数据脱敏
基于SpringBoot 实现数据脱敏
0、本文参考的链接
1、实现方法
1、最简单的的，项目中引入Hutool工具包，调用其中的方法即可。【个人觉得不太好】
2、本文采用jackson去实现，jackson的简单学习 可以参考jackson
2、项目依赖：SpringBoot-Web 、Apache.common、lombok
PS: Spring默认的序列化框架就是 jackson，所以不需要单独引入

<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>org.apache.commons</groupId>
<artifactId>commons-lang3</artifactId>
<version>3.12.0</version>
</dependency>
<dependency>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
<optional>true</optional>
</dependency>
3、定义脱敏枚举类
点击查看代码
/**
* 数据脱敏类型
*/
public enum SensitiveEnum {
/**
* 身份证号码
*/
ID_CARD,
/**
* 电子邮件
*/
EMAIL,
/**
* 手机号码
*/
MOBILE_PHONE;
}
4、不同类型字段脱敏处理
点击查看代码
public class SensitiveUtils {
/**
* 身份证脱敏
*
* @param idcard
* @return
*/
public static String isCardNumber(String idcard) {
if (StringUtils.isBlank(idcard)) {
return "";
}
return StringUtils.left(idcard, 3).concat(StringUtils
.removeStart(StringUtils.leftPad(StringUtils.right(idcard, 4), StringUtils.length(idcard), "*"),
"***"));
}
/**
* 电子邮箱脱敏
*
* @param email
* @return
*/
public static String email(String email) {
if (StringUtils.isBlank(email)) {
return "";
}
if (StringUtils.indexOf(email, "@") <= 1) {
return "";
}
return StringUtils.leftPad(
StringUtils.right(email, StringUtils.length(email) - StringUtils.indexOf(email, "@")),
StringUtils.length(email),
"*");
}
/**
* 手机号码
*
* @param phone
* @return
*/
public static String mobilePhone(String phone) {
if (StringUtils.isBlank(phone)) {
return "";
}
return StringUtils.left(phone, 3).concat(StringUtils
.removeStart(StringUtils.leftPad(StringUtils.right(phone, 4), StringUtils.length(phone), "*"),
"***"));
}
}
5、实现序列化类
点击查看代码
public class SensitiveSerialize extends JsonSerializer<String> implements ContextualSerializer {
SensitiveEnum enumtype;
public SensitiveSerialize() {
}
public SensitiveSerialize(SensitiveEnum type) {
this.enumtype = type;
}
@Override
public void serialize(String s, JsonGenerator jsonGenerator, SerializerProvider serializerProvider) throws IOException {
switch (this.enumtype) {
case ID_CARD:
jsonGenerator.writeString(SensitiveUtils.isCardNumber(s));
break;
case EMAIL:
jsonGenerator.writeString(SensitiveUtils.email(s));
break;
case MOBILE_PHONE:
jsonGenerator.writeString(SensitiveUtils.mobilePhone(s));
break;
}
}
@Override
public JsonSerializer<?> createContextual(SerializerProvider serializerProvider, BeanProperty beanProperty) throws JsonMappingException {
if (!Objects.isNull(beanProperty)) {
if (Objects.equals(beanProperty.getType().getRawClass(), String.class)) {
SensitiveAnnantion sensitiveAnnantion = beanProperty.getAnnotation(SensitiveAnnantion.class);
if (Objects.isNull(sensitiveAnnantion)) {
sensitiveAnnantion = beanProperty.getContextAnnotation(SensitiveAnnantion.class);
} else {
return new SensitiveSerialize(sensitiveAnnantion.value());
}
}
return serializerProvider.findValueSerializer(beanProperty.getType(), beanProperty);
}
return serializerProvider.findNullValueSerializer(beanProperty);
}
}
6、定义注解
点击查看代码
@Retention(RetentionPolicy.RUNTIME)
@JacksonAnnotationsInside
@JsonSerialize(using = SensitiveSerialize.class)
public @interface SensitiveAnnantion {
SensitiveEnum value();
}
7、测试
点击查看代码
## 实体类
@Data
@AllArgsConstructor
@Builder
public class UserModel {
private Long userid;
private String username;
@SensitiveAnnantion(value = SensitiveEnum.EMAIL)
private String email;
@SensitiveAnnantion(value = SensitiveEnum.MOBILE_PHONE)
private String phone;
@SensitiveAnnantion(value = SensitiveEnum.ID_CARD)
private String idcard;
}
## controller
@RestController
public class DemoController {
@GetMapping(value = "/query")
public UserModel Query() {
return UserModel.builder()
.email("2575102291@qq.com")
.phone("17609329556")
.idcard("111111111111111111")
.userid(2023L)
.username("张三")
.build();
}
}
## 测试结果
{
"userid": 2023,
"email": "**********@qq.com",
"username": "张三",
"phone": "176****9556",
"idcard": "111***********1111"
}
