使用JAVA获取客户端MAC地址

//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。
