前提：用户不会去反编译class文件

绑定IP/网卡地址,先获取MAC地址

import java.net.InetAddress;
import java.io.InputStream;

import java.io.IOException;
import java.text.ParseException;
import java.util.StringTokenizer;

public class NetworkInfo
{
//get IP Address (only for winzk series OS)
public static String getMacAddress() throws IOException
{
String os = System.getProperty("os.name");
try
{
if (os.startsWith("Windows"))
{
return windowsParseMacAddress(windowsRunIpConfigCommand());
}
else
{
throw new IOException("unknown operating system: " + os);
}
}
catch (ParseException ex)
{
ex.printStackTrace();
throw new IOException(ex.getMessage());
}
}

public static void main(String[] args)
{
try
{
//System.out.println("UUID = " + NetworkInfo.getMacAddress());
System.out.println(getMacAddress("202.104.32.198"));
}
catch( Exception e )
{
System.out.println(e);
}
}

{

System.out.println( "IPA_ddress = " + localHost );
return lastMacAddress;
}

if (windowsIsMacAddress(macAddressCandidate))
{

continue;
}
}
ParseException ex = new ParseException("cannot read MAC address from [" + ipConfigResponse + "]", 0);
ex.printStackTrace();
throw ex;
}

private final static boolean windowsIsMacAddress(String macAddressCandidate)
{
// TODO: use a smart regular expression
if (macAddressCandidate.length() != 17)
return false;
return true;
}

private final static String windowsRunIpConfigCommand() throws IOException
{
//run the command "ipconfig /all" in order to get the MAC INFO;
Process p = Runtime.getRuntime().exec("ipconfig /all");
InputStream stdoutStream = new BufferedInputStream(p.getInputStream());
StringBuffer buffer= new StringBuffer();
for (;;)
{
int c = stdoutStream.read();
if (c == -1)
break;
buffer.append((char)c);
}
String outputText = new String((buffer.toString().getBytes("ISO8859_1")), "GB2312");
stdoutStream.close();
System.out.println("outputText = " + outputText );
return outputText;
}

private final static String getMacAddress(String remotePcIP)
{
String str="";
String macAddress="";
try
{
Process pp= Runtime.getRuntime().exec ("nbtstat -A " + remotePcIP);
InputStreamReader ir = new InputStreamReader(pp.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;
}
}
}
}

catch (IOException ex)
{
}
return macAddress;
}

}

然后在servlet里面绑定!不用多说了哦:)
