java.net.SocketException: Connection reset问题

抓取网页的时候出现这个问题该怎么解决。

// 将URL中的HTML代码下载至本地硬盘 public static void downloadPageContent(String urlStr) throws FileNotFoundException, UnsupportedEncodingException { int aStatus = 200; HttpClient httpclient = new DefaultHttpClient(); HttpGet httpget = new HttpGet(urlStr); HttpResponse response = null; try { response = httpclient.execute(httpget); } catch (ClientProtocolException e) { System.out.println("出错啦。这里"); // e.printStackTrace(); } catch (IOException e) { System.out.println("222"); if(e instanceof org.apache.http.conn.HttpHostConnectException) { System.out.println("拒绝链接，应该换IP尝试代理"); aStatus = 402; } if (e instanceof java.net.UnknownHostException) { System.out.println("找不到主机错误发生，处理异常中"); aStatus = 402; } aStatus = 402; } if (aStatus != 402) { System.out.println(response.getStatusLine().getStatusCode()); HttpEntity entity = response.getEntity(); // 如果目录不存在，则创建文件目录 File file = new File(DirectoryPath); if (!file.exists()) file.mkdirs();// 创建文件 FileOutputStream os = new FileOutputStream(DirectoryPath + URLEncoder.encode(urlStr, "utf-8")); if (entity != null) { InputStream instream = null; try { instream = entity.getContent(); } catch (IllegalStateException e) { System.out.println("出错啦。！"); // TODO Auto-generated catch block e.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } @SuppressWarnings("unused") int l; byte[] tmp = new byte[2048]; try { while ((l = instream.read(tmp)) != -1) { os.write(tmp, 0, tmp.length); } } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } try { os.close(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } }
public static void main(String[] args) throws Exception { long startTime = System.currentTimeMillis(); System.out.println(startTime); <span style="white-space:pre"> </span>downloadPageContent(“http://www.pooioo.com”); long endTime = System.currentTimeMillis(); System.out.println(endTime); System.out.println(endTime-startTime); }
链接重置。我该怎么办呢
