数据脱敏的 3 种常见方案 1.SQL数据脱敏实现MYSQL(电话号码,身份证)数据脱敏的实现-- CONCAT()、LEFT()和RIGHT()字符串函数组合使用，请看下面具体实现 -- CONCAT(str1,str2,…)：返回结果为连接参数产生的字符串 -- LEFT(str,len)：返回从字符串str 开始的len 最左字符 -- RIGHT(str,len)：从字符串str 开始，返回最右len 字符 -- 电话号码脱敏sql： SELECT mobilePhone AS 脱敏前电话号码,CONCAT(LEFT(mobilePhone,3), '********' ) AS 脱敏后电话号码 FROM t_s_user -- 身份证号码脱敏sql: SELECT idcard AS 未脱敏身份证, CONCAT(LEFT(idcard,3), '****' ,RIGHT(idcard,4)) AS 脱敏后身份证号 FROM t_s_user2.JAVA数据脱敏实现可参考：海强 / sensitive-plus{callout color="#f0ad4e"}https://gitee.com/strong_sea/sensitive-plus{/callout}数据脱敏插件，目前支持地址脱敏、银行卡号脱敏、中文姓名脱敏、固话脱敏、身份证号脱敏、手机号脱敏、密码脱敏 一个是正则脱敏、另外一个根据显示长度脱敏，默认是正则脱敏，可以根据自己的需要配置自己的规则。3.mybatis-mate-sensitive-jacksonmybatisplus 的新作，可以测试使用，生产需要收费。根据定义的策略类型，对数据进行脱敏，当然策略可以自定义。# 目前已有 package mybatis.mate.strategy; public interface SensitiveType { String chineseName = "chineseName"; String idCard = "idCard"; String phone = "phone"; String mobile = "mobile"; String address = "address"; String email = "email"; String bankCard = "bankCard"; String password = "password"; String carNumber = "carNumber"; }Demo 代码目录 Spring Boot 基础就不介绍了，推荐看这个免费教程：{callout color="#f0ad4e"}https://github.com/javastacks/spring-boot-best-practice{/callout}1、pom.xml<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <parent> <groupId>com.baomidou</groupId> <artifactId>mybatis-mate-examples</artifactId> <version>0.0.1-SNAPSHOT</version> </parent> <modelVersion>4.0.0</modelVersion> <artifactId>mybatis-mate-sensitive-jackson</artifactId> <dependencies> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> </dependency> </dependencies> </project>2、appliation.yml# DataSource Config spring: datasource: # driver-class-name: org.h2.Driver # schema: classpath:db/schema-h2.sql # data: classpath:db/data-h2.sql # url: jdbc:h2:mem:test # username: root # password: test driver-class-name: com.mysql.cj.jdbc.Driver url: jdbc:mysql://localhost:3306/mybatis_mate?useSSL=false&useUnicode=true&characterEncoding=UTF-8&serverTimezone=UTC username: root password: 123456 # Mybatis Mate 配置 mybatis-mate: cert: # 请添加微信wx153666购买授权，不白嫖从我做起！ 测试证书会失效，请勿正式环境使用 grant: thisIsTestLicense license: as/bsBaSVrsA9FfjC/N77ruEt2/QZDrW+MHETNuEuZBra5mlaXZU+DE1ZvF8UjzlLCpH3TFVH3WPV+Ya7Ugiz1Rx4wSh/FK6Ug9lhos7rnsNaRB/+mR30aXqtlLt4dAmLAOCT56r9mikW+t1DDJY8TVhERWMjEipbqGO9oe1fqYCegCEX8tVCpToKr5J1g1V86mNsNnEGXujnLlEw9jBTrGxAyQroD7Ns1Dhwz1K4Y188mvmRQp9t7OYrpgsC7N9CXq1s1c2GtvfItHArkqHE4oDrhaPjpbMjFWLI5/XqZDtW3D+AVcH7pTcYZn6vzFfDZEmfDFV5fQlT3Rc+GENEg== # Logger Config logging: level: mybatis.mate: debug3、Appliation启动类package mybatis.mate.sensitive.jackson; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; @SpringBootApplication public class SensitiveJacksonApplication { // 测试访问 http://localhost:8080/info ，http://localhost:8080/list public static void main(String[] args) { SpringApplication.run(SensitiveJacksonApplication.class, args); } }4、配置类，自定义脱敏策略package mybatis.mate.sensitive.jackson.config; import mybatis.mate.databind.ISensitiveStrategy; import mybatis.mate.strategy.SensitiveStrategy; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; @Configuration public class SensitiveStrategyConfig { /** * 注入脱敏策略 */ @Bean public ISensitiveStrategy sensitiveStrategy() { // 自定义 testStrategy 类型脱敏处理 return new SensitiveStrategy().addStrategy("testStrategy", t -> t + "***test***"); } }5、业务类User，注解标识脱敏字段，及选用脱敏策略package mybatis.mate.sensitive.jackson.entity; import lombok.Getter; import lombok.Setter; import mybatis.mate.annotation.FieldSensitive; import mybatis.mate.sensitive.jackson.config.SensitiveStrategyConfig; import mybatis.mate.strategy.SensitiveType; @Getter @Setter public class User { private Long id; /** * 这里是一个自定义的策略 {@link SensitiveStrategyConfig} 初始化注入 */ @FieldSensitive("testStrategy") private String username;
