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
下载到离线数据库后,我们需要读取这个数据库,我们可以放在项目的resources

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
