远程ip是 192.168.1.28

public class GetMacByIp {
        
    
        public static void main(String[] args) throws UnknownHostException, SocketException {
        
    
            String ip = "192.168.1.28";
            String localMac = getLocalMac(ip);
            System.out.println(localMac);
        }
        public static String getLocalMac(String ipAddress){
        
            String str = "";
            String macAddress = "";
                // 获取非本地IP的MAC地址
                try {
        
                    System.out.println(ipAddress);
                    Process p = Runtime.getRuntime()
                            .exec("nbtstat -A " + ipAddress);
                    System.out.println("===process==" + p);
    
                    InputStreamReader ir = new InputStreamReader(p.getInputStream());
    
                    BufferedReader br = new BufferedReader(ir);
    
                    while ((str = br.readLine()) != null) {
        
                        if (str.indexOf("MAC") > 1) {
        
                            macAddress = str.substring(str.indexOf("MAC") + 9, str.length());
                            macAddress = macAddress.trim();
                            System.out.println("macAddress:" + macAddress);
                            break;
                        }
                    }
                    p.destroy();
                    br.close();
                    ir.close();
                } catch (IOException ex) {
        
                }
                return macAddress;
            }
    }
