jsp:
1、首先需要获取客户机的ip地址
String sip = request.getHeader("x-forwarded-for");
if (sip == null || sip.length() == 0 || "unknown".equalsIgnoreCase(sip)) {
sip = request.getHeader("Proxy-Client-IP");
}
if (sip == null || sip.length() == 0 || "unknown".equalsIgnoreCase(sip)) {
sip = request.getHeader("WL-Proxy-Client-IP");
}
if (sip == null || sip.length() == 0 || "unknown".equalsIgnoreCase(sip)) {
sip = request.getRemoteAddr();
}
System.out.println(sip);
结果：
127.0.0.1
2、根据ip地址获得客户机的mac地址
在不同系统下的获取方式不同；
1）获得用户的操作系统：
String os = System.getProperty("os.name");
System.out.println(os);
结果：
Linux
2）根据所在的系统进行mac地址的获取
String macAddress = null;
if(os.equals("Windows"))
macAddress = getMacInWindows(ip).trim();
else if(os.equals("Linux"))
macAddress = getMacInLinux(ip).trim();
return macAddress;
其中在windows获取的方法：
public static String getMacInWindows(final String ip){
String result = "";
String[] cmd = {
"cmd",
"/c",
"ping " + ip
};
String[] another = {
"cmd",
"/c",
"arp -a"
};
String cmdResult = callCmd(cmd,another);
result = filterMacAddress(ip,cmdResult,"-");
return result;
}
在Linux获取的方法：
public static String getMacInLinux(final String ip){
String result = "";
String[] cmd = {
"/bin/sh",
"-c",
"ping " + ip + " -c 2 && arp -a"
};
String cmdResult = callCmd(cmd);
result = filterMacAddress(ip,cmdResult,":");
return result;
}
关键函数：
对结果进行分割获得mac地址；
/**
*
* @param ip 目标ip,一般在局域网内
* @param sourceString 命令处理的结果字符串
* @param macSeparator mac分隔符号
* @return mac地址，用上面的分隔符号表示
*/
public static String filterMacAddress(final String ip, final String sourceString,final String macSeparator) {
String result = "";
String regExp = "((([0-9,A-F,a-f]{1,2}" + macSeparator + "){1,5})[0-9,A-F,a-f]{1,2})";
Pattern pattern = Pattern.compile(regExp);
Matcher matcher = pattern.matcher(sourceString);
while(matcher.find()){
result = matcher.group(1);
if(sourceString.indexOf(ip) <= sourceString.lastIndexOf(matcher.group(1))) {
break; //如果有多个IP,只匹配本IP对应的Mac.
}
}
return result;
}
