2、导入maven依赖
<dependency> <groupId>org.lionsoul</groupId> <artifactId>ip2region</artifactId> <version>1.7.2</version> </dependency>3、自定义工具类
package test import org.lionsoul.ip2region.{DbConfig, DbSearcher} object iputil { def main(args: Array[String]): Unit = { val dbFile = "E:\\test\\final_proj\\src\\main\\resources\\ip2region.db" val ip = "110.85.18.234" val search = new DbSearcher(new DbConfig(),dbFile) val datablock = search.btreeSearch(ip) println(datablock) //城市Id|国家|区域|省份|城市|ISP_ val db = datablock.getRegion println(db) val rep = db.replace("|",",") val spl = rep.split(",") val country = spl(0) val province = spl(2) val city = spl(3) println(country) println(province) println(city) } }
