//Java獲得CPU序列號和網卡Mac地址

/*

利用Runtime call操作系統的命令，具體的命令取決于不同的操作系統，注意不要調用Runtime.getRuntime().exec(String)接口，要用Runtime.getRuntime().exec(String[])這個接口，不然復雜命令的執行會有問題。例子如下(拿cpu個數，其他類似)：

定義命令：

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"};

然后判斷系統：

os = System.getProperty("os.name").toLowerCase();

根據不同的操作系統call不同的命令。
