Java中获取客户端真实IP地址

获取IP地址在做登录日志的时候会用到，Java中获取客户端真实IP地址代码如下：

import org.apache.commons.lang3.StringUtils; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import javax.servlet.http.HttpServletRequest; /** * 获取IP地址 * * @Author Lizhou */ public class IPUtils { private static Logger logger = LoggerFactory.getLogger(IPUtils.class); /** * 获取客户端真实ip地址 * * @param request * @return */ public static String getIpAddress(HttpServletRequest request) { String ip = null; try { ip = request.getHeader("x-forwarded-for"); if (StringUtils.isEmpty(ip) || "unknown".equalsIgnoreCase(ip)) { ip = request.getHeader("Proxy-Client-IP"); } if (StringUtils.isEmpty(ip) || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) { ip = request.getHeader("WL-Proxy-Client-IP"); } if (StringUtils.isEmpty(ip) || "unknown".equalsIgnoreCase(ip)) { ip = request.getHeader("HTTP_CLIENT_IP"); } if (StringUtils.isEmpty(ip) || "unknown".equalsIgnoreCase(ip)) { ip = request.getHeader("HTTP_X_FORWARDED_FOR"); } if (StringUtils.isEmpty(ip) || "unknown".equalsIgnoreCase(ip)) { ip = request.getRemoteAddr(); } } catch (Exception e) { logger.error("IPUtils ERROR ", e); } return ip; } } import or
