NND,很多人都不装插件,没办法只能想另外的办法取mac。网上(http://wangxuliangboy.iyunv.com/blog/374298)找了一下代码回来改,只改了部分先存在这里
import java.io.IOException;
import java.net.DatagramPacket;
import java.net.DatagramSocket;
import java.net.InetAddress;
//import javax.servlet.http.HttpServletRequest;
/**
* 主机A向主机B发送“UDP-NetBIOS-NS”询问包,即向主机B的137端口,发Query包来询问主机B的NetBIOS Names信息。
* 其次,主机B接收到“UDP-NetBIOS-NS”询问包,假设主机B正确安装了NetBIOS服务........... 而且137端口开放,则主机B会向主机A发送一个“UDP-NetBIOS-NS”应答包,即发Answer包给主机A。
* 并利用UDP(NetBIOS Name Service)来快速获取远程主机MAC地址的方法

总结一下,现在一般有3中方法获取mac地址
1.通过ActiveX的方法
2.通过在客户端运行ipconfig这类dos或者shell命令
3.就是前面那种通过发送udp包,得到应答后分析取mac地址
1.通过ActiveX的方法,这个的问题就是这能跑在ie这类浏览器上,而且客户如果不允许插件运行,那也获取不了,太依赖客户行为。获取mac代码,我懒得整理了,直接从http://hi.baidu.com/fangqm/blog/item/d3f7c5eae1c1ecdbd539c93f.html这里cp过来,

2.通过在客户端运行ipconfig这类dos或者shell命令,这个的缺点就是如果在客户机子不允许/不能运行该类命令或者客户修改了该类命令(如ipconfig修改为ipcon)。另外还有可能在运行命令的时候发生阻塞,这个时候你就不知道什么时候能获取mac了。
获取方法还是懒得自己再写了,从http://blog.163.com/09zzy@126/blog/static/71197665201001504753750/拷贝过来

3.就是前面那种通过发送udp包,得到应答后分析取mac地址。缺点,首先你要获取准确的客户ip,并且客户机开发了netbios服务和137端口。
