类 IpRegionUtils

java.lang.Object

org.apache.shenyu.plugin.sign.utils.IpRegionUtils

public final class IpRegionUtils
extends java.lang.Object

Utility for offline IP geolocation lookup using ip2region xdb.

Ported from api-gateway: com.tydic.newretail.util.IPUtils.ip2region(). Adapted for WebFlux: the entire xdb (11 MB) is loaded into memory once at class-loading time via Searcher.newWithBuffer(byte[]), so subsequent searchRegion(String) calls are purely in-memory and safe to call on Netty event-loop threads (no blocking file I/O).

Region result format (same as api-gateway): "国家|区域|省份|城市|ISP" e.g. "中国|0|北京市|北京市|电信"
