1. java web 怎麼得到客戶端的 Mac 地址
獲取不到的，mac地址還在ip地址的底層，java沒辦法深入底層去獲取。
2. java伺服器怎麼獲取客戶端請求的mac
獲取 Mac 只能在本地網路里才能獲取，過了路由器就不能獲取了
3. java如何獲取mac地址
解釋說明可參考代碼中的注釋即可：
import java.io.BufferedReader;
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;
}
}
4. 如何用Java獲取客戶端MAC地址
我來幫助你
public static void main(String[] arguments) throws Exception {
InetAddress ia = InetAddress.getLocalHost();// 獲取本地IP對象
System.out.println("MAC ......... " + getMACAddress(ia));
}
// 獲取MAC地址的方法
private static String getMACAddress(InetAddress ia) throws Exception {
// 獲得網路介面對象（即網卡），並得到mac地址，mac地址存在於一個byte數組中。
byte[] mac = NetworkInterface.getByInetAddress(ia).getHardwareAddress();
// 下面代碼是把mac地址拼裝成String
StringBuffer sb = new StringBuffer();
for (int i = 0; i < mac.length; i++) {
if (i != 0) {
sb.append("-");
}
// mac[i] & 0xFF 是為了把byte轉化為正整數
String s = Integer.toHexString(mac[i] & 0xFF);
sb.append(s.length() == 1 ? 0 + s : s);
}
// 把字元串所有小寫字母改為大寫成為正規的mac地址並返回
return sb.toString().toUpperCase();
}
還望採納！
5. 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;
}
6. 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; }
7. 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。

8. Java獲取客戶端所有的mac地址，是所有的，還有是客戶端的，而不是服務端的
想要獲取客戶端的MAC，目前的瀏覽器，只有用控制項了。activex或者flash

10. Java web 怎麼得到客戶端的Mac地址
這個跟瀏覽器有關,你的js許可權要向瀏覽器申請,瀏覽器向操作系統申請
現在的瀏覽器並沒有開放這個許可權.
解決辦法1:用C++寫GUI,調用操作系統的API,獲取mac地址,每個操作系統的API是不一樣的.
解決辦法2:自己寫一個瀏覽器,並且寫好js的api,然後瀏覽器去請求系統調用,獲得mac地址.
所謂的active插件一樣也是向操作系統申請了api獲取的
