Тайм-аут соединения для шаблона отдыха с HTTP-клиентом 4.5 под прокси

Как установить тайм-аут? Я установил почти все конфигурации тайм-аута. Обычно без прокси работает нормально. Проблема возникает, когда я соединяюсь с прокси-данными соединения. Журнал показывает, что он подключается и ответ не получен.

Вот мой конфиг. Я использую пружинный ботинок 2.2. 

PoolingHttpClientConnectionManager connectionManager;
if (properties.isAllCertificateAllowed()) {
  connectionManager =
          new PoolingHttpClientConnectionManager(
                  buildSocketFactoryRegistry(trustAllSslConnectionSocketFactory(trustAllSslContext())));
} else {
  connectionManager = new PoolingHttpClientConnectionManager();
}

RequestConfig config = RequestConfig.custom()
        .setSocketTimeout(properties.getConnectTimeout())
        .setConnectTimeout(properties.getConnectTimeout())
        .setConnectionRequestTimeout(properties.getConnectTimeout())
        .build();

/* HttpClientBuilder using http client connection connectionManager */
HttpClientBuilder httpClientBuilder =
        HttpClientBuilder.create()
                .setConnectionManager(connectionManager)
                .useSystemProperties()
                .disableCookieManagement()
                .setDefaultRequestConfig(config);

HttpComponentsClientHttpRequestFactory httpRequestFactory = new HttpComponentsClientHttpRequestFactory();
httpRequestFactory.setConnectTimeout(properties.getConnectTimeout()) ;
httpRequestFactory.setReadTimeout(properties.getReadTimeout());
httpRequestFactory.setConnectionRequestTimeout(properties.getConnectionRequestTimeout());

if (properties.isProxyEnabled()) {
  log.info(properties.toString());

  /* proxy username ,password name setting */
  CredentialsProvider credentialsProvider = new BasicCredentialsProvider();
  credentialsProvider.setCredentials(
          new AuthScope(properties.getProxyAddress(), properties.getProxyPort()),
          new UsernamePasswordCredentials(
                  properties.getProxyUsername(), properties.getProxyPassword()));

  httpClientBuilder.setProxy(
          new HttpHost(properties.getProxyAddress(), properties.getProxyPort())); //TODO,"https"
  httpClientBuilder.setDefaultCredentialsProvider(credentialsProvider);

  CloseableHttpClient httpClient = httpClientBuilder.build();
  httpRequestFactory.setHttpClient(httpClient);
}
RestTemplate restTemplate = new RestTemplate(httpRequestFactory);

Похоже, проблема с прокси. Схема HTTP / HTTPS конфигурации прокси должна быть проверена с указанными вами данными прокси. Вы можете дать возможность доверять всем сертификатам при создании restTemplate. См. Пример ниже для доверия всем сертификатам: -

      connectionManager = new PoolingHttpClientConnectionManager();

    connectionManager.setMaxTotal(properties.getMaxPooledHttpConnections());
    connectionManager.setDefaultMaxPerRoute(properties.getMaxHttpConnectionsPerRoute());
