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

11     private static Boolean isLinux() {
22         String os = System.getProperty("os.name");
33         log.info("os.name: {}", os);
44         return !os.toLowerCase().startsWith("win");
55     }

2. Linux:

　　获取MAC地址:

1 1     private static String getMACAddressByLinux() throws Exception {
2 2         String[] cmd = {"ifconfig"};
3 3 
4 4         Process process = Runtime.getRuntime().exec(cmd);
5 5         process.waitFor();
6 6 
7 7         BufferedReader br = new BufferedReader(new InputStreamReader(process.getInputStream()));
8 8         StringBuffer sb = new StringBuffer();
9 9         String line;
1010         while ((line = br.readLine()) != null) {
1111             sb.append(line);
1212         }
1313 
1414         String str1 = sb.toString();
1515         String str2 = str1.split("ether")[1].trim();
1616         String result = str2.split("txqueuelen")[0].trim();
1717         log.info("Linux MacAddress is: {}", result);
1818         br.close();
1919 
2020         return result;
2121     }

　　获取硬盘序列号:

1 1     private static String getIdentifierByLinux() throws Exception {
2 2         String[] cmd = {"fdisk", "-l"};
3 3 
4 4         Process process = Runtime.getRuntime().exec(cmd);
5 5         process.waitFor();
6 6 
7 7         BufferedReader br = new BufferedReader(new InputStreamReader(process.getInputStream()));
8 8         StringBuffer sb = new StringBuffer();
9 9         String line;
1010         while ((line = br.readLine()) != null) {
1111             sb.append(line);
1212         }
1313 
1414         String str1 = sb.toString();
1515         String str2 = str1.split("identifier:")[1].trim();
1616         String result = str2.split("Device Boot")[0].trim();
1717         log.info("Linux Identifier is: {}", result);
1818         br.close();
1919 
2020         return result;
2121     }

3. Windows:

　　获取MAC地址: (默认获取第一张网卡)

1 1     private static String getMACAddressByWindows() throws Exception {
2 2         String result = "";
3 3         Process process = Runtime.getRuntime().exec("ipconfig /all");
4 4         BufferedReader br = new BufferedReader(new InputStreamReader(process.getInputStream(), "GBK"));
5 5 
6 6         String line;
7 7         int index = -1;
8 8         while ((line = br.readLine()) != null) {
9 9             index = line.toLowerCase().indexOf("物理地址");
1010             if (index >= 0) {// 找到了
1111                 index = line.indexOf(":");
1212                 if (index >= 0) {
1313                     result = line.substring(index + 1).trim();
1414                 }
1515                 break;
1616             }
1717         }
1818         log.info("Windows MACAddress is: {}", result);
1919         br.close();
2020         return result;
2121     }

　　获取硬盘序列号: (默认获取C盘)

1 1     private static String getIdentifierByWindows() throws Exception {
2 2         String result = "";
3 3         Process process = Runtime.getRuntime().exec("cmd /c dir C:");
4 4         BufferedReader br = new BufferedReader(new InputStreamReader(process.getInputStream(), "GBK"));
5 5 
6 6         String line;
7 7         while ((line = br.readLine()) != null) {
8 8             if (line.indexOf("卷的序列号是 ") != -1) {
9 9                 result = line.substring(line.indexOf("卷的序列号是 ") + "卷的序列号是 ".length(), line.length());
1010                 break;
1111             }
1212         }
1313         log.info("Windows Identifier is: {}", result);
1414         br.close();
1515         return result;
1616     }

4. 测试:

1 1     public static void main(String[] a) throws Exception {
2 2         // 判断是Linux还是Windows
3 3         if (isLinux()) {
4 4             // Linux操作系统
5 5             String macAddress = getMACAddressByLinux();
6 6             System.out.println("Linux macAddress: " + macAddress);
7 7             String Identifier = getIdentifierByLinux();
8 8             System.out.println("Linux Identifier: " + Identifier);
9 9         } else {
1010             // Windows操作系统
1111             String macAddress = getMACAddressByWindows();
1212             System.out.println("Windows macAddress: " + macAddress);
1313             String Identifier = getIdentifierByWindows();
1414             System.out.println("Windows Identifier: " + Identifier);
1515         }
1616     }

 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:

1 javac -encoding UTF-8 Test.java
