springboot 利用fastjson脱敏数据库数据(自定义注解)
作者:互联网
1. 自定义脱敏注解
package com.hanhuide.hhde.annotation;
import com.hanhuide.hhde.enums.SensitiveTypeEnum;
import java.lang.annotation.*;
@Target({ElementType.FIELD, ElementType.METHOD})
@Retention(RetentionPolicy.RUNTIME)
@Inherited
@Documented
public @interface Desensitized {
// 脱敏类型(规则)
SensitiveTypeEnum type();
}
2.定义脱敏类型
package com.hanhuide.hhde.enums;
public enum SensitiveTypeEnum {
/**
* 中文名
*/
CHINESE_NAME,
/**
* 身份证号
*/
ID_CARD,
/**
* 座机号
*/
FIXED_PHONE,
/**
* 手机号
*/
MOBILE_PHONE,
/**
* 地址
*/
ADDRESS,
/**
* 电子邮件
*/
EMAIL,
/**
* 银行卡
*/
BANK_CARD,
/**
* 密码
*/
PASSWORD,
/**
* 车牌号
*/
CARNUMBER;
}
3. 编辑脱敏工具类
package com.hanhuide.hhde.utils;
import com.alibaba.fastjson.JSON;
import com.alibaba.fastjson.serializer.SerializerFeature;
import com.hanhuide.hhde.annotation.Desensitized;
import org.apache.commons.lang3.StringUtils;
import java.lang.reflect.*;
import java.util.*;
/**
* @Title: DesensitizedUtils
*/
public class DesensitizedUtils {
/**
* 【中文姓名】只显示第一个汉字,其他隐藏为2个星号,比如:李**
*
* @param fullName
* @return
*/
public static String chineseName(String fullName) {
if (StringUtils.isBlank(fullName)) {
return "";
}
String name = StringUtils.left(fullName, 1);
return StringUtils.rightPad(name, StringUtils.length(fullName), "*");
}
/**
* 【身份证号】显示最后四位,其他隐藏。共计18位或者15位,比如:*************1234
*
* @param id
* @return
*/
public static String idCardNum(String id) {
if (StringUtils.isBlank(id)) {
return "";
}
String num = StringUtils.right(id, 4);
return StringUtils.leftPad(num, StringUtils.length(id), "*");
}
/**
* 【固定电话 后四位,其他隐藏,比如1234
*
* @param num
* @return
*/
public static String fixedPhone(String num) {
if (StringUtils.isBlank(num)) {
return "";
}
return StringUtils.leftPad(StringUtils.right(num, 4), StringUtils.length(num), "*");
}
/**
* 【手机号码】前三位,后四位,其他隐藏,比如135******10
*
* @param num
* @return
*/
public static String mobilePhone(String num) {
if (StringUtils.isBlank(num)) {
return "";
}
return StringUtils.left(num, 3).concat(StringUtils.removeStart(StringUtils.leftPad(StringUtils.right(num, 2), StringUtils.length(num), "*"), "***"));
}
/**
* 【地址】只显示到地区,不显示详细地址,比如:北京市海淀区****
*
* @param address
* @param sensitiveSize 敏感信息长度
* @return
*/
public static String address(String address, int sensitiveSize) {
if (StringUtils.isBlank(address)) {
return "";
}
int length = StringUtils.length(address);
return StringUtils.rightPad(StringUtils.left(address, length - sensitiveSize), length, "*");
}
/**
* 【电子邮箱 邮箱前缀仅显示第一个字母,前缀其他隐藏,用星号代替,@及后面的地址显示,比如:d**@126.com>
*
* @param email
* @return
*/
public static String email(String email) {
if (StringUtils.isBlank(email)) {
return "";
}
int index = StringUtils.indexOf(email, "@");
if (index <= 1) {
return email;
} else {
return StringUtils.rightPad(StringUtils.left(email, 1), index, "*").concat(StringUtils.mid(email, index, StringUtils.length(email)));
}
}
/**
* 【银行卡号】前六位,后四位,其他用星号隐藏每位1个星号,比如:6222600**********1234>
*
* @param cardNum
* @return
*/
public static String bankCard(String cardNum) {
if (StringUtils.isBlank(cardNum)) {
return "";
}
return StringUtils.left(cardNum, 6).concat(StringUtils.removeStart(StringUtils.leftPad(StringUtils.right(cardNum, 4), StringUtils.length(cardNum), "*"), "******"));
}
/**
* 【密码】密码的全部字符都用*代替,比如:******
*
* @param password
* @return
*/
public static String password(String password) {
if (StringUtils.isBlank(password)) {
return "";
}
String pwd = StringUtils.left(password, 0);
return StringUtils.rightPad(pwd, StringUtils.length(password), "*");
}
/**
* 【车牌号】前两位后一位,比如:苏M****5
*
* @param carNumber
* @return
*/
public static String carNumber(String carNumber) {
if (StringUtils.isBlank(carNumber)) {
return "";
}
return StringUtils.left(carNumber, 2).
