用户敏感信息脱敏展示

定义手机号和证件号的 Jackson 自定义序列化器，并在对应需要脱敏的敏感字段上指定自定义序列化器。在进行指定的需要脱敏的字段（身份证号，手机号，银行卡号等）序列化的时候，该字段自动变成脱敏json对象。

1）身份证号序列化器

java">import cn.hutool.core.util.DesensitizedUtil;
import com.fasterxml.jackson.core.JsonGenerator;
import com.fasterxml.jackson.databind.JsonSerializer;
import com.fasterxml.jackson.databind.SerializerProvider;import java.io.IOException;/*** 身份证号脱敏反序列化*/
public class IdCardDesensitizationSerializer extends JsonSerializer<String> {@Overridepublic void serialize(String idCard, JsonGenerator jsonGenerator, SerializerProvider serializerProvider) throws IOException {String phoneDesensitization = DesensitizedUtil.idCardNum(idCard, 4, 4);jsonGenerator.writeString(phoneDesensitization);}
}

2）手机号序列化器

java">import cn.hutool.core.util.DesensitizedUtil;
import com.fasterxml.jackson.core.JsonGenerator;
import com.fasterxml.jackson.databind.JsonSerializer;
import com.fasterxml.jackson.databind.SerializerProvider;import java.io.IOException;/*** 手机号脱敏反序列化*/
public class PhoneDesensitizationSerializer extends JsonSerializer<String> {@Overridepublic void serialize(String phone, JsonGenerator jsonGenerator, SerializerProvider serializerProvider) throws IOException {String phoneDesensitization = DesensitizedUtil.mobilePhone(phone);jsonGenerator.writeString(phoneDesensitization);}
}

3） 敏感字段上自定义序列化器。

java">import com.fasterxml.jackson.annotation.JsonFormat;
import com.fasterxml.jackson.databind.annotation.JsonSerialize;
import lombok.experimental.Accessors;import java.util.Date;/*** 乘车人返回参数*/
@Data
@Accessors(chain = true)
public class PassengerRespDTO {/*** 证件号码*/@JsonSerialize(using = IdCardDesensitizationSerializer.class)private String idCard;/*** 手机号*/@JsonSerialize(using = PhoneDesensitizationSerializer.class)private String phone;
}
