本来想去看看百度地图API有没有根据地址直接获取邮编的功能，结果发现可能百度觉得有利可图便把ZIP的返回结果给去掉了..
因为我的excel表的地址写的不是很规范 ，所以提出了一下思路：
- 先根据excel表中的模糊地址找经纬度
- 根据经纬找到省市县（区）
- 根据省市县区字符串再去百度的邮编爬取邮编
直接贴代码：
/**
* 根据excel中的地址找到经纬度，返回省市县
* @param data
* @return
* @throws IOException
*/
private static List<String> getLocationFromBaidu(data data) throws IOException {
String ak = "你的ak";
String url = "http://api.map.baidu.com/geocoder/v2/";
HTTPParam output = new HTTPParam("output", "json");
HTTPParam Ak = new HTTPParam("ak", ak);
HTTPParam address = new HTTPParam();
String result = "";
List<HTTPParam> params = new ArrayList<HTTPParam>();
params.add(output);
params.add(Ak);
address = new HTTPParam("address", data.getAddress());
params.add(address);
result = HttpSend.sendGet(url, params);
JSONObject getObj = JSONObject.parseObject(result);
String status = getObj.getString("status");
List<String> strings = new ArrayList<String>();
if (status.equals("0")) {
JSONObject res = getObj.getJSONObject("result");
JSONObject location = res.getJSONObject("location");
String lng = location.getString("lng");
String lat = location.getString("lat");
params = new ArrayList<HTTPParam>();
params.add(output);
params.add(Ak);
params.add(new HTTPParam("location", lat + "," + lng));
String result1 = HttpSend.sendGet(url, params);
JSONObject getObj1 = JSONObject.parseObject(result1);
String status1 = getObj1.getString("status");
if (status1.equals("0")) {
JSONObject jsonObject = getObj1.getJSONObject("result");
JSONObject addressComponent = jsonObject.getJSONObject("addressComponent");
strings.add(URLDecoder.decode(addressComponent.getString("province").toString(), "UTF-8"));
strings.add(URLDecoder.decode(addressComponent.getString("city"), "UTF-8"));
strings.add(URLDecoder.decode(addressComponent.getString("district"), "UTF-8"));
strings.add(URLDecoder.decode(addressComponent.getString("street"), "UTF-8"));
return strings;
}

return null;
