前言： 最近項目中用到了全國省市區三級信息，但是網上找到的信息都是比較舊的信息。與現在最新的地區信息匹配不上。後來想到高德地圖上可能有這些信息。所以解析了一下api介面，生成了相關省市區的sql信息。（註意：這裡面沒有港臺地區）具體的請參看高德地圖文檔。 alibaba.fastjson解析+mys ...
前言：
最近項目中用到了全國省市區三級信息，但是網上找到的信息都是比較舊的信息。與現在最新的地區信息匹配不上。後來想到高德地圖上可能有這些信息。所以解析了一下api介面，生成了相關省市區的sql信息。（註意：這裡面沒有港臺地區）具體的請參看高德地圖文檔。
alibaba.fastjson解析+mysql表
1、高德地圖api調用介面說明文檔：https://lbs.amap.com/api/webservice/guide/api/district/#limit
具體數據介面：
https://restapi.amap.com/v3/config/district?subdistrict=4&key=bb4198a1f146184af53322d424732f6b
註意：如果想調用此介面需要申請一個key,免費的，註冊就可以獲取
2、我的碼雲代碼：https://gitee.com/liran123/yft-evidence
3、java代碼如下：
@RequestMapping("/getAll")
public Object getMasterList() throws Exception {
HttpClientResult result = HttpClientUtils.doGet("https://restapi.amap.com/v3/config/district?subdistrict=4&key=bb4198a1f146184af53322d424732f6b");
String jsonString = result.getContent();

註意：第一次調用介面解析的省市區不是按順序解析，需要調用排序介面重新生成。最後看排序後的 region_order 表就可以
