页面保存为静态页面

UTIl方法：

public class StaticPage {
	/**
	 * 
	 * @param surl
	 * @return
	 */
	public static String getStaticPage(String surl) {
		String htmlContent = "";
		try {
			java.io.InputStream inputStream;
			java.net.URL url = new java.net.URL(surl);
			java.net.HttpURLConnection connection = (java.net.HttpURLConnection) url
					.openConnection();
			connection.connect();
			inputStream = connection.getInputStream();
			byte bytes[] = new byte[1024 * 2000];
			int index = 0;
			int count = inputStream.read(bytes, index, 1024 * 2000);
			while (count != -1) {
				index += count;
				count = inputStream.read(bytes, index, 1);
			}
			htmlContent = new String(bytes, "gb2312");
			connection.disconnect();
		} catch (Exception ex) {
			ex.printStackTrace();
		}
		return htmlContent.trim();
	}

	/**
	 * 
	 * @param url
	 * @return
	 */
	public static String getHtmlSource(String url) {
		StringBuffer codeBuffer = null;
		BufferedReader in = null;
		try {
			URLConnection uc = new URL(url).openConnection();
			// 读取url流内容
			in = new BufferedReader(new InputStreamReader(uc.getInputStream(),
					"gb2312"));
			codeBuffer = new StringBuffer();
			String tempCode = "";
			// 把buffer内的值读取出来
			while ((tempCode = in.readLine()) != null) {
				codeBuffer.append(tempCode).append("\n");
			}
			in.close();
		} catch (Exception e) {
			e.printStackTrace();
		}

		return codeBuffer.toString();
	}

	/**
	 * 
	 * @param url
	 * @return
	 */
	public static String getHtmlPage(String url) {
		StringBuffer codeBuffer = null;
		BufferedReader in = null;
		HttpURLConnection conn = null;
		try {
			URL uUrl = new URL(url);
			conn = (HttpURLConnection) uUrl.openConnection();
			conn.setRequestProperty("Accept-Charset", "utf-8");
			conn.setRequestProperty("contentType", "utf-8");

			BufferedReader reader = new BufferedReader(new InputStreamReader(
					conn.getInputStream(), "gbk"));
			String downloadURL;
			codeBuffer = new StringBuffer();
			while ((downloadURL = reader.readLine()) != null) {
				codeBuffer.append(downloadURL);
			}
		} catch (Exception e) {
			e.printStackTrace();
		}
		return codeBuffer.toString();
	}
}

生成HTML静态页面

public String staticPage() {
		String page = (String) ac.getData("page");
		String url = (String) ac.getData("url");
		try {
//			String sPage = StaticPage.getStaticPage(url);
//			String sPage = StaticPage.getHtmlSource(url); 
			String sPage = StaticPage.getHtmlPage(url); 
			File file = new File("d:/HTML/"+page+".html");
			FileWriter resultFile = new FileWriter(file);
			PrintWriter myFile = new PrintWriter(resultFile);
			// 写文件
			myFile.println(sPage);
			resultFile.close();
			myFile.close();
		} catch (Exception e) {
			e.printStackTrace();
		}
		return "success";
	}

方法保存静态页面的缺点，无法保存图片，还希望知道更好方法的能提供更好的方法，谢谢！
