说明:
公司之前数据接口数据管理不严格,很多接口的敏感数据都没有脱敏处理,直接返回给前端了,然后被甲方的第三方安全漏洞扫出来,老板要求紧急处理,常用的话在单个字段上加上脱敏注解会更加的灵活,但是时间有点紧,一个个返回对象的响应参数里面的单个字段处理比较耗时间
想法:
就是快!!!快速处理
利用aop注解,对返回的对象进行处理,默认一些常用的需要脱敏的字段名,比如password、mobile、idCardNo等,支持自定义对象名称列表。同时如果返回的是个列表,则需要对列表里面的值也都遍历处理。
直接在controller接口上添加注解,就能对返回的数据做全局处理,不要一个个对象里面的一个个字段进行处理。
效果
实操:
1、pom引入依赖
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-aop</artifactId>
</dependency>
<!-- hutool工具类 -->
<dependency>
<groupId>cn.hutool</groupId>
<artifactId>hutool-all</artifactId>
<version>5.8.15</version>
</dependency>
2、自定义注解
import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;
@Target(ElementType.METHOD)
@Retention(RetentionPolicy.RUNTIME)
public @interface SensitiveResponse {
/**
* 默认需要脱敏的字段列表
* @return 字段列表
*/
String[] value() default {"password", "mobile", "phone", "idCardNo", "email", "bankCardNo", "address"};
/**
* 默认字段上再增加的字段
* @return 字段列表
*/
String[] addValue() default {};
}

// 递归处理子对象字段脱敏
