我想使用ResteasyClient访问电源Bi中的组列表，身份验证的形式我想使用服务主体（仅应用程序令牌）。我有应用程序ID（客户端），应用程序秘密（密钥）范围= Group.Read.All，访问令牌URL https://login.microsoftonline.com/common/oauth2/token和授予类型=客户端凭据。

public static String getAccessToken(OAuth2Details oauthDetails) {
    HttpPost post = new HttpPost(oauthDetails.getAuthenticationServerUrl());
        String clientId = oauthDetails.getClientId();
        String clientSecret = oauthDetails.getClientSecret();
        String scope = oauthDetails.getScope();

        List<BasicNameValuePair> parametersBody = new ArrayList<BasicNameValuePair>();
        parametersBody.add(new BasicNameValuePair(OAuthConstants.GRANT_TYPE,
                oauthDetails.getGrantType()));

        parametersBody.add(new BasicNameValuePair(OAuthConstants.CLIENT_ID,
                clientId));

        parametersBody.add(new BasicNameValuePair(
                OAuthConstants.CLIENT_SECRET, clientSecret));

        if (isValid(scope)) {
            parametersBody.add(new BasicNameValuePair(OAuthConstants.SCOPE,
                    scope));
        }

        HttpClient client = new DefaultHttpClient();
        HttpResponse response = null;
        String accessToken = null;
        try {
            post.setEntity(new UrlEncodedFormEntity(parametersBody, HTTP.UTF_8));
            response = client.execute(post);
            int code = response.getStatusLine().getStatusCode();
            if (code == OAuthConstants.HTTP_UNAUTHORIZED) {
                if …
