OAuth谷歌API用于Java无法冒充用户

我想模仿一个用户，并代表他们代表服务器进程向用户添加文件。我已经设置了服务帐户，并可以成功访问驱动器作为服务帐户添加和列出文件等。使用以下代码： 

  /** Global instance of the HTTP transport. */
  private static final HttpTransport HTTP_TRANSPORT = new NetHttpTransport();

  /** Global instance of the JSON factory. */
  private static final JsonFactory JSON_FACTORY = new JacksonFactory();

  public static void main(String[] args) {
    try {
        GoogleCredential credential = 
                new GoogleCredential.Builder().setTransport(HTTP_TRANSPORT)
                  .setJsonFactory(JSON_FACTORY)
                  .setServiceAccountId("XXXXX@developer.gserviceaccount.com")
                  .setServiceAccountScopes(DriveScopes.DRIVE)
                  .setServiceAccountPrivateKeyFromP12File(new File("c:/junk/key.p12"))
                  .build();
        Drive drive = new Drive.Builder(HTTP_TRANSPORT, JSON_FACTORY, credential).build();         
        drive.files().list().execute();
  } catch (Exception e) {
     e.printStackTrace();
  }
.

此工作，但只返回与我假设关联的文件与服务帐户驱动器（？）相关联。

根据javadoc，Googlecredential也可用于通过添加服务帐户用户电子邮件地址来模拟用户，如下所示： 

        GoogleCredential credential = 
                new GoogleCredential.Builder().setTransport(HTTP_TRANSPORT)
                  .setJsonFactory(JSON_FACTORY)
                  .setServiceAccountId("XXXXX@developer.gserviceaccount.com")
                  .setServiceAccountScopes(DriveScopes.DRIVE)
                  .setServiceAccountPrivateKeyFromP12File(new File("c:/junk/key.p12"))
                  .setServiceAccountUser("usera@domain.com") //<-- impersonate user a
                  .build();
. 但是，在执行此代码时，抛出以下异常： 
com.google.api.client.auth.oauth2.TokenResponseException: 400 Bad Request
{
  "error" : "access_denied"
}
at com.google.api.client.auth.oauth2.TokenResponseException.from(TokenResponseException.java:103)

at com.google.api.client.http.json.JsonHttpRequest.executeUnparsed(JsonHttpRequest.java:207)

.

我缺少一步或配置设置？

谢谢， 大卫
