我正在尝试使用服务帐户方法访问Google BigQuery .我的代码如下:

private static final HttpTransport HTTP_TRANSPORT = new NetHttpTransport();

private static final JsonFactory JSON_FACTORY = new JacksonFactory();

GoogleCredential credentials = new GoogleCredential.Builder()
            .setTransport(HTTP_TRANSPORT)
            .setJsonFactory(JSON_FACTORY)
            .setServiceAccountId("XXXXX@developer.gserviceaccount.com")
            .setServiceAccountScopes(BigqueryScopes.BIGQUERY)
            .setServiceAccountPrivateKeyFromP12File(
                    new File("PATH-TO-privatekey.p12"))
            .build();
    Bigquery bigquery = Bigquery.builder(HTTP_TRANSPORT, JSON_FACTORY).setHttpRequestInitializer(credentials)
            .build();
    com.google.api.services.bigquery.Bigquery.Datasets.List datasetRequest = bigquery.datasets().list(
            "PROJECT_ID");

    DatasetList datasetList = datasetRequest.execute();
    if (datasetList.getDatasets() != null) {
        java.util.List<Datasets> datasets = datasetList.getDatasets();
        System.out.println("Available datasets\n----------------");
        for (Datasets dataset : datasets) {
            System.out.format("%s\n", dataset.getDatasetReference().getDatasetId());
        }
    }

但它抛出以下异常:

Exception in thread "main"  com.google.api.client.googleapis.json.GoogleJsonResponseException: 401 Unauthorized
