获取macjava

❶ 如何使用java代码获取Android移动终端Mac地址

通过设备开通WiFi连接获取Mac地址是最可取的，代码如下：

/**
* 设备开通WiFi连接，通过wifiManager获取Mac地址
*/
public static String getMacFromWifi(Context context){
ConnectivityManager connectivityManager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
State wifiState = connectivityManager.getNetworkInfo(ConnectivityManager.TYPE_WIFI).getState();
if(wifiState == NetworkInfo.State.CONNECTED){//判断当前是否使用wifi连接
WifiManager wifiManager = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);
if (!wifiManager.isWifiEnabled()) { //如果当前wifi不可用
wifiManager.setWifiEnabled(true);
}
WifiInfo wifiInfo = wifiManager.getConnectionInfo();
return wifiInfo.getMacAddress();
}
return null;
}

❷ 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：

importjava.net.*;
publicclassNetInfo{
publicstaticvoidmain(String[]args){
newNetInfo().say();
}
publicvoidsay(){
try{
InetAddressi=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(Exceptione){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。

❸ java中怎么获取电脑的mac地址

importjava.net.InetAddress;

importjava.net.NetworkInterface;

importjava.net.SocketException;

importjava.net.UnknownHostException;


/*

*物理地址是48位，别和ipv6搞错了

*/

publicclassLOCALMAC{


	/**

	*@paramargs

	*@throwsUnknownHostException

	*@throwsSocketException

	*/

	publicstaticvoidmain(String[]args)throwsUnknownHostException,SocketException{

		//TODOAuto-generatedmethodstub

		

		//得到IP，输出PC-201309011313/122.206.73.83

		InetAddressia=InetAddress.getLocalHost();

		System.out.println(ia);

		getLocalMac(ia);

	}


	privatestaticvoidgetLocalMac(InetAddressia)throwsSocketException{

		//TODOAuto-generatedmethodstub

		//获取网卡，获取地址

		byte[]mac=NetworkInterface.getByInetAddress(ia).getHardwareAddress();

		System.out.println("mac数组长度："+mac.length);

		StringBuffersb=newStringBuffer("");

		for(inti=0;i<mac.length;i++){

			if(i!=0){

				sb.append("-");

			}

			//字节转换为整数

			inttemp=mac[i]&0xff;

			Stringstr=Integer.toHexString(temp);

			System.out.println("每8位:"+str);

			if(str.length()==1){

				sb.append("0"+str);

			}else{

				sb.append(str);

			}

		}

		System.out.println("本机MAC地址:"+sb.toString().toUpperCase());

	}

}

❹ Java代码如何获取客户端的MAC地址

public String getMAC() { String mac = null; try { Process pro = Runtime.getRuntime().exec("cmd.exe /c ipconfig/all"); InputStream is = pro.getInputStream(); BufferedReader br = new BufferedReader(new InputStreamReader(is)); String message = br.readLine(); int index = -1; while (message != null) { if ((index = message.indexOf("Physical Address")) > 0) { mac = message.substring(index + 36).trim(); break; } message = br.readLine(); } System.out.println(mac); br.close(); pro.destroy(); } catch (IOException e) { System.out.println("Can't get mac address!"); return null; } return mac; }

❺ java 获取无线 mac地址吗

import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.LineNumberReader;

public class GetMac {

/**
* java获取客户端网卡的MAC地址
*
* @param args
*/
public static void main(String[] args) {
GetMac get = new GetMac();
System.out.println("1="+get.getMAC());
System.out.println("2="+get.getMAC("127.0.0.1"));
}

// 1.获取客户端ip地址( 这个必须从客户端传到后台)：
// jsp页面下，很简单，request.getRemoteAddr() ;
// 因为系统的VIew层是用JSF来实现的，因此页面上没法直接获得类似request，在bean里做了个强制转换

// public String getMyIP() {
// try {
// FacesContext fc = FacesContext.getCurrentInstance();
// HttpServletRequest request = (HttpServletRequest) fc
// .getExternalContext().getRequest();
// return request.getRemoteAddr();
// } catch (Exception e) {
// e.printStackTrace();
// }
// return "";
// }

// 2.获取客户端mac地址
// 调用window的命令，在后台Bean里实现 通过ip来获取mac地址。方法如下：

// 运行速度【快】
public String getMAC() {
String mac = null;
try {
Process pro = Runtime.getRuntime().exec("cmd.exe /c ipconfig/all");

InputStream is = pro.getInputStream();
BufferedReader br = new BufferedReader(new InputStreamReader(is));
String message = br.readLine();

int index = -1;
while (message != null) {
if ((index = message.indexOf("Physical Address")) > 0) {
mac = message.substring(index + 36).trim();
break;
}
message = br.readLine();
}
System.out.println(mac);
br.close();
pro.destroy();
} catch (IOException e) {
System.out.println("Can't get mac address!");
return null;
}
return mac;
}

