那代理IP 从哪里搞呢 很简单 百度一下，你就知道 一大堆代理IP站点。 一般都会给出一些免费的，但是花点钱搞收费接口更加方便；
比如 http://www.66ip.cn/

RequestConfig requestConfig=RequestConfig.custom().setProxy(proxy).build();
httpGet.setConfig(requestConfig);
httpGet.setHeader(

,
"Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:50.0) Gecko/20100101 Firefox/50.0"
);
CloseableHttpResponse response=httpClient.execute(httpGet);
// 执行http get请求
HttpEntity entity=response.getEntity();
// 获取返回实体
System.out.println(
"网页内容："
+EntityUtils.toString(entity,
"utf-8"
));
// 获取网页内容
response.close();
// response关闭
httpClient.close();
// httpClient关闭
}
}
