方式一: 根据AOP切面进行数据的加密,经过层层的递归进行查找数据

方式二:自定义反序列化器

package com.haenu.shortlink.common.serialize;

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> {

    @Override
    public void serialize(String idCard, JsonGenerator jsonGenerator, SerializerProvider serializerProvider) throws IOException {
        String phoneDesensitization = DesensitizedUtil.idCardNum(idCard, 4, 4);
        jsonGenerator.writeString(phoneDesensitization);
    }
}

package com.haenu.shortlink.common.serialize;

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> {

    @Override
    public void serialize(String phone, JsonGenerator jsonGenerator, SerializerProvider serializerProvider) throws IOException {
        String phoneDesensitization = DesensitizedUtil.mobilePhone(phone);
        jsonGenerator.writeString(phoneDesensitization);
    }
}

如何去启用?

只需要在DTO字段上加

@JsonSerialize(using = PhoneDesensitizationSerializer.class)

/**
     * 手机号
     */
    @JsonSerialize(using = PhoneDesensitizationSerializer.class)
    private String phone;
