说明

  • 将中华人民共和国的地址脱敏到第二级（不一定是地区级）
  • 中华人民共和国的地区级行政区划分为四种：地级市、地区、盟、自治州
  • 地址脱敏思路如下
    • 找到【盟】
    • 找到【自治州】
    • 找到【地区】
    • 找到【市】
      • 如果是【地级市】即可结束
      • 如果是【直辖市】则找到下一级的【区】或【县】
    • 如果均不符合则脱敏2/3的地址（包括英文）
  • 使用到了cn.hutool.core.util.StrUtil

实现

  • Utils.java类

    package org.example;

/**
 * @author Histone Von histonevon@zohomail.com
 * @createdBy Histone Von
 * @date 2023/7/9 14:15
 */

public class Utils {
    /**
     * 返回子串在母串中最后一个字符的索引
     * @param str 母串
     * @param subStr 子串
     * @return int 子串最后一个字符的索引，错误返回-2，未找到返回-1
     */
    public static int strStr(String str, String subStr) {
        int index = -2;
        if (!StrUtil.isBlank(str) && !StrUtil.isBlank(subStr)) {
            index = str.indexOf(subStr);
            if (index != -1) {
                index += subStr.length() - 1;
            }
        }
        return index;
    }
}

  • AddressDesensitization.java类：传入地址，返回脱敏后地址

    package org.example;

import cn.hutool.core.util.StrUtil;

/**

 * @createdBy Histone Von
 * @date 2023/7/9 14:28
 */

public class AddressDesensitization {
    public static String desensitize(String address) {
        if (StrUtil.isBlank(address)) {
            return "";
        } else {
            String addressDesensitized;
            if (Utils.strStr(address, "盟") >= 0) { // 1.盟
                addressDesensitized = StrUtil.hide(address, Utils.strStr(address, "盟") + 1, address.length());
            } else if (Utils.strStr(address, "自治州") >= 0) { // 2.自治州
                addressDesensitized = StrUtil.hide(address, Utils.strStr(address, "自治州") + 1, address.length());
            } else if (Utils.strStr(address, "地区") >= 0) { // 3.地区
                addressDesensitized = StrUtil.hide(address, Utils.strStr(address, "地区") + 1, address.length());
            } else if (Utils.strStr(address, "市") >= 0) { // 4.市
                boolean isBeijing = address.contains("北京"); // 4-1.排除直辖市
                boolean isShanghai = address.contains("上海");
                boolean isTianjin = address.contains("天津");
                boolean isChongqing = address.contains("重庆");
                if (!isBeijing && !isShanghai && !isTianjin && !isChongqing) { // 4-2.地级市
                    addressDesensitized = StrUtil.hide(address, Utils.strStr(address, "市") + 1, address.length());
                } else { // 4-3.直辖市查区县
                    int indexDistrictOrCounty; // 直辖市的区或者县
                    if (Utils.strStr(address, "区") >= 0) {
                        indexDistrictOrCounty = Utils.strStr(address, "区");
                    } else if (Utils.strStr(address, "县") >= 0) {
                        indexDistrictOrCounty = Utils.strStr(address, "县");
                    } else {
                        indexDistrictOrCounty = 3; // 从下标3的字符开始脱敏，直辖市都是三个字的
                    }
                    addressDesensitized = StrUtil.hide(address, indexDistrictOrCounty + 1, address.length());
                }
            } else { // 5.其余的脱敏2/3
                addressDesensitized = StrUtil.hide(address, address.length() / 3, address.length());
            }
            return addressDesensitized;
        }
    }
}

运行示例

        System.out.println(AddressDesensitization.desensitize("浙江省宁波市江北区同济路280弄155号"));
        System.out.println(AddressDesensitization.desensitize(""));
        System.out.println(AddressDesensitization.desensitize("内蒙古自治区锡林郭勒盟二连浩特市格日勒敖都苏木"));
        System.out.println(AddressDesensitization.desensitize("吉林省延边朝鲜族自治州延吉市依兰镇"));
        System.out.println(AddressDesensitization.desensitize("新疆维吾尔自治区阿勒泰地区阿勒泰市解放路街道"));
        System.out.println(AddressDesensitization.desensitize("北京市海淀区中关村街道"));
        System.out.println(AddressDesensitization.desensitize("上海市浦东新区陆家嘴街道"));
        System.out.println(AddressDesensitization.desensitize("重庆市酉阳土家族苗族自治县中和街道"));
        System.out.println(AddressDesensitization.desensitize("香港特别行政区湾仔区铜锣湾"));
        System.out.println(AddressDesensitization.desensitize("No. 7, Section 5, Xinyi Road, Xinyi District, Taipei"));
    }
}
