HttpServletRequest获取远程客户端IP(考虑代理)以及java获取本机IP地址(去除虚拟机、蓝牙等)

protected String getRemoteIP() {
		String ip = null;

		// X-Forwarded-For：Squid 服务代理
		String ipAddresses = request.getHeader("X-Forwarded-For");
		if (ipAddresses == null || ipAddresses.length() == 0 || "unknown".equalsIgnoreCase(ipAddresses)) {
			// Proxy-Client-IP：apache 服务代理
			ipAddresses = request.getHeader("Proxy-Client-IP");
		}
		if (ipAddresses == null || ipAddresses.length() == 0 || "unknown".equalsIgnoreCase(ipAddresses)) {
			// WL-Proxy-Client-IP：weblogic 服务代理
			ipAddresses = request.getHeader("WL-Proxy-Client-IP");
		}
		if (ipAddresses == null || ipAddresses.length() == 0 || "unknown".equalsIgnoreCase(ipAddresses)) {
			// HTTP_CLIENT_IP：有些代理服务器
			ipAddresses = request.getHeader("HTTP_CLIENT_IP");
		}
		if (ipAddresses == null || ipAddresses.length() == 0 || "unknown".equalsIgnoreCase(ipAddresses)) {
			// X-Real-IP：nginx服务代理
			ipAddresses = request.getHeader("X-Real-IP");
		}

		// 有些网络通过多层代理，那么获取到的ip就会有多个，一般都是通过逗号（,）分割开来，并且第一个ip为客户端的真实IP
		if (ipAddresses != null && ipAddresses.length() != 0) {
			ip = ipAddresses.split(",")[0];
		}

		// 还是不能获取到，最后再通过request.getRemoteAddr();获取
		if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ipAddresses)) {
			ip = request.getRemoteAddr();
		}
		
		//如果获取到的是127.0.0.1或0:0:0:0:0:0:0:1，就获取本地ip
		try {
			ip = getHostIP();
		} catch (SocketException e) {
			LogUtil.error("获取本机IP异常！", e);
		}

	}
