1、高德地图api调用接口说明文档：https://lbs.amap.com/api/webservice/guide/api/district/#limit
具体数据接口：
https://restapi.amap.com/v3/config/district?subdistrict=4&key=bb4198a1f146184af53322d424732f6b
注意：如果想调用此接口需要申请一个key,免费的，注册就可以获取
2、我的码云代码：https://gitee.com/liran123/yft-evidence
3、java代码如下：
@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();
//数据结构如下
/* String jsonString = "{n" +

注意：第一次调用接口解析的省市区不是按顺序解析，需要调用排序接口重新生成。最后看排序后的 region_order 表就可以
