一、 复制data文件夹到自己的项目当中
可以进行加载到这个文件即可 博主放入在项目的根目录当中

带入maven依赖 因为这个编辑器的原因 复制依赖 显示不出来淦!!!! 图片自己打吧
org.lionsoulip2region1.7.2

二、最重要的一步 编译地理位置
找到自己的项目地址
执行打开cmd 执行这段代码
java -Dfile.encoding=utf-8 -jar dbMaker-1.2.2.jar -src ./data/ip.merge.txt -region ./data/global_region.csv
java -Dfile.encoding=utf-8 -jar dbMaker-1.2.2.jar -src ./data/ip.merge.txt -region ./data/global_region.csv


请跟着一步步来


代码开始 创建iputils
package top.yangbuyi.system.webapi;
import org.lionsoul.ip2region.DataBlock;
import org.lionsoul.ip2region.DbConfig;
import org.lionsoul.ip2region.DbSearcher;
import org.lionsoul.ip2region.Util;
import java.io.File;
import java.io.UnsupportedEncodingException;
import java.lang.reflect.Method;
import java.net.URLDecoder;

*/
public class iputils {
public static String getCityInfo(String ip) throws UnsupportedEncodingException {
//db
String dbPath = new File("SQL/data/ip2region.db").getPath();
dbPath = URLDecoder.decode(dbPath, "UTF-8");
File file = new File(dbPath);
if (file.exists() == false) {
System.out.println("Error: Invalid ip2region.db file");
}
//查询算法
int algorithm = DbSearcher.BTREE_ALGORITHM; //B-tree
//DbSearcher.BINARY_ALGORITHM //Binary
//DbSearcher.MEMORY_ALGORITYM //Memory
try {
DbConfig config = new DbConfig();
DbSearcher searcher = new DbSearcher(config, dbPath);
//define the method
Method method = null;
switch (algorithm) {
case DbSearcher.BTREE_ALGORITHM:
method = searcher.getClass().getMethod("btreeSearch", String.class);
break;
case DbSearcher.BINARY_ALGORITHM:
method = searcher.getClass().getMethod("binarySearch", String.class);
break;
case DbSearcher.MEMORY_ALGORITYM:
method = searcher.getClass().getMethod("memorySearch", String.class);
break;
}
DataBlock dataBlock = null;
if (Util.isIpAddress(ip) == false) {
System.out.println("Error: Invalid ip address");
}
dataBlock = (DataBlock) method.invoke(searcher, ip);
String decode = URLDecoder.decode(dataBlock.getRegion(), "UTF-8");
return decode;
} catch (Exception e) {
e.printStackTrace();
}
return null;
}
public static void main(String[] args) throws Exception {
System.err.println(iputils.getCityInfo("106.18.167.102"));
}
}
最后 测试代码

太累了吧!!!!