concat(StringUtils.removeStart(StringUtils.leftPad(StringUtils.right(carNumber, 1), StringUtils.length(carNumber), "*"), "**"));
}
}
4. 实现ValueFilter 接口 在process添加自己的处理步骤
package com.hanhuide.hhde.filter;
import com.alibaba.fastjson.serializer.ValueFilter;
import java.lang.reflect.Field;
import com.hanhuide.hhde.annotation.Desensitized;
import com.hanhuide.hhde.enums.SensitiveTypeEnum;
import com.hanhuide.hhde.utils.DesensitizedUtils;
import lombok.extern.slf4j.Slf4j;
/**
* 在fastjson中使用此过滤器进行脱敏操作
*/
@Slf4j
public class ValueDesensitizeFilter implements ValueFilter {
@Override
public Object process(Object object, String name, Object value) {
if (null == value || !(value instanceof String) || ((String) value).length() == 0) {
return value;
}
try {
Field field = object.getClass().getDeclaredField(name);
Desensitized desensitization;
if (String.class != field.getType() || (desensitization = field.getAnnotation(Desensitized.class)) == null) {
return value;
}
String valueStr = (String) value;
SensitiveTypeEnum type = desensitization.type();
switch (type) {
case CHINESE_NAME:
return DesensitizedUtils.chineseName(valueStr);
case ID_CARD:
return DesensitizedUtils.idCardNum(valueStr);
case FIXED_PHONE:
return DesensitizedUtils.fixedPhone(valueStr);
case MOBILE_PHONE:
return DesensitizedUtils.mobilePhone(valueStr);
case ADDRESS:
return DesensitizedUtils.address(valueStr, 8);
case EMAIL:
return DesensitizedUtils.email(valueStr);
case BANK_CARD:
return DesensitizedUtils.bankCard(valueStr);
case PASSWORD:
return DesensitizedUtils.password(valueStr);
case CARNUMBER:
return DesensitizedUtils.carNumber(valueStr);
default:
}
} catch (NoSuchFieldException e) {
log.error("当前数据类型为{},值为{}", object.getClass(), value);
return value;
}
return value;
}
}
5. 配置fastjson为默认JSON转换
package com.hanhuide.hhde.config;
import com.alibaba.fastjson.serializer.SerializerFeature;
import com.alibaba.fastjson.support.config.FastJsonConfig;
import com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter;
import com.hanhuide.hhde.factory.DesensitizedAnnotationFormatterFactory;
import com.hanhuide.hhde.filter.ValueDesensitizeFilter;
import lombok.extern.slf4j.Slf4j;
import org.springframework.boot.autoconfigure.http.HttpMessageConverters;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.format.FormatterRegistry;
import org.springframework.http.MediaType;
import org.springframework.http.converter.HttpMessageConverter;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
import java.util.ArrayList;
import java.util.List;
@Configuration
@Slf4j
public class WebConfigurer implements WebMvcConfigurer {
@Override
public void addFormatters(FormatterRegistry registry) {
log.info("启用自定义注解!!!");
registry.addFormatterForFieldAnnotation(new DesensitizedAnnotationFormatterFactory());
}
/**
* 配置fastjson为默认JSON转换
*
* @return
*/
@Bean
public HttpMessageConverters fastJsonHttpMessageConverters() {
// 1.定义一个converters转换消息的对象
FastJsonHttpMessageConverter fastConverter = new FastJsonHttpMessageConverter();
// 2.添加fastjson的配置信息,比如: 是否需要格式化返回的json数据
FastJsonConfig fastJsonConfig = new FastJsonConfig();
fastJsonConfig.setSerializerFeatures(SerializerFeature.PrettyFormat);
fastJsonConfig.setSerializeFilters(new ValueDesensitizeFilter());//添加自己写的拦截器
// 3.在converter中添加配置信息
fastConverter.setFastJsonConfig(fastJsonConfig);
// 4.将converter赋值给HttpMessageConverter
HttpMessageConverter<?> converter = fastConverter;
// 5.返回HttpMessageConverters对象
return new HttpMessageConverters(converter);
