方法一，简单的，不计算文字长度去设置脱敏

java 复制代码

public static String dataDesensitization1(String content){
        String regex = "(.{2}).*(.{2})";
        return ReUtil.replaceAll(content, regex, matcher -> {
            try {
                if (CharSequenceUtil.isBlank(matcher.group())) {
                    return "";
                }
                String start = matcher.group(1);
                String end = matcher.group(2);
                return start + "****" + end;
            } catch (Exception e) {
                return "";
            }
        });
    }

方法二，计算长度，取头尾三个文字，其余为**

java 复制代码

return ReUtil.replaceAll(content, "(?<=.{2}).*(?=.{2})", matcher -> {
        try {
            if (CharSequenceUtil.isBlank(matcher.group())) {
                return "";
            }
            String middle = matcher.group();
            String desensitizedMiddle = ""; // 脱敏后的中间部分
            for (int i = 0; i < middle.length(); i++) {
                // 遍历中间部分的每个字符，只保留第一个和最后一个字符，其他用 "*" 代替
                if (i == 0 || i == middle.length() - 1) {
                    desensitizedMiddle += middle.charAt(i);
                } else {
                    desensitizedMiddle += "*";
                }
            }
            return desensitizedMiddle;
        } catch (Exception e) {
            return "";
        }
    });

一些其他的正则

java 复制代码

PHONE = "((13[0-9]|14[01456879]|15[0-35-9]|16[2567]|17[0-8]|18[0-9]|19[0-35-9])\\d{8})";

java 复制代码

ID_CARD_FIFTEEN = "([1-9]\\d{5}\\d{2}((0[1-9])|(10|11|12))(([0-2][1-9])|10|20|30|31)\\d{2}[0-9Xx])";//15位身份证

java 复制代码

ID_CARD_EIGHTEEN = "([1-9]\\d{5}\\d{4}((0[1-9])|(10|11|12))(([0-2][1-9])|10|20|30|31)\\d{3}[0-9Xx])";//18位身份证
