IP地址的精细化操作（将IP地址转为相对应的地址）
第一步：
导入maven依赖：
<dependency>
<groupId>org.lionsoul</groupId>
<artifactId>ip2region</artifactId>
<version>1.7.2</version>
</dependency>
第二步，下载ip2region.db并将其放在resours下
第三步
插入代码
ceshiIP.java
package test;
import java.io.IOException;
import java.net.InetAddress;
import test.ttt;
public class ceshiIP0 {
public static void main(String[] args) throws IOException {
//获取IP地址
ttt t = new ttt();
String [] p=t.arr();//调用ttt.下的arr方法
String [] q=new String[p.length];//将获取后的城市加入数组中
for (int i=0;i<p.length;i++){
String hostAddress = p[i];
String detail = data1.getCityInfo(hostAddress);
q[i]="IP地址:"+hostAddress+"地区:"+detail;
System.out.println(q[i]);
// System.out.println("IP地址:"+hostAddress+"地区:"+detail);
}
}
}
data1.java（处理ip地址转化为城市）
package test; 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.IOException; import java.lang.reflect.Method; import java.net.URL; public class data1 { /** * 根据IP地址获取城市 * @param ip * 如果放在服务器读取不了,两种方式 * 1.可以在服务器上创建文件,ip2region.db这个放在文件里面，然后开始读取 * 2.可以整个配置文件,在配置配置目录，然后读取配置文件 * @return */ public static String getCityInfo(String ip) throws IOException { URL url = data1.class.getClassLoader().getResource("ip2region.db"); File file; if (url != null) { file = new File(url.getFile()); } else { return null; } if (!file.exists()) { System.out.println("Error: Invalid ip2region.db file, filePath：" + file.getPath()); return null; } //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, file.getPath()); Method method; 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; default: return null; } DataBlock dataBlock; if (!Util.isIpAddress(ip)) { System.out.println("Error: Invalid ip address"); return null; } dataBlock = (DataBlock) method.invoke(searcher, ip); return dataBlock.getRegion(); } catch (Exception e) { e.printStackTrace(); } return null; } }
ttt.java(从文件中取IP地址)
