字符脱敏工具类

1、字符脱敏工具类

import lombok.extern.slf4j.Slf4j;
import org.apache.commons.lang3.StringUtils;/*** 数据脱敏工具类** @date 2024/10/30 13:44*/@Slf4j
public class DataDesensitizationUtils {public static final String STAR_1 = "*";public static final String STAR_2 = "**";public static final String STAR_3 = "***";public static final String STAR_4 = "****";/*** 手机号脱敏** @param mobile 手机号* @return 返回值*/public static String mobileDesensitize(String mobile) {// 如果手机号为空则返回空字符串if (StringUtils.isBlank(mobile)) {return "";}// 取手机号最后4位String right = StringUtils.right(mobile, 4);// 手机号除了最后4位都用*代替String leftPad = StringUtils.leftPad(right, StringUtils.length(mobile), STAR_1);// 移除前面默认的三位*String removeStart = StringUtils.removeStart(leftPad, STAR_3);// 取手机号前3位String left = StringUtils.left(mobile, 3);// 字符串链接并返回return left.concat(removeStart);}/*** 姓名脱敏** @param name 姓名* @return 返回值*/public static String nameDesensitize(String name) {// 名字为空则返回空字符串if (StringUtils.isBlank(name)) {return "";}// 名字长度小于等于3个字符，则将前面一个字符用*代替int length = 3;if (name.length() <= length) {int len = name.length() - 1;String right = StringUtils.right(name, len);return STAR_1.concat(right);}// 名字长度大于3个字符，则将前两个字符用*代替int len = name.length() - 2;String right = StringUtils.right(name, len);return STAR_2.concat(right);}/*** 地址脱敏** @param detailAddress 地址* @return 返回值*/public static String detailAddressDesensitize(String detailAddress) {int length = 10;String desensitizationText = STAR_4;// 地址为空或长度小于10个字符则默认返回*if (StringUtils.isBlank(detailAddress) || detailAddress.length() <= length) {return desensitizationText;} else {// 把地址10个字符后的所有字符替换为*StringBuilder address = new StringBuilder(detailAddress);int start = address.length() - 10;int end = address.length();return address.replace(start, end, desensitizationText).toString();}}}

2、测试工具类

@Slf4j
@ExtendWith(MockitoExtension.class)
public class DataDesensitizationUtilsTest {@Testpublic void testMobileDesensitize() {String mobile = "13011112222";String result = DataDesensitizationUtils.mobileDesensitize(mobile);log.info("手机号脱敏结果：{}", result);}@Testpublic void testNameDesensitize() {String name = "诸葛孔明";String result = DataDesensitizationUtils.nameDesensitize(name);log.info("姓名脱敏结果：{}", result);}@Testpublic void testAddressDesensitize() {String address = "北京首钢国际会展中心9号馆、10号馆";String result = DataDesensitizationUtils.detailAddressDesensitize(address);log.info("地址脱敏结果：{}", result);}}
