SpringBoot使用自定義注解實(shí)現(xiàn)數(shù)據(jù)脫敏過程詳細(xì)解析
更新時間：2023年02月15日 14:36:40 作者：碼農(nóng)-文若書生
這篇文章主要介紹了SpringBoot自定義注解之脫敏注解詳解，具有很好的參考價值，希望對大家有所幫助。如有錯誤或未考慮完全的地方，望不吝賜教
前言
對于某些接口返回的信息，涉及到敏感數(shù)據(jù)的必須進(jìn)行脫敏操作，例如銀行卡號、身份證號、手機(jī)號等，脫敏方式有多種方式?？梢孕薷腟QL語句，也可以寫硬代碼，也可以修改JSON序列化，這里介紹通過修改Jackson序列化方式實(shí)現(xiàn)數(shù)據(jù)脫敏。
一、引入hutool工具類
maven:
<dependency>
<groupId>cn.hutool</groupId>
<artifactId>hutool-all</artifactId>
<version>5.8.5</version>
</dependency>
gradle:
// https://mvnrepository.com/artifact/cn.hutool/hutool-all
implementation group: 'cn.hutool', name: 'hutool-all', version: '5.8.5'
二、定義常用需要脫敏的數(shù)據(jù)類型的枚舉
其中 OTHER類型為自定義類型，需在后面自定義脫敏的長度等。
package com.iscas.authentication.model.enums;
import lombok.Getter;
/**
*
* @version 1.0
* @since jdk1.8
*/
@Getter
public enum PrivacyTypeEnum {
/**
* 中文名
* */
CHINESE_NAME,
/**
* 固話
* */
FIXED_PHONE,
/**
* 手機(jī)號
* */
MOBILE_PHONE,
/**
* 住址
* */
ADDRESS,
/**
* 密碼
* */
PASSWORD,
/**
* 銀行卡號
* */
BANK_CARD,
/**
* 郵箱
* */
EMAIL,
/**
* 身份證
* */
ID_CARD,
/**
* 其他類型
* */
OTHER;
}
三、定義脫敏方式枚舉
其中，DEFAULT類型時，需要數(shù)據(jù)類型為上一步枚舉中除OTHER外的已確定的類型，NONE表示不做脫敏，其他類型為注釋的意思。
package com.iscas.authentication.model.enums;
/**
*
* @version 1.0
* @since jdk1.8
*/
public enum DesensitizationTypeEnum {
/**
* 默認(rèn)方式
* */
DEFAULT,
/**
* 頭部脫敏
* */
HEAD,
/**
* 尾部脫敏
* */
TAIL,
/**
* 中間脫敏
* */
MIDDLE,
/**
* 頭尾脫敏
* */
HEAD_TAIL,
/**
* 全部脫敏
* */
ALL,
/**
* 不脫敏，相當(dāng)于沒打這個注解
* */
NONE;
}
四、自定義脫敏的注解
其中，mode默認(rèn)為DEFAULT，此時只需要設(shè)置dataType的類型為除OTHER外的確定類型即可，當(dāng)mode不是DEFAULT或NONE時，根據(jù)不同的類型，headNoMaskLen等長度屬性需要設(shè)置，見上面的注釋的字面意思。
package com.iscas.authentication.annotation;
import com.fasterxml.jackson.annotation.JacksonAnnotationsInside;
import com.fasterxml.jackson.databind.annotation.JsonSerialize;
import com.iscas.authentication.model.enums.DesensitizationTypeEnum;
import com.iscas.authentication.model.enums.PrivacyTypeEnum;
import com.iscas.authentication.service.DesensitizationSerializer;
import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;
/**
* 脫敏注解
*
* @version 1.0
* @since jdk1.8
*/
@Target(ElementType.FIELD)
@Retention(RetentionPolicy.RUNTIME)
@JacksonAnnotationsInside
@JsonSerialize(using = DesensitizationSerializer.class)
public @interface Desensitization {
/**
* 脫敏的隱私數(shù)據(jù)類型
*/
PrivacyTypeEnum dataType();
/**
* 脫敏方式,默認(rèn)方式不需要定義下面脫敏長度等信息，根據(jù)脫敏的隱私數(shù)據(jù)類型自動脫敏
*/
DesensitizationTypeEnum mode() default DesensitizationTypeEnum.DEFAULT;
/**
* 尾部不脫敏的長度，當(dāng)mode為HEAD或MIDDLE時使用
*/
int tailNoMaskLen() default 1;
/**
* 頭部不脫敏的長度，當(dāng)mode為TAIL或MIDDLE時使用
*/
int headNoMaskLen() default 1;
/**
* 中間不脫敏的長度，當(dāng)mode為HEAD_TAIL時使用
*/
int middleNoMaskLen() default 1;
/**
* 打碼
*/
char maskCode() default '*';
}
五、自定義Jackson的序列化方式
package com.iscas.authentication.service;
import cn.hutool.core.util.DesensitizedUtil;
import cn.hutool.core.util.StrUtil;
import com.fasterxml.jackson.core.JsonGenerator;
import com.fasterxml.jackson.databind.BeanProperty;
import com.fasterxml.jackson.databind.JsonMappingException;
import com.fasterxml.jackson.databind.JsonSerializer;
import com.fasterxml.jackson.databind.SerializerProvider;
import com.fasterxml.jackson.databind.ser.ContextualSerializer;
import com.iscas.authentication.annotation.Desensitization;
import com.iscas.authentication.model.enums.DesensitizationTypeEnum;
import com.iscas.authentication.model.enums.PrivacyTypeEnum;
import lombok.AllArgsConstructor;
import lombok.NoArgsConstructor;
import java.io.IOException;
import java.util.Objects;
/**

*

}
@Override

if (beanProperty != null) {
if (Objects.equals(beanProperty.getType().getRawClass(), String.class)) {
Desensitization desensitization = beanProperty.getAnnotation(Desensitization.class);
if (desensitization == null) {
desensitization = beanProperty.getContextAnnotation(Desensitization.class);
}
if (desensitization != null) {
return new DesensitizationSerializer(desensitization);
}
}
return serializerProvider.findValueSerializer(beanProperty.getType(), beanProperty);
}
return serializerProvider.findNullValueSerializer(null);
}
