            e.printStackTrace();
            throw new MalformedURLException("URL is malformed!!");

使用JSoup：

public class Main {

    public static void main(final String[] args) throws IOException {
        System.out.println(readFromWeb("http://www.stackoverflow.com/"));
    }

    public static String readFromWeb(final String webUrl) throws IOException {
        final Document doc = Jsoup.connect(webUrl).get();
        return doc.text();
    }
}
