所谓数据脱敏是指对某些敏感信息通过脱敏规则进行数据的变形，实现敏感隐私数据的可靠保护。在涉及客户安全数据或者一些商业性敏感数据的情况下，在不违反系统规则条件下，对真实数据进行改造并提供测试使用，如身份证号、手机号、卡号、客户号等个人信息都需要进行数据脱敏。
此随笔是根据其他文章修改后符合自己项目使用的数据脱敏！！
以下是根据别的文章修改或者直接拿过来用的代码脱敏enum
/** * @Title: SensitiveTypeEnum * @Description: */ 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; }
自定义annotation
/** * @Title: Desensitized * @Description: 敏感信息注解标记 */ @Target({ElementType.FIELD, ElementType.METHOD}) @Retention(RetentionPolicy.RUNTIME) @Inherited @Documented public @interface Desensitized { /*脱敏类型(规则)*/ SensitiveTypeEnum type(); /*判断注解是否生效的方法*/ String isEffictiveMethod() default ""; }

最后面的几个方法是我根据泛型和反射创建的对page、list 、实体的脱敏方法。
以下是我的代码
后端实体

返回结果给前端的VO

上面的身份证我添加了自定义的注解，在脱敏的时候会找到这个注解然后获取属性的值进行脱敏

}
}
JsonResponseExt je = JsonResponseExt.successPage()这个方法是自己封装给前端的返回对象（这里不提供）
根据工具类的 DesensitizedUtils.desensitizedPage()方法 传入page对象、page、limit和传回前端的VO的Class对象就可以进行脱敏了
