项目中需要获取服务器系统序列号，方法如下：

/**
         * Method for get Linux Machine MotherBoard Serial Number
         *
         * @return
         */
        public String getLinuxMotherBoardSerialNumber()
        {
            String command = "dmidecode -t system";
            String sn = null;
            Reader reader = null;
            BufferedReader sNumReader = null;
            InputStream inputStream = null;
            List<String> cmdOutput = new ArrayList<>();
            String line = null;
            try
            {
                Process SerNumProcess = Runtime.getRuntime().exec(command);
                inputStream = SerNumProcess.getInputStream();
                reader = new InputStreamReader(inputStream);
                sNumReader = new BufferedReader(reader);
    
                while ((line = sNumReader.readLine()) != null)
                {
                    cmdOutput.add(line);
                }
                LOGGER.info("cmdOutput is {}", cmdOutput);
                if (!CollectionUtils.isEmpty(cmdOutput))
                {
                    for (String output : cmdOutput)
                    {
                        if (output.contains("Serial Number"))
                        {
                            sn = output;
                        }
                    }
                }

                {
                    sn = sn.replaceAll(" ", "");
                    String[] ss = sn.split(":");
                    List<String> sList = Arrays.asList(ss);
                    if (!CollectionUtils.isEmpty(sList))
                    {
                        for (String s : sList)
                        {
                            if (!s.contains("Serial"))
                            {

                        }
                    }
                }
                SerNumProcess.waitFor();
                return sn;
            }
            catch (Exception ex)
            {
                LOGGER.error("Linux Motherboard Exp : " + ex.getMessage());
                return sn;
            }
            finally
            {
                try
