* 注意事项:
* ① 通过执行vbs 脚本(基于微软 Visual Basic的脚本语言) 来获取信息的方式只适用于windows系统,因为这种方式极度依赖 Windows脚本宿主环境的支持
* ② 关于临时目录,可通过 System.getProperty("java.io.tmpdir") 获取其具体位置。在window下通常为 C:\Users\Administrator\AppData\Local\Temp ,linux系统 下为 /tmp
* ③ 命令方式和执行vbs 脚本的方式获取到的磁盘序列号并不相同,具体哪个是真实的序列号,有待验证
* ④ 或可尝试通过arp 命令来获取物理地址,但是arp查询的是高速缓存表的IP-MAC映射关系,包括了网络中与本机通信过的所有主机的MAC-IP映射关系(你可以ping一下远程主机建立相应的映射关系缓存),获取的地址信息或显得过于庞杂
* ⑤ 针对 Linux 系统主要通过执行命令的方式,不过由于系统架构的差异性,不同平台对同样的命令不一定都支持,需要根据具体系统测试、做兼容,这里提供一些常用查看命令——
* MAC 地址:ip link | grep link/ether | awk '{print $2}'
* 磁盘序列号 hdparm -i /dev/sda | grep SerialNo 或 lsblk -a -o SERIAL
* CPU序列号 dmidecode -t processor | grep 'ID'
