数据脱敏又称数据去隐私化或数据变形,是在给定的规则、策略下对敏感数据进行变换、修改的技术机制,能够在很大程度上解决敏感数据在非可信环境中使用的问题。根据数据保护规范和脱敏策略.对业务数据中的敏感信息实施自动变形.实现对敏感信息的隐藏。
项目是在controller层进行脱敏,查阅google和github有两种较为方便的方法
新建枚举类型,标明是何种脱敏方式
package com.blgroup.vision.common.enums;
/**
* @program: blgroup-scloud-web
* @description: 脱敏枚举
* @author: ingxx
* @create: 2019-12-17 14:32
**/
public enum SensitiveTypeEnum {
/**
* 中文名
*/
CHINESE_NAME,
/**
* 身份证号
*/
ID_CARD,
/**
* 座机号
*/
FIXED_PHONE,
/**
* 手机号
*/
MOBILE_PHONE,
/**
* 地址
*/
ADDRESS,
/**
* 电子邮件
*/
EMAIL,
/**
* 银行卡
*/
BANK_CARD,
/**
* 虚拟账号
*/
ACCOUNT,
/**
* 密码
*/
PASSWORD;
}
创建注解,标识需要脱敏的字段
package com.blgroup.vision.common.annotation;
import com.blgroup.vision.common.enums.SensitiveTypeEnum;
import java.lang.annotation.*;
/**
* @program: blgroup-scloud-web
* @description: 脱敏注解
* @author: ingxx
* @create: 2019-12-17 14:32
**/
@Target({ElementType.FIELD, ElementType.METHOD})
@Retention(RetentionPolicy.RUNTIME)
@Inherited
@Documented
public @interface Desensitized {
/*脱敏类型(规则)*/
SensitiveTypeEnum type();
/*判断注解是否生效的方法*/
String isEffictiveMethod() default "";
}
创建Object工具类,用于复制对象和对对象的其他操作,注意使用fastjson实现深拷贝对于复杂的对象会出现栈溢出,本人测试是发生在转换对象时对象会转换成JsonObject对象,在getHash
方法中出现递归调用导致栈溢出,具体原因不明

测试主方法
import com.alibaba.fastjson.JSON;
import top.ingxx.pojo.Test;
import top.ingxx.pojo.UserInfo;
import top.ingxx.utils.DesensitizedUtils;
public class Main {
public static void main(String[] args) {

userInfo.setIdCardNo("111521444474441411");
userInfo.setMobileNo("13555551141");
userInfo.setPassword("123456");
userInfo.setRealName("张三");
userInfo.setBankCard("111521444474441411");
Test test = new Test();
test.setUserInfo(userInfo);
System.out.println(JSON.toJSONString(test));
Test obj = DesensitizedUtils.getObj(test);
System.out.println(JSON.toJSONString(obj));
}
}
使用时可以对单个字段脱敏 也可以直接使用 getObj
getJson
getList
等方法
