Android Spring RestTemplate with Proxy

Question

我需要从手机上读取代理信息，如果手机在代理下，我需要在我的spring restTemplate对象上设置这个代理。我试过下面的代码没有任何运气，谁能告诉我我做错了什么。

String proxyHost = android.net.Proxy.getHost(activity
            .getApplicationContext());
SimpleClientHttpRequestFactory requestFactory = new SimpleClientHttpRequestFactory();
Proxy proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress(proxyHost, 8080));
requestFactory.setProxy(proxy);
RestTemplate rest = new RestTemplate(requestFactory);

感谢您的帮助

我找到了我问题的答案。将在这里发布代码:

 if (proxyHost != null && proxyPort != null) {
        rest = new RestTemplate();
        HttpComponentsClientHttpRequestFactory factory =   ((HttpComponentsClientHttpRequestFactory) rest
                .getRequestFactory());
        DefaultHttpClient defaultHttpClient = (DefaultHttpClient) factory
                .getHttpClient();
        HttpHost proxy = new HttpHost(proxyHost, proxyPort);
        defaultHttpClient.getParams().setParameter(
                ConnRoutePNames.DEFAULT_PROXY, proxy);
    } else {
        rest = new RestTemplate();
        HttpComponentsClientHttpRequestFactory factory = ((HttpComponentsClientHttpRequestFactory) rest
                .getRequestFactory());
        DefaultHttpClient defaultHttpClient = (DefaultHttpClient) factory
                .getHttpClient();
    }
