Java获取客户端IP地址、MAC地址，根据IP获取地理位置信息代码

获取IP地址：

/**
	 * 获取用户端的IP地址
	 */
	public String getRealUserIP(HttpServletRequest request) {
        String ip = request.getHeader("X-Forwarded-For");
        if(!StringUtils.isEmpty(ip) && !"unKnown".equalsIgnoreCase(ip)){
            //多次反向代理后会有多个ip值，第一个ip才是真实ip
            int index = ip.indexOf(",");
            if(index != -1){
                return ip.substring(0,index);
            }else{
                return ip;
            }
        }
        ip = request.getHeader("X-Real-IP");
        if(!StringUtils.isEmpty(ip) && !"unKnown".equalsIgnoreCase(ip)){
            return ip;
        }
        return request.getRemoteAddr();
    }

获取MAC地址：

方法1、

/**
     * 根据IP获取MAC地址(该方法仅支持win7系统 TODO)
     */
    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") > -1) {
                        macAddress = str.substring(str.indexOf("=") + 1, str.length()).trim();
                        break;
                    }
                }
            }
        }
        catch (IOException e) {
            e.printStackTrace(System.out);
        }
        return macAddress;
    }

方法2、

/**
	 * 获取MAC地址
	 */
	public String getMAC() {
        String mac = null;
        try {
            Process pro = Runtime.getRuntime().exec("cmd.exe /c ipconfig/all");
 
            InputStream is = pro.getInputStream();
            BufferedReader br = new BufferedReader(new InputStreamReader(is));
            String message = br.readLine();
 
            int index = -1;
            while (message != null) {
                if ((index = message.indexOf("Physical Address")) > 0) {
                    mac = message.substring(index + 36).trim();
                    break;
                }
                message = br.readLine();
            }
            System.out.println(mac);
            br.close();
            pro.destroy();
        } catch (IOException e) {
            System.out.println("Can't get mac address!");
            return null;
        }
        return mac;
    }

方法3、

/**
	 * 获取MAC地址
	 */
	public String getMac2(String ip){  
		String mac = "";
        try {  
        Process p = Runtime.getRuntime().exec("arp -n");  
            InputStreamReader ir = new InputStreamReader(p.getInputStream());  
            LineNumberReader input = new LineNumberReader(ir);  
            p.waitFor();  
            boolean flag = true;  
            String ipStr = "(" + ip + ")";  
            while(flag) {  
                String str = input.readLine();  
                if (str != null) {  
                    if (str.indexOf(ipStr) > 1) {  
                        int temp = str.indexOf("at");  
                        mac = str.substring(  
                        temp + 3, temp + 20);  
                        break;  
                    }  
                } else  
                flag = false;  
            }  
        } catch (IOException | InterruptedException e) {  
            e.printStackTrace(System.out);  
        }  
        return mac;  
    }