// 运行速度【慢】
public String getMAC(String ip) {
String str = null;
String macAddress = null;
try {
Process p = Runtime.getRuntime().exec("nbtstat -A " + ip);
InputStreamReader ir = new InputStreamReader(p.getInputStream());
LineNumberReader input = new LineNumberReader(ir);
for (; true;) {
str = input.readLine();
if (str != null) {
if (str.indexOf("MAC Address") > 1) {
macAddress = str
.substring(str.indexOf("MAC Address") + 14);
break;
}
}
}
} catch (IOException e) {
e.printStackTrace(System.out);
return null;
}
return macAddress;
}
}

❻ JAVA如何获取客户端IP地址和MAC地址

/**
* 获取IP地址
* @return
*/
public static String GetNetIp() {
URL infoUrl = null;
InputStream inStream = null;
String line = "";
try {
infoUrl = new URL("http://pv.sohu.com/cityjson?ie=utf-8");
URLConnection connection = infoUrl.openConnection();
HttpURLConnection httpConnection = (HttpURLConnection) connection;
int responseCode = httpConnection.getResponseCode();
if (responseCode == HttpURLConnection.HTTP_OK) {
inStream = httpConnection.getInputStream();
BufferedReader reader = new BufferedReader(new InputStreamReader(inStream, "utf-8"));
StringBuilder strber = new StringBuilder();
while ((line = reader.readLine()) != null)
strber.append(line + "\n");
inStream.close();
// 从反馈的结果中提取出IP地址
int start = strber.indexOf("{");
int end = strber.indexOf("}");
String json = strber.substring(start, end + 1);
if (json != null) {
try {
JSONObject jsonObject = new JSONObject(json);
line = jsonObject.optString("cip");
} catch (JSONException e) {
e.printStackTrace();
}
}
return line;
}
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return line;
}

public static String getLocalMacAddress() {//没有缓存的地址，则查询
String mac_s = ""; try { byte[] mac;
NetworkInterface ne = NetworkInterface.getByInetAddress(InetAddress.getByName(getLocalIpAddress()));
mac = ne.getHardwareAddress();
mac_s = byte2hex(mac);
} catch (Exception e) {
} mac_s; return mac_s;
}

❼ java如何获取客户端mac地址

以下代码实现浏览器中获取mac地址放入一个输入框或隐藏域，随登录信息一起提交到服务器。因为安全级别的关系可能会出现警告，可选择允许执行。长期使用的话建议用户将改站点加入信任站点或把安全级别调低。

❾ 求获取客户端mac地址java代码，急需急需，麻烦了

通过ip获取指定ip地址的mac地址，ip可以通过请求request获取，
request.getRemoteAddr()；
(当然获取ip也不是在任何情况下都有效的)
通过了Apache,Squid等反向代理软件就不能获取到客户端的真实IP地址。
您也许需要通过其他的方式获取，(见附)
//获取mac如下 (nbtstat -A IPAddress是对给定的IP地址解析其主机名。如果不能正常解析它的主机
//名的话，有可能是防火墙屏蔽了。也可能是在DNS中将NetBios 解析选项屏蔽了。)
public String getMACAddress(String ip){
String str = "";
String macAddress = "";
try {
Process p = Runtime.getRuntime().exec("nbtstat -A " + ip);
InputStreamReader ir = new InputStreamReader(p.getInputStream());
LineNumberReader input = new LineNumberReader(ir);
for (int i = 1; i < 100; i++) {
str = input.readLine();
if (str != null) {
if (str.indexOf("MAC Address") > 1) {
macAddress = str.substring(str.indexOf("MAC Address") + 14, str.length());
break;
}
if (str.indexOf("MAC Address") > 1) {
macAddress = str.substring(str.indexOf("MAC 地址") + 14, str.length());
break;
}
//以上有个判断，不同系统cmd命令执行的返回结果展示方式不一样，我测试的win7是MAC 地址
//所以又第二个if判断 你可先在你机器上cmd测试下nbtstat -A 命令 当然得有一个你可以ping通的
//网络ip地址,然后根据你得到的结果中mac地址显示方式来确定这个循环取值

}
}
} catch (IOException e) {
e.printStackTrace(System.out);
}
return macAddress;
}
附：
通过代理了的客户端ip地址获取方式
于是可得出获得客户端真实IP地址的方法一：
public String getRemortIP(HttpServletRequest request) {
if (request.getHeader("x-forwarded-for") == null) {
return request.getRemoteAddr();
}
return request.getHeader("x-forwarded-for");
}

获得客户端真实IP地址的方法二：
public String getIpAddr(HttpServletRequest request) {
String ip = request.getHeader("x-forwarded-for");
if(ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
ip = request.getHeader("Proxy-Client-IP");
}
if(ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
ip = request.getHeader("WL-Proxy-Client-IP");
}
if(ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
ip = request.getRemoteAddr();
}
return ip;
}

可是，如果通过了多级反向代理的话，X-Forwarded-For的值并不止一个，而是一串IP值，究竟哪个才是真正的用户端的真实IP呢？

答案是取X-Forwarded-For中第一个非unknown的有效IP字符串。如：
X-Forwarded-For：192.168.1.110, 192.168.1.120, 192.168.1.130, 192.168.1.100
用户真实IP为： 192.168.1.110
