules)
        .buildView(ComputeServiceContext.class);

不是这样的:

  ComputeServiceContext context = ContextBuilder.newBuilder(provider)
        .endpoint("https://UltiCloud.com:5000/v2.0/")
        .credentials("admin", "123456")
        .modules(modules)
        .buildView(ComputeServiceContext.class);

希望对大家有帮助
