如果使用代理的话，用户的浏览器并没有和你的服务器进行连接，所以你是无法得知用户的真正地址的。

获得客户端真实IP地址的参考方法一：
public String getRemortIP(HttpServletRequest request) {
if (request.getHeader("x-forwarded-for") == null) {
return request.getRemoteAddr();
}
return request.getHeader("x-forwarded-for");
}

获得客户端真实IP地址的参考方法二：

public String getIpAddr(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();
}
return ip;
}

String logIp = request.getHeader("X-Forwarded-For");

if(logIp == null || logIp.length() == 0) {
logIp=request.getHeader("WL-Proxy-Client-IP");
}
if(logIp == null || logIp.length() == 0) {
logIp=request.getRemoteAddr();
}

out.print(logIp);
