java如何查询本机ip地址和mac地址

   Java中可以使用程序来获取本地ip地址和mac地址,使用InetAddress这个工具类,示例如下:

import java.net.*;

public class NetInfo {

 public static void main(String[] args) {

    new NetInfo().say();

    }

 public void say() {

   try {

   InetAddress i = InetAddress.getLocalHost();

   System.out.println(i);                  //计算机名称和IP

   System.out.println(i.getHostName());    //名称

   System.out.println(i.getHostAddress()); //只获得IP

   }

   catch(Exception e){e.printStackTrace();}

 }

}

    也可以通过命令行窗口来查看本地ip和mac地址,输入命令:ipconfig。

java 如何计算一个ip的归属地

import java.io.BufferedReader;

import java.io.InputStreamReader;

import java.net.URL;

import java.net.URLConnection;

public class Test {

public static void main(String[] args) throws Exception {

//查询IP的接口;ip=123.115.132.140appkey=10003sign=b59bc3ef6191eb9f747dd4e83c99f2a4format=json

BufferedReader br = new BufferedReader(new InputStreamReader(System.in));

System.out.println("请输入要查询的IP地址:");

String ip = br.readLine();

String str_url = ";ip="+ip+"appkey=10003sign=b59bc3ef6191eb9f747dd4e83c99f2a4format=json";

URL url = new URL(str_url);

URLConnection conn = url.openConnection();

BufferedReader retun = new BufferedReader(new InputStreamReader(conn.getInputStream()));

//这里返回的是一个JSON的格式,自己解析吧。

System.out.println(retun.readLine());

retun.close();

}

}

如何用java获取本地ip地址

import java.net.Inet4Address;

import java.net.InetAddress;

import java.net.NetworkInterface;

import java.net.SocketException;

import java.util.ArrayList;

import java.util.Enumeration;

import java.util.List;

/**

*/

public class IpAddress {

public static String find() {

ListString ips = new ArrayListString();

// 返回所有网络接口的一个枚举实例

Enumeration? allNetInterfaces = null;

try {

allNetInterfaces = NetworkInterface.getNetworkInterfaces();

} catch (SocketException e) {

e.printStackTrace();

}

InetAddress ip = null;

while (allNetInterfaces.hasMoreElements()) {

NetworkInterface netInterface = (NetworkInterface) allNetInterfaces.nextElement();

EnumerationInetAddress addresses = netInterface.getInetAddresses();

while (addresses.hasMoreElements()) {

// 获得当前网络接口

ip = (InetAddress) addresses.nextElement();

if (ip != null ip instanceof Inet4Address ip.getHostAddress().indexOf(".") != -1) {

ips.add(ip.getHostAddress());

}

}

}

if (ips.size() == 1) {

return ips.get(0);

} else {

for (String ipa : ips) {

if (!"127.0.0.1".equals(ipa)) {

return ipa;

}

}

}

return MacAddress.find();

}

}

java IP查询方法

Java编程查询IP地址归属地,可以调用淘宝提供的service查询,并且解析http请求返回的json串,代码如下:

package getAddressByIp;

import java.io.ByteArrayOutputStream;

import java.io.IOException;

import java.io.InputStream;

import java.net.HttpURLConnection;

import java.net.MalformedURLException;

import java.net.URL;

import net.sf.json.JSONObject;

 

public class GetAddressByIp

{        

    /**

     * 

     * @param IP

     * @return

     */

    public static String GetAddressByIp(String IP){

        String resout = "";

        try{

         String str = getJsonContent(""+IP);

         System.out.println(str);

         JSONObject obj = JSONObject.fromObject(str);

         JSONObject obj2 =  (JSONObject) obj.get("data");

         String code = (String) obj.get("code");

         if(code.equals("0")){

             resout =  obj2.get("country")+"--" +obj2.get("area")+"--" +obj2.get("city")+"--" +obj2.get("isp");

         }else{

             resout =  "IP地址有误";

         }

        }catch(Exception e){

             

            e.printStackTrace();

             resout = "获取IP地址异常:"+e.getMessage();

        }

        return resout;

          

    }

    

    public static String getJsonContent(String urlStr)

    {

        try

        {// 获取HttpURLConnection连接对象

            URL url = new URL(urlStr);

            HttpURLConnection httpConn = (HttpURLConnection) url.openConnection();

            // 设置连接属性

            httpConn.setConnectTimeout(3000);

            httpConn.setDoInput(true);

            httpConn.setRequestMethod("GET");

            // 获取相应码

            int respCode = httpConn.getResponseCode();

            if (respCode == 200)

            {

                return ConvertStream2Json(httpConn.getInputStream());

            }

        }

        catch (MalformedURLException e)

        {

            e.printStackTrace();

        }

        catch (IOException e)

        {

            e.printStackTrace();

        }

        return "";

    }

    

    private static String ConvertStream2Json(InputStream inputStream)

    {

        String jsonStr = "";

        // ByteArrayOutputStream相当于内存输出流

        ByteArrayOutputStream out = new ByteArrayOutputStream();

        byte[] buffer = new byte[1024];

        int len = 0;

        // 将输入流转移到内存输出流中

        try

        {

            while ((len = inputStream.read(buffer, 0, buffer.length)) != -1)

            {

                out.write(buffer, 0, len);

            }

            // 将内存流转换为字符串

            jsonStr = new String(out.toByteArray());

        }

        catch (IOException e)

        {

            // TODO Auto-generated catch block

            e.printStackTrace();

        }

        return jsonStr;

    }

}

java中获取本地IP地址

方法如下:

方法一,使用CMD命令:

public static String getLocalIPForCMD(){

StringBuilder sb = new StringBuilder();

String command = "cmd.exe /c ipconfig | findstr IPv4";

try {

Process p = Runtime.getRuntime().exec(command);

BufferedReader br = new BufferedReader(new InputStreamReader(p.getInputStream()));

String line = null;

while((line = br.readLine()) != null){

line = line.substring(line.lastIndexOf(":")+2,line.length());

sb.append(line);

}

br.close();

p.destroy();

} catch (IOException e) {

e.printStackTrace();

}

return sb.toString();

}

方法二,使用Java方法:

public static String getLocalIPForJava(){

StringBuilder sb = new StringBuilder();

try {

EnumerationNetworkInterface en = NetworkInterface.getNetworkInterfaces();

while (en.hasMoreElements()) {

NetworkInterface intf = (NetworkInterface) en.nextElement();

EnumerationInetAddress enumIpAddr = intf.getInetAddresses();

while (enumIpAddr.hasMoreElements()) {

InetAddress inetAddress = (InetAddress) enumIpAddr.nextElement();

if (!inetAddress.isLoopbackAddress() !inetAddress.isLinkLocalAddress()

inetAddress.isSiteLocalAddress()) {

sb.append(inetAddress.getHostAddress().toString()+"\n");

}

}

}

} catch (SocketException e) { }

return sb.toString();

}
