本文介绍了一种在Java服务端获取客户端真实IP地址的方法。通过检查不同的HTTP头部信息，该方法能够适应多种网络环境，确保即使在使用代理服务器的情况下也能准确获取到客户端的实际IP。

在服务端java代码中获取客户端访问IP地址代码：

public String getRequestIp(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.getHeader("HTTP_CLIENT_IP");
	}
	if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
		ip = request.getHeader("HTTP_X_FORWARDED_FOR");
	}
	if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
		ip = request.getRemoteAddr();
	}
	return ip;
}
