Java实现根据地址智能识别省市区县
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+deta编程客栈il 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
