//获取用户登录ip;String loginIp = request.getHeader("X-Forwarded-For");if (loginIp == null || loginIp.length() == 0 || "unknown".equalsIgnoreCase(loginIp)) { loginIp = request.getHeader("X-Real-IP");}if (loginIp == null || loginIp.length() == 0 || "unknown".equalsIgnoreCase(loginIp)) { loginIp = request.getHeader("Proxy-Client-IP");}if (loginIp == null || loginIp.length() == 0 || "unknown".equalsIgnoreCase(loginIp)) { loginIp = request.getHeader("WL-Proxy-Client-IP");}if (loginIp == null || loginIp.length() == 0 || "unknown".equalsIgnoreCase(loginIp)) { loginIp = request.getHeader("HTTP_CLIENT_IP");}if (loginIp == null || loginIp.length() == 0 || "unknown".equalsIgnoreCase(loginIp)) { loginIp = request.getRemoteAddr();} |

public class IpUtil { /** * 获取登录用户IP地址 * * @param request * @return */ public static 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(); } if (ip.equals("0:0:0:0:0:0:0:1")) { ip = "本地"; } return ip; }} |
