下面这个方法是获取客户端请求地址
public String getClientIp(HttpServletRequest request) {
String ip = request.getHeader("x-forwarded-for"
);
if (ip ==
null || ip.length() == 0 || "unknown"
.equalsIgnoreCase(ip)) {
ip = request.getHeader("Proxy-Client-IP"
);
}
if (ip ==
null || ip.length() == 0 || "unknown"
.equalsIgnoreCase(ip)) {
ip = request.getHeader("WL-Proxy-Client-IP"
);
}
if (ip ==
null || ip.length() == 0 || "unknown"
.equalsIgnoreCase(ip)) {
ip =
request.getRemoteAddr();
}
if(ip.trim().contains(","
)){
String [] ips=ip.split(","
);
ip=ips[0
];
}
return ip;
}
