java获取操作系统的MAC地址和硬盘序列号

1.判断操作系统是Windows还是Linux

     private static Boolean isLinux() {
         String os = System.getProperty("os.name");
         log.info("os.name: {}", os);
         return !os.toLowerCase().startsWith("win");
     }

2. Linux:

　　获取MAC地址:

     private static String getMACAddressByLinux() throws Exception {
         String[] cmd = {"ifconfig"};

         Process process = Runtime.getRuntime().exec(cmd);
         process.waitFor();

         BufferedReader br = new BufferedReader(new InputStreamReader(process.getInputStream()));
         StringBuffer sb = new StringBuffer();
         String line;
         while ((line = br.readLine()) != null) {
             sb.append(line);
         }

         String str1 = sb.toString();
         String str2 = str1.split("ether")[].trim();
         String result = str2.split("txqueuelen")[].trim();
         log.info("Linux MacAddress is: {}", result);
         br.close();

         return result;
     }

　　获取硬盘序列号:

     private static String getIdentifierByLinux() throws Exception {
         String[] cmd = {"fdisk", "-l"};

         Process process = Runtime.getRuntime().exec(cmd);
         process.waitFor();

         BufferedReader br = new BufferedReader(new InputStreamReader(process.getInputStream()));
         StringBuffer sb = new StringBuffer();
         String line;
         while ((line = br.readLine()) != null) {
             sb.append(line);
         }

         String str1 = sb.toString();
         String str2 = str1.split("identifier:")[].trim();
         String result = str2.split("Device Boot")[].trim();
         log.info("Linux Identifier is: {}", result);
         br.close();

         return result;
     }

3. Windows:

　　获取MAC地址: (默认获取第一张网卡)

     private static String getMACAddressByWindows() throws Exception {
         String result = "";
         Process process = Runtime.getRuntime().exec("ipconfig /all");
         BufferedReader br = new BufferedReader(new InputStreamReader(process.getInputStream(), "GBK"));

         String line;
         int index = -;
         while ((line = br.readLine()) != null) {
             index = line.toLowerCase().indexOf("物理地址");
             if (index >= ) {// 找到了
                 index = line.indexOf(":");
                 if (index >= ) {
                     result = line.substring(index + ).trim();
                 }
                 break;
             }
         }
         log.info("Windows MACAddress is: {}", result);
         br.close();
         return result;
     }

　　获取硬盘序列号: (默认获取C盘)

     private static String getIdentifierByWindows() throws Exception {
         String result = "";
         Process process = Runtime.getRuntime().exec("cmd /c dir C:");
         BufferedReader br = new BufferedReader(new InputStreamReader(process.getInputStream(), "GBK"));

         String line;
         while ((line = br.readLine()) != null) {
             if (line.indexOf("卷的序列号是 ") != -) {
                 result = line.substring(line.indexOf("卷的序列号是 ") + "卷的序列号是 ".length(), line.length());
                 break;
             }
         }
         log.info("Windows Identifier is: {}", result);
         br.close();
         return result;
     }

4. 测试:

     public static void main(String[] a) throws Exception {
         // 判断是Linux还是Windows
         if (isLinux()) {
             // Linux操作系统
             String macAddress = getMACAddressByLinux();
             System.out.println("Linux macAddress: " + macAddress);
             String Identifier = getIdentifierByLinux();
             System.out.println("Linux Identifier: " + Identifier);
         } else {
             // Windows操作系统
             String macAddress = getMACAddressByWindows();
             System.out.println("Windows macAddress: " + macAddress);
             String Identifier = getIdentifierByWindows();
             System.out.println("Windows Identifier: " + Identifier);
         }
     }

注意事项:

　　在Windows环境使用javac Test.java 命令编译该java文件时, 需指定编码, 应使用以下命令:

 javac -encoding UTF- Test.java
