上代码:


首先,通过HttpServletRequest类获取到request:

HttpServletRequest request = ServletActionContext.getRequest();

然后,调用request.getRemoteAddr()取到客户端IP地址:

String IP=request.getRemoteAddr();

最后,调用getMACAddress(IP)函数得到客户端的Mac地址:
macaddress = getMACAddress(IP);//根据IP地址获取服务器端的MAC地址System.out.println("-----------------------客户端MACAddress== "+getMACAddress(IP));


public String getMACAddress(String ip) {String str = "";String macAddress = "";try {Process p = Runtime.getRuntime().exec("nbtstat -A " + ip);InputStreamReader ir = new InputStreamReader(p.getInputStream());LineNumberReader input = new LineNumberReader(ir);for (int i = 1; i < 100; i++) {str = input.readLine();if (str != null) {if (str.indexOf("MAC 地址") > 1) {//客户端使用的是中文版操作系统macAddress = str.substring(str.indexOf("MAC 地址") + 9, str.length());break;}else if(str.indexOf("MAC Address") > 1){//客户端使用的是英文版操作系统macAddress = str.substring(str.indexOf("MAC Address") + 14, str.length());break;}}}} catch (IOException e) {e.printStackTrace(System.out);}return macAddress;}

运行结果:


-----------------------客户端MACAddress== 0C-82-68-40-AC-F4


马到成功!
