我有一个小程序在尝试获取Azure德国云的访问令牌时失败

public static String generateAccessToken(AzureAccount accountValue) throws MalformedURLException, InterruptedException,
                    ExecutionException, ServiceUnavailableException {
        AuthenticationContext context;
        ExecutorService service = null;
        try {
            String tenantId = accountValue.getTenant();
            String ClientID = accountValue.getClient();
            String secretKey = accountValue.getKey();
            service = Executors.newFixedThreadPool(1);
            context = new AuthenticationContext(
                                                "https://login.microsoftonline.de/" + tenantId
                                                + "/oauth2/authorize", false,
                                                service);

            ClientCredential cred = new ClientCredential(ClientID, secretKey);
            Future<AuthenticationResult> future =
                                                context.acquireToken("https://management.microsoftazure.de", cred,
                                                                     null);
            AuthenticationResult authenticationResult = future.get();
            if (authenticationResult == null) {
                throw new ServiceUnavailableException("authentication result was null");
            }
            System.out.println("Bearer " + authenticationResult.getAccessToken());
            return "Bearer " + authenticationResult.getAccessToken();
        }
        finally {
            service.shutdown();
        }
    }

该代码适用于Azure General Cloud,但对于German Cloud失败.

这是stackTrace

看起来它正在寻找一些我不知道的证书文件.有没有人对此有任何想法？

还有一种方法是使用Azure Java SDK获取Azure Access令牌,这样我就不必单独进行REST API调用了吗？

最佳答案 这是因为您使用的是不在德国IP范围内的VM.您有两种选择：

>在Azure德国云或AWS Frankfurt中部署VM
>为了从非德语位置部署：更新您拥有的Java SDK(我有1.8.0_92并更新到1.8.0_144)这应该工作
