httpClient如何设置代理

public static void main(String args[])
{
 StringBuffer sb = new StringBuffer();
 //创建HttpClient实例
 HttpClient client = getHttpClient();
 //创建httpGet
 HttpGet httpGet = new HttpGet("http://www.csdn.net");
 //执行
 try {
  HttpResponse response = client.execute(httpGet);
  
  HttpEntity entry = response.getEntity();
  
  if(entry != null)
  {
   InputStreamReader is = new InputStreamReader(entry.getContent());
   BufferedReader br = new BufferedReader(is);
   String str = null;
   while((str = br.readLine()) != null)
   {
    sb.append(str.trim());
   }
   br.close();
  }
  
 } catch (ClientProtocolException e) {
  // TODO Auto-generated catch block
  e.printStackTrace();
 } catch (IOException e) {
  // TODO Auto-generated catch block
  e.printStackTrace();
 }
 System.out.println(sb.toString());
}

//设置代理

public static HttpClient getHttpClient() {

 DefaultHttpClient httpClient = new DefaultHttpClient();
 String proxyHost = "proxycn2.huawei.com";
 int proxyPort = 8080;
 String userName = "china\\******";
 String password = "*******“
 httpClient.getCredentialsProvider().setCredentials(
   new AuthScope(proxyHost, proxyPort),
   new UsernamePasswordCredentials(userName, password));
 HttpHost proxy = new HttpHost(proxyHost,proxyPort);
 httpClient.getParams().setParameter(ConnRouteParams.DEFAULT_PROXY, proxy);
 return httpClient;
}
