Java实现根据地址智能识别省市区县及详细地址Util

目录

一、需求

二、思路

三、实现代码

一、需求

????????根据OCR识别出的身份证地址或者用户输入的地址，智能识别出用户的省、市、区/县和详细地址信息。

二、思路

? ? ? ? 解析给到接口的完整地址fullAddress，逐个匹配省province、市city、区/县area、详细地址detail，然后将 province+city+area+detail 返回即可。

PS：需要考虑一些情况：

1、四个直辖市（北京市、上海市、天津市、重庆市）。直辖市的完整地址fullAddress只有省、县/区

2、完整地址fullAddress只有省、区/县

3、市与区/县重名

4、区/县与区/县重名

三、实现代码
