使用正则进行中文地址解析（结构化解析）

## Java正则--地址结构化解析

```java
    public static Map<String, String> addressResolution(String address) {
        String regex = "(?<province>.*?自治区|.*?省|.*?行政区|.*?市)(?<city>.*?自治州|.*?地区|.*?行政单位|市辖区|.*?市)?(?<county>.*?市|.*?县|.*?区)?(?<village>.*)";
        Matcher m = Pattern.compile(regex).matcher(address);
        String province, city, county, village;
        Map<String, String> row = null;
        while (m.find()) {
            row = new LinkedHashMap<>();
            province = StringUtils.isNotBlank(m.group("province")) ? m.group("province").trim() : "";
            row.put("province", StringUtils.isEmpty(province) ? address : province);
            city = StringUtils.isNotBlank(m.group("city")) ? m.group("city").trim() : "";
            row.put("city", StringUtils.isEmpty(city) ? province : city);
            county = StringUtils.isNotBlank(m.group("county")) ? m.group("county").trim() : "";
            row.put("county", StringUtils.isEmpty(county) ? city : county);
            village = StringUtils.isNotBlank(m.group("village")) ? m.group("village").trim() : "";
            row.put("village", StringUtils.isEmpty(village) ? county : village);
        }
        if (row == null) {
            row = new LinkedHashMap<>();
            row.put("village", address);
        }
        return row;
    }

    public static void main(String[] args) {
        System.out.println(addressResolution("山东省潍坊市昌邑市龙源国际小区"));
    }
