方法一:
调用Windows的DOS命令,从输出结果中读取MAC地址:
public static String getMACAddress() {
String address = "";
String os = System.getProperty("os.name");
if ( os != null && os.startsWith("Windows")) {
try {
String command = "cmd.exe /c ipconfig /all";
Process p = Runtime.getRuntime().exec(command);
BufferedReader br =
new BufferedReader(
new InputStreamReader(p.getInputStream()));
String line;
while ((line = br.readLine()) != null) {
if (line.indexOf("Physical Address") > 0) {
int index = line.indexOf(":");
index += 2;
address = line.substring(index);
break;
}
}
br.close();
return address.trim();
}
catch (IOException e) { }
}
return address;
}
We can replace the "ipconfig" to "ping x.x.x.x" and "arp -a"...We can get the mac list...haha!!
缺点:只能取得服务器端MAC地址.如果要取得客户端的MAC地址,需用Applet.只针对MS-WIN系统.
方法二:
可以用JS或vbscript来调用WMI接口来获取Client端的MAC地址.

<head>
<title>WMI Scripting HTML</title>
<script FOR="foo" EVENT="OnCompleted(hResult,pErrorObject, pAsyncContext)" LANGUAGE="JScript">
document.forms[0].txtMACAddr.value=unescape(MACAddr);
document.forms[0].txtIPAddr.value=unescape(IPAddr);
document.forms[0].txtDNSName.value=unescape(sDNSName);
//document.formbar.submit();
</script>
<script FOR="foo" EVENT="OnObjectReady(objObject,objAsyncContext)" LANGUAGE="JScript">
if(objObject.IPEnabled != null && objObject.IPEnabled != "undefined" && objObject.IPEnabled == true)
{
if(objObject.MACAddress != null && objObject.MACAddress != "undefined")
MACAddr = objObject.MACAddress;
if(objObject.IPEnabled
&& objObject.IPAddress(0) != null &&
objObject.IPAddress(0) != "undefined")
IPAddr = objObject.IPAddress(0);
if(objObject.DNSHostName != null && objObject.DNSHostName != "undefined")
sDNSName = objObject.DNSHostName;
}
</script>
</head>
<body>
<object classid="CLSID:76A64158-CB41-11D1-8B02-00600806D9B6" id="locator" VIEWASTEXT>
</object>
<object classid="CLSID:75718C9A-F029-11d1-A1AC-00C04FB6C223" id="foo">
</object>
<script LANGUAGE="JScript">
var service = locator.ConnectServer();
var MACAddr ;
var IPAddr ;
var DomainAddr;
var sDNSName;
service.Security_.ImpersonationLevel=3;
service.InstancesOfAsync(foo, ‘Win32_NetworkAdapterConfiguration‘);
</script>
<form method="POST" action="NICPost.asp" id="formfoo" name="formbar">
<input type=text name="txtMACAddr">
<input type=text name="txtIPAddr">
<input type=text name="txtDNSName">
</form>
</body>
</html>
关于WMI的详细信息可以参看MSDN:

平心而论，WMI的很强大的。原先需要动用重量级编程工具才能做到的事，现在用js/vbscript就可以做了。
获取多块网卡的MAC地址:
if(objObject.MACAddress != null && objObject.MACAddress != "undefined"){
MACAddr = objObject.MACAddress;
alert( MACAddr );
}
缺点:需要ActiveX支持.对MS-WIN系统有效.
方法三:
想137口发送UDP查询:
WINDOWS平台的客户端(当获取时它转换为服务端角色),NETBIOS协议在137口上,我们只要向它的137口发送UDP查询,获取它的返回值就可以获取到它所有的网卡地址
