需求：通过高德api查询所有店铺地址信息

需求分析

查询现有高德api发现现有接口关键字搜索API服务地址：

https://developer.amap.com/api/webservice/guide/api/search
参数需要主要参数：key、types、city
其中types city可以查询：
https://developer.amap.com/api/webservice/download

具体实现

1、申请高德appkey

地址：https://console.amap.com/dev/key/app

2、下载types city 字典值

并将字典值解析读取到代码中，如图

3、具体代码调用

类说明：

Api  调用方法
CityUtil 城市编码查询工具类
ReaderFile 文件读写工具类
Shop 地点实体类
ShopUtil 地点查询工具类
