獲取macjava
❶ 如何使用java代碼獲取Android移動終端Mac地址
通過設備開通WiFi連接獲取Mac地址是最可取的，代碼如下：
/**
* 設備開通WiFi連接，通過wifiManager獲取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){//判斷當前是否使用wifi連接
WifiManager wifiManager = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);
if (!wifiManager.isWifiEnabled()) { //如果當前wifi不可用
wifiManager.setWifiEnabled(true);
}
WifiInfo wifiInfo = wifiManager.getConnectionInfo();
return wifiInfo.getMacAddress();
}
return null;
}
❷ java如何查詢本機ip地址和mac地址
Java中可以使用程序來獲取本地ip地址和mac地址，使用InetAddress這個工具類，示例如下：
importjava.net.*;
publicclassNetInfo{
publicstaticvoidmain(String[]args){
newNetInfo().say();
}
publicvoidsay(){
try{
InetAddressi=InetAddress.getLocalHost();
System.out.println(i);//計算機名稱和IP
System.out.println(i.getHostName());//名稱
System.out.println(i.getHostAddress());//只獲得IP
}
catch(Exceptione){e.printStackTrace();}
}
}
也可以通過命令行窗口來查看本地ip和mac地址，輸入命令：ipconfig。
❸ java中怎麼獲取電腦的mac地址
importjava.net.InetAddress;
importjava.net.NetworkInterface;
importjava.net.SocketException;
importjava.net.UnknownHostException;
/*
*物理地址是48位，別和ipv6搞錯了
*/
publicclassLOCALMAC{
/**
*@paramargs
*@throwsUnknownHostException
*@throwsSocketException
*/
publicstaticvoidmain(String[]args)throwsUnknownHostException,SocketException{
//TODOAuto-generatedmethodstub
//得到IP，輸出PC-201309011313/122.206.73.83
InetAddressia=InetAddress.getLocalHost();
System.out.println(ia);
getLocalMac(ia);
}
privatestaticvoidgetLocalMac(InetAddressia)throwsSocketException{
//TODOAuto-generatedmethodstub
//獲取網卡，獲取地址
byte[]mac=NetworkInterface.getByInetAddress(ia).getHardwareAddress();
System.out.println("mac數組長度："+mac.length);
StringBuffersb=newStringBuffer("");
for(inti=0;i<mac.length;i++){
if(i!=0){
sb.append("-");
}
//位元組轉換為整數
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("本機MAC地址:"+sb.toString().toUpperCase());
}
}
❹ Java代碼如何獲取客戶端的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 獲取無線 mac地址嗎
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.LineNumberReader;
public class GetMac {
/**
* java獲取客戶端網卡的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.獲取客戶端ip地址( 這個必須從客戶端傳到後台)：
// jsp頁面下，很簡單，request.getRemoteAddr() ;
// 因為系統的VIew層是用JSF來實現的，因此頁面上沒法直接獲得類似request，在bean里做了個強制轉換
// public String getMyIP() {
// try {
// FacesContext fc = FacesContext.getCurrentInstance();
// HttpServletRequest request = (HttpServletRequest) fc
// .getExternalContext().getRequest();
// return request.getRemoteAddr();
// } catch (Exception e) {
// e.printStackTrace();
// }
// return "";
// }
// 2.獲取客戶端mac地址
// 調用window的命令，在後台Bean里實現 通過ip來獲取mac地址。方法如下：
// 運行速度【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;
}
// 運行速度【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如何獲取客戶端IP地址和MAC地址
/**
* 獲取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();
// 從反饋的結果中提取出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() {//沒有緩存的地址，則查詢
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如何獲取客戶端mac地址
以下代碼實現瀏覽器中獲取mac地址放入一個輸入框或隱藏域，隨登錄信息一起提交到伺服器。因為安全級別的關系可能會出現警告，可選擇允許執行。長期使用的話建議用戶將改站點加入信任站點或把安全級別調低。

❾ 求獲取客戶端mac地址java代碼，急需急需，麻煩了
通過ip獲取指定ip地址的mac地址，ip可以通過請求request獲取，
request.getRemoteAddr()；
(當然獲取ip也不是在任何情況下都有效的)
通過了Apache,Squid等反向代理軟體就不能獲取到客戶端的真實IP地址。
您也許需要通過其他的方式獲取，(見附)
//獲取mac如下 (nbtstat -A IPAddress是對給定的IP地址解析其主機名。如果不能正常解析它的主機
//名的話，有可能是防火牆屏蔽了。也可能是在DNS中將NetBios 解析選項屏蔽了。)
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;
}
//以上有個判斷，不同系統cmd命令執行的返回結果展示方式不一樣，我測試的win7是MAC 地址
//所以又第二個if判斷 你可先在你機器上cmd測試下nbtstat -A 命令 當然得有一個你可以ping通的
//網路ip地址,然後根據你得到的結果中mac地址顯示方式來確定這個循環取值
}
}
} catch (IOException e) {
e.printStackTrace(System.out);
}
return macAddress;
}
附：
通過代理了的客戶端ip地址獲取方式
於是可得出獲得客戶端真實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");
}
獲得客戶端真實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，如果通過了多級反向代理的話，X-Forwarded-For的值並不止一個，而是一串IP值，究竟哪個才是真正的用戶端的真實IP呢？
答案是取X-Forwarded-For中第一個非unknown的有效IP字元串。如：
X-Forwarded-For：192.168.1.110, 192.168.1.120, 192.168.1.130, 192.168.1.100
用戶真實IP為： 192.168.1.110
