Java获得CPU序列号和网卡Mac地址

/**
 * 利用Runtime call操作系统的命令，具体的命令取决于不同的操作系统，注意不要调用Runtime.getRuntime().exec(String)接口，要用Runtime.getRuntime().exec(String[])这个接口，不然复杂命令的执行会有问题。例子如下（拿cpu个数，其他类似）：
 * 定义命令：
 * WindowsCmd ="cmd.exe /c echo %NUMBER_OF_PROCESSORS%";//windows的特殊
 * SolarisCmd = {"/bin/sh", "-c", "/usr/sbin/psrinfo | wc -l"};
 * AIXCmd = {"/bin/sh", "-c", "/usr/sbin/lsdev -Cc processor | wc -l"};
 * HPUXCmd = {"/bin/sh", "-c", "echo \"map\" | /usr/sbin/cstm | grep CPU | wc -l "};
 * LinuxCmd = {"/bin/sh", "-c", "cat /proc/cpuinfo | grep ^process | wc -l"};
 *
 * 然后判断系统：
 * os = System.getProperty("os.name").toLowerCase();
 *
 * 根据不同的操作系统call不同的命令。
