方法一,简单的,不计算文字长度去设置脱敏
java
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
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
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
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
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
