这对我来说非常有效：
package weather;import org.dom4j.document;import org.dom4j.io.OutputFormat;import org.dom4j.io.SAXReader;import org.dom4j.io.XMLWriter;import java.io.BufferedReader;import java.io.InputStreamReader;import java.net.URL;public class GoogleWeather{ public static void main(String[] args) { for (String userZip : args) { BufferedReader br = null; try { String link = "http://www.google.com/ig/api?weather=" + userZip; System.out.println(link); URL googleWeatherService = new URL(link); br = new BufferedReader(new InputStreamReader(googleWeatherService.openStream())); SAXReader reader = new SAXReader(); document document = reader.read(googleWeatherService); OutputFormat format = OutputFormat.createPrettyPrint(); XMLWriter writer = new XMLWriter(System.out, format); writer.write(document); } catch (Exception e) { e.printStackTrace(); } finally { close(br); } } } private static void close(BufferedReader br) { try { if (br != null) { br.close(); } } catch (Exception e) { e.printStackTrace(); } }}这是它带来的结果：
