//Java獲得CPU序列號(hào)和網(wǎng)卡Mac地址
/*
利用Runtime call操作系統(tǒng)的命令，具體的命令取決于不同的操作系統(tǒng)，注意不要調(diào)用Runtime.getRuntime().exec(String)接口，要用Runtime.getRuntime().exec(String[])這個(gè)接口，不然復(fù)雜命令的執(zhí)行會(huì)有問題。例子如下（拿cpu個(gè)數(shù)，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(tǒng)：
os = System.getProperty("os.name").toLowerCase();

根據(jù)不同的操作系統(tǒng)call不同的命令。
