使用JAVA获取客户端MAC地址

1、使用JAVA获取客户端MA（地址/Java获得CPU序列号和网卡Mac地址/*利用Runtimecall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/cecho%NUMBER_OF_PROCESSORS%;/windc的特殊SolarisCmd=/bin/sh,-c,/usr/sbin/psrinfo|wc-I;AIXC

2、md=/bin/sh,-c,/usr/sbin/lsdev-Ccprocessor|wc-l;HPUXCmd=/bin/sh,-c,echomap|/usr/sbin/cstm|grepCPU|wc-I;LinuxCmd=/bin/sh,-c,cat/proc/cpuinfo|grepprocess|wc-I;然后判断系统：os=System.getProperty().toLowerCase();根据不同的操作系统call不同的命令。*/importjava.io.IOException;importjava.io.InputStream;importjava.io.lnputStreamR
