生成机器码

首先需要在后端写个获取window或linux的机器码，根据CPU序列号和硬盘序列号(Windows)，拼接得到

/*** 操作系统的工具类*/
public class OSUtils {/*** 获取window or linux机器码** @return*/public static String getOSNumber() {Map<String, Object> codeMap = new HashMap<>(2);String result = "";if (isWindows()) {String processorId = getCPUSerialNumber();codeMap.put("pid", processorId);String serialNumber = getHardDiskSerialNumber();codeMap.put("snm", serialNumber);String codeMapStr = JSON.toJSONString(codeMap);String serials = Md5Utils.md5(codeMapStr, SALT);result = getSplitString(serials, "-", 8);} else {codeMap.put("hmi", getHostMachineId());codeMap.put("nwi", getContainerNetworkId());String codeMapStr = JSON.toJSONString(codeMap);String serials = Md5Utils.md5(codeMapStr, SALT);result = getSplitString(serials, "-", 8);}return result;}/*** 获取CPU序列号** @return* @throws IOException*/public static String getCPUSerialNumber() {String next;try {Process process = Runtime.getRuntime().exec(new String[]{"wmic", "cpu", "get", "ProcessorId"});process.getOutputStream().close();Scanner sc = new Scanner(process.getInputStream());String serial = sc.next();next = sc.next();} catch (IOException e) {throw new RuntimeException("获取CPU序列号失败");}return next;}/*** 获取 硬盘序列号(Windows)** @return* @throws IOException* @throws InterruptedException*/public static String getHardDiskSerialNumber() {try {Process process = Runtime.getRuntime().exec(new String[]{"wmic", "path", "win32_physicalmedia", "get", "serialnumber"});process.getOutputStream().close();Scanner sc = new Scanner(process.getInputStream());String serial = sc.next();return sc.next();} catch (IOException e) {throw new RuntimeException("获取硬盘序列号失败");}}/*** 获取系统序列号(linux)** @return*/public static String getHostMachineId() {try {Path path = Paths.get("/etc/machine-id");if (Files.exists(path)) {String content = new String(Files.readAllBytes(path));if (!content.isEmpty()) {return content;}}} catch (Exception e) {System.out.println("获取序列号失败: " + e.getMessage());}return "unknown_host_id";}public static String getContainerNetworkId() {String interfaceName = "eth0"; // 默认网卡名称（可配置化）try {Path addressPath = Paths.get("/sys/class/net/" + interfaceName + "/address");if (Files.exists(addressPath)) {String mac = new String(Files.readAllBytes(addressPath));return mac.replace(":", ""); // 去除冒号，简化格式}} catch (Exception e) {e.printStackTrace();}return "unknown_mac";}private static String getSplitString(String str, String split, int length) {int len = str.length();StringBuilder temp = new StringBuilder();for (int i = 0; i < len; i++) {if (i % length == 0 && i > 0) {temp.append(split);}temp.append(str.charAt(i));}return temp.toString();}public static boolean isWindows() {return System.getProperty("os.name").toLowerCase().contains("windows");}
}

这块写好后再启动程序写打印机器码

都写好后就可以打包上传服务器，在服务器内编译生成服务器的机器码，获取保存下来

public static void main(String[] args) {System.out.println("机器码：" + OSUtils.getOSNumber());// System.setProperty("spring.devtools.restart.enabled", "false");SpringApplication.run(YanfanApplication.class, args);}

生成公钥、私钥、授权码

把下面这段在自己的工具类里找个地方写，写aes加密，机器码＋时间的，执行这个main方法，打包的时候不要打包进去，会被反编译

public static void main(String[] args) throws Exception {// 1. 生成密钥对KeyPair keyPair = RSAUtils.generateKeyPair();PublicKey publicKey = keyPair.getPublic();PrivateKey privateKey = keyPair.getPrivate();// 2. 获取密钥字符串（模拟存储/传输）String publicKeyStr = RSAUtils.getPublicKeyString(publicKey);String privateKeyStr = RSAUtils.getPrivateKeyString(privateKey);// 公钥:// publicKeyStr = "";System.out.println("publicKeyStr: " + publicKeyStr);// 私钥: 不要将自己的私钥放到这里！！！！！// privateKeyStr = "";System.out.println("privateKeyStr: " + privateKeyStr);// 私钥加密，私钥自己保留String data = RSAUtils.encryptWithPrivateKey(OS_NUMBER + "2099-12-31 23:59:59", RSAUtils.getPrivateKey(privateKeyStr));
//        String data = RSAUtils.encryptWithPrivateKey("038e-1ee5-ee15-4005-18ce-15b7-312d-78ee" + "2099-12-31 23:59:59", RSAUtils.getPrivateKey(privateKeyStr));
//        String data = RSAUtils.encryptWithPrivateKey(
//                "038e-1ee5-ee15-4005-18ce-15b7-312d-78ee" + "2025-06-25 23:59:59",
//                RSAUtils.getPrivateKey(privateKeyStr)
//        );System.out.println(data);// 公钥解密，公钥提供给客户System.out.println(RSAUtils.decryptWithPublicKey(data, RSAUtils.getPublicKey(publicKeyStr)));}

私钥自己保存好，公钥放在服务器客户端，授权码放在数据库sys_config，看下面

服务器修改客户端公钥

生成的公钥需要粘到服务器的private-key授权码对应的密钥

授权码找到系统数据库的sys_config表内

全部改好后，写一个授权码监听事件，到期系统自动停止

如果想要测试本地是否执行成功的，把监听事件关闭，但是上传服务器的时候要打开，不然授权码这个写了也没用

/*** 授权码监听事件*/
@Component
@Slf4j
@Order(0)
public class AuthOSValidListener implements ApplicationRunner {@Overridepublic void run(ApplicationArguments args) throws Exception {// 启用授权码功能validate();}public void validate() {// 开启验证机器码new AuthOsValidUtil().verification();}@Scheduled(cron = "0 0/10 * * * ?")   //10执行一次private void validateTime() {validate();}
}
