将动态页面转换成静态页面

  public static void main(String[] args) throws IOException {
    	java.net.URL url = new java.net.URL("http://www.baidu.com");
    	   HttpURLConnection connection = (java.net.HttpURLConnection) url.openConnection();
    	   connection.connect();
    	   InputStream urlStream;
    	   urlStream = connection.getInputStream();
    	   BufferedReader reader;
    	   String strLine = "";
    	   String strPage = "";
    	   FileWriter file = null;
    	   reader = new java.io.BufferedReader(
    	     new java.io.InputStreamReader(urlStream,"GB2312"));
    	   while ((strLine = reader.readLine()) != null)
    	    strPage += strLine + "\n";
    	   System.out.println(strPage);
    	   
    	   file = new java.io.FileWriter("D:\\a.html");
    	   file.write(strPage);
