在Windows或者Linux操作系統中，獲取多網卡信息，可通過執行命令方式獲取，具體如下：

public Vector getServerIps()

{

Vector address = new Vector();

String linuxKey = "inet";

String window7Key = "IPv4";

String windowKey = "IP Address";

String os = System.getProperty("os.name");

if (os != null)

{

if (os.startsWith("Windows"))

{

try

{

ProcessBuilder pb = new ProcessBuilder("ipconfig", "/all");

Process p = pb.start();

BufferedReader br = new BufferedReader(

new InputStreamReader(p.getInputStream()));

String line;

while ((line = br.readLine()) != null)

{

if ((line.indexOf(window7Key) != -1)

|| (line.indexOf(windowKey) != -1))

{

int index = line.indexOf(":");

int indexLast = line.indexOf("(");

String sbstr = null;

if (indexLast == -1)

{

sbstr = line.substring(index + 1).trim();

}

else

{

sbstr = line.substring(index + 1, indexLast).trim();

}

if (!sbstr.equals("127.0.0.1"))

{

address.add(sbstr);

}

}

}

br.close();

return address;

}

catch (IOException e)

{

String localIp = "";

try

{

String localHost = InetAddress.getLocalHost().toString();

localIp = localHost.split("/")[1];

}

catch (UnknownHostException ex)

{

localIp = "127.0.0.1";

}

address.add(localIp);

}

}

else if (os.startsWith("Linux"))

{

try

{

ProcessBuilder pb = new ProcessBuilder("ifconfig");

Process p = pb.start();

BufferedReader br = new BufferedReader(new InputStreamReader(p.getInputStream()));

String line;

while ((line = br.readLine()) != null)

{

if (line.indexOf(linuxKey) != -1)

{

int index = line.indexOf(":");

String sbstr = line.substring(index + 1).trim();

if (!sbstr.equals("127.0.0.1"))

{

address.add(sbstr);

}

}

}

br.close();

return address;

}

catch (IOException ex)

{

String localIp = "";

try

{

String localHost = InetAddress.getLocalHost().toString();

localIp = localHost.split("/")[1];

}

catch (UnknownHostException eu)

{

localIp = "127.0.0.1";

}

address.add(localIp);

}

}

}

return address;
