1.什么是ip2region？

ip2region v2.0 - 是一个离线IP地址定位库和IP定位数据管理框架，10微秒级别的查询效率，提供了众多主流编程语言的 xdb 数据生成和查询客户端实现。

Ip2region 特性

1、标准化的数据格式

每个 ip 数据段的 region 信息都固定了格式：国家|区域|省份|城市|ISP，只有中国的数据绝大部分精确到了城市，其他国家部分数据只能定位到国家，后前的选项全部是0。

2、数据去重和压缩

xdb 格式生成程序会自动去重和压缩部分数据，默认的全部 IP 数据，生成的 ip2region.xdb 数据库是 11MiB，随着数据的详细度增加数据库的大小也慢慢增大。

3、极速查询响应

即使是完全基于 xdb 文件的查询，单次查询响应时间在十微秒级别，可通过如下两种方式开启内存加速查询：

• vIndex 索引缓存 ：使用固定的 512KiB 的内存空间缓存 vector index 数据，减少一次 IO 磁盘操作，保持平均查询效率稳定在10-20微秒之间。
• xdb 整个文件缓存：将整个 xdb 文件全部加载到内存，内存占用等同于 xdb 文件大小，无磁盘 IO 操作，保持微秒级别的查询效率。

4、IP 数据管理框架

v2.0 格式的 xdb 支持亿级别的 IP 数据段行数，region 信息也可以完全自定义，例如：你可以在 region 中追加特定业务需求的数据，例如：GPS信息/国际统一地域信息编码/邮编等。也就是你完全可以使用 ip2region 来管理你自己的 IP 定位数据。

2.代码工程

实验目标

根据来源ip 判断属于那个国家，然后做过滤

Util

离线查询ip来源，

下载离线IP定位库

离线数据库在项目的data文件夹下，名称为ip2region.db，其他2个文件是用于生成离线库的，可不用下载。

https://github.com/lionsoul2014/ip2region/tree/master/data/ip2region.xdb

以上只是一些关键代码，所有代码请参见下面代码仓库

代码仓库

• https://github.com/Harries/springboot-demo(ipfilter）

3.测试

• 启动 springBoot应用
• 访问http://127.0.0.1:8088/hello?ip=52.220.113.16
• 可以看到该ip属于新加坡，后续可以根据国家限制访问

以上就是SpringBoot集成ip2region实现ip白名单的代码示例的详细内容，更多关于SpringBoot ip白名单的资料请关注编程客栈(www.devze.com)其它相关文章！
