数据脱敏常用在电话号码和身份证号，本文主要介绍了Java数据脱敏常用方法，文中通过示例代码介绍的非常详细，对大家的学习或者工作具有一定的参考学习价值，需要的朋友们下面随着小编来一起学习学习吧

1.SQL数据脱敏实现

-- 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_user

2.JAVA数据脱敏实现

可参考：海强 / sensitive-plus

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。

mybatis-mate-sensitive-jackson

mybatisplus 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";
}

            <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

# Logger Config
logging:
  level:
    mybatis.mate: debug

3、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;
    /**
     * 默认支持策略 {@link SensitiveType }
     */
    @FieldSensitive(SensitiveType.mobile)
    private String mobile;
    @FieldSensitive(SensitiveType.email)
    private String email;
}

UserController

package mybatis.mate.sensitive.jackson.controller;
import mybatis.mate.databind.ISensitiveStrategy;
import mybatis.mate.databind.RequestDataTransfer;
import mybatis.mate.sensitive.jackson.entity.User;
import mybatis.mate.sensitive.jackson.mapper.UserMapper;
import mybatis.mate.strategy.SensitiveType;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
import javax.servlet.http.HttpServletRequest;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
@RestController
public class UserController {
    @Autowired
    private UserMapper userMapper;
    @Autowired
    private ISensitiveStrategy sensitiveStrategy;
    // 测试访问 http://localhost:8080/info
    @GetMapping("/info")
    public User info() {
        return userMapper.selectById(1L);
    }
    // 测试返回 map 访问 http://localhost:8080/map
    @GetMapping("/map")
    public Map<String, Object> map() {
        // 测试嵌套对象脱敏
        Map<String, Object> userMap = new HashMap<>();
        userMap.put("user", userMapper.selectById(1L));
        userMap.put("test", 123);
        userMap.put("userMap", new HashMap<String, Object>() {{
            put("user2", userMapper.selectById(2L));
            put("test2", "hi china");
        }});
        // 手动调用策略脱敏
        userMap.put("mobile", sensitiveStrategy.getStrategyFunctionMap()
                .get(SensitiveType.mobile).apply("15315388888"));
        return userMap;
    }
    // 测试访问 http://localhost:8080/list
    // 不脱敏 http://localhost:8080/list?skip=1
    @GetMapping("/list")
    public List<User> list(HttpServletRequest request) {
        if ("1".equals(request.getParameter("skip"))) {
            // 跳过脱密处理
            RequestDataTransfer.skipSensitive();
        }
        return userMapper.selectList(null);
    }
}

UserMapper

package mybatis.mate.sensitive.jackson.mapper;
import com.baomidou.mybatisplus.core.mapper.BaseMapper;
import mybatis.mate.sensitive.jackson.entity.User;
import org.apache.ibatis.annotations.Mapper;
@Mapper
public interface UserMapper extends BaseMapper<User> {
}

6、测试

GET http://localhost:8080/list

[
  {
    "id": 1,
    "username": "Jone***test***",
    "mobile": "153******81",
    "email": "t****@baomidou.com"
  },
  {
    "id": 2,
    "username": "Jack***test***",
    "mobile": "153******82",
    "email": "t****@baomidou.com"
  },
  {
    "id": 3,
    "username": "Tom***test***",
    "mobile": "153******83",
    "email": "t****@baomidou.com"
  }
]

GET http://localhost:8080/list?skip&#61;1

[
  {
    "id": 1,
    "username": "Jone",
    "mobile": "15315388881",
    "email": "test1@baomidou.com"
  },
  {
    "id": 2,
    "username": "Jack",
    "mobile": "15315388882",
    "email": "test2@baomidou.com"
  },
  {
    "id": 3,
    "username": "Tom",
    "mobile": "15315388883",
    "email": "test3@baomidou.com"
  }
]
