javafx做的天气预报小程序

javafx做的天气预报小程序:

数据来源于中央天象台提供的api 。处理的是Json数据，可以播报6天的天气。

天气的数据来源中央气象台. http://m.weather.com.cn/data/101200101.html 其中 101200101 为武汉的城市代码。通过这个网站获取json数据，然后解析json数据，提取相应的天气信息。

1. 软件只添加了几个城市，大家如果有好的方法能够将全国的城市（精确到县一级）都添加进去，希望提提意见。将全国的城市代码都加到CityList.XML文件中不是个好方法......

2. 另外，通过ip显示当前城市，然后显示当前城市的天气这个时灵时不灵（可能是我这网络的原因，获取ip的网站有时不能访问）。通过访问网站 http://61.4.185.48:81/g/ 得到本机访问的IP，根据此IP查询到城市ID。

效果图:

Json数据解析代码:

public Weather(String Cityid) throws IOException, NullPointerException {
		// 解析本机ip地址

		this.Ctiyid = Cityid;
		// 连接中央气象台的API
		URL url = new URL("http://m.weather.com.cn/data/" + Ctiyid + ".html");
		connectionData = url.openConnection();
		connectionData.setConnectTimeout(1000);
		try {
			br = new BufferedReader(new InputStreamReader(
					connectionData.getInputStream(), "UTF-8"));
			sb = new StringBuilder();
			String line = null;
			while ((line = br.readLine()) != null)
				sb.append(line);
		} catch (SocketTimeoutException e) {
			System.out.println("亲，网络没有连接");
		} catch (FileNotFoundException e) {
			System.out.println("亲，网络没有连接");
		}

		jsonData = JSONObject.fromObject(sb.toString());
		weatherinfo = jsonData.getJSONObject("weatherinfo");
