利用百度天气提供的接口，申请了一个key：
关键代码：

//主机String httpUrl = "http://apis.baidu.com/apistore/weatherservice/recentweathers";//参数String httpArg = "cityname=%E5%8C%97%E4%BA%AC&cityid=101010100";String jsonResult = request(httpUrl, httpArg);System.out.println(jsonResult);/** * @param urlAll *            :请求接口 * @param httpArg *            :参数 * @return 返回结果 */public static String request(String httpUrl, String httpArg) {    BufferedReader reader = null;    String result = null;    StringBuffer sbf = new StringBuffer();    httpUrl = httpUrl + "?" + httpArg;    try {        URL url = new URL(httpUrl);        HttpURLConnection connection = (HttpURLConnection) url                .openConnection();        connection.setRequestMethod("GET");        // 填入apikey到HTTP header        connection.setRequestProperty("apikey",  "您自己的apikey");        connection.connect();        InputStream is = connection.getInputStream();        reader = new BufferedReader(new InputStreamReader(is, "UTF-8"));        String strRead = null;        while ((strRead = reader.readLine()) != null) {            sbf.append(strRead);            sbf.append("\r\n");        }        reader.close();        result = sbf.toString();    } catch (Exception e) {        e.printStackTrace();    }    return result;}

因为是网络请求数据，要另外开一个线程Thread，我就卡了半天在这里！故提醒大家一下。

本人做了一个例子，希望对大家有所帮助
