 }

 public static void main(String[] args) {
  GetMac getmac;
  getmac = new GetMac();
  String mac = "";
  mac = getmac.getMacAddressIP("192.168.0.100");// YOUR IP
  System.out.println(mac);
  mac = getmac.getMacAddressName("R61007");// YOUR HOST-NAME
  System.out.println(mac);
 }
}

获取ip地址的方法有二：
1.通过HttpServletRequest对象获取，可以在HttpServlet中获取，也可以在jsp中获取
a.在HttpServlet中获取
request.getRemoteAddr();
request.getRemoteHost();
b.在jsp中获取
在body中写下如下代码
<%
  String a = request.getRemoteAddr();
  String b = request.getRemoteHost();
  String c = java.net.InetAddress.getLocalHost().getHostAddress();
  %>

  <script type="text/javascript">
  var sys = ${it};
  b = "<%=a%>";
  </script>

2.不通过中间环节获取
String ip = java.net.InetAddress.getLocalHost().getHostAddress()；
