Java 原生代码获取服务器的网卡 Mac 地址、CPU序列号、主板序列号-编程知识

Java 原生代码获取服务器的网卡 Mac 地址、CPU序列号、主板序列号

1、概述

Java 可以获取服务器的网卡 Mac 地址、CPU 序列号、主板序列号等信息，用来做一些软件授权验证、设备管理等场景。

2、代码实现

package com.study.util;import java.net.InetAddress;
import java.net.NetworkInterface;
import java.util.Scanner;/*** @author CSDN 流放深圳* @description 获取本机相关地址工具类* @create 2024-04-13 15:17* @since 1.0.0*/
public class MachineAddrUtil {/*** 获取网卡物理地址工具类** @return*/public static String getMac() {String result = null;try {NetworkInterface networkInterface = NetworkInterface.getByInetAddress(InetAddress.getLocalHost());byte[] macByte = networkInterface.getHardwareAddress();StringBuilder sb = new StringBuilder();for (int i = 0; i < macByte.length; i++) {sb.append(String.format("%02X%s", macByte[i], (i < macByte.length - 1) ? "-" : ""));}result = sb.toString();} catch (Exception e) {e.printStackTrace();}return result;}/*** 获取 CPU 序列号** @return*/public static String getCPUSerial() {String cpuSerial = System.getenv("PROCESSOR_IDENTIFIER");return cpuSerial;}/*** 获取主板序列号** @return*/public static String getMainBoardSerial() {String result = null;try {Process process = Runtime.getRuntime().exec(new String[]{"wmic", "baseboard", "get", "serialnumber"});process.getOutputStream().close();Scanner scanner = new Scanner(process.getInputStream());while (scanner.hasNext()) {result = scanner.next();}} catch (Exception e) {e.printStackTrace();}return result;}/*** 测试* @param args*/public static void main(String[] args) {System.out.println("本机的【网卡物理地址】=" + getMac());System.out.println("本机的【CPU 序列号】=" + getCPUSerial());System.out.println("本机的【主板序列号】=" + getMainBoardSerial());}}

测试结果：
