java获取ip的工具类

直接上代码

package com.loit.park.common.utils;import org.slf4j.Logger;
import org.slf4j.LoggerFactory;import javax.servlet.http.HttpServletRequest;
import java.net.InetAddress;
import java.net.UnknownHostException;/*** @author hanjinqun* @date 2023/6/27*/
public class IpUtil {public static Logger LOGGER = LoggerFactory.getLogger(IpUtil.class);/*** @Description: 获取当前网络ip* @Param: [request]* @return: java.lang.String* @Author: hanjinqun* @Date: 2023/6/27*/public static String getIpAddr(HttpServletRequest request) {String ipAddress = request.getHeader("x-forwarded-for");if (ipAddress == null || ipAddress.length() == 0 || "unknown".equalsIgnoreCase(ipAddress)) {ipAddress = request.getHeader("Proxy-Client-IP");}if (ipAddress == null || ipAddress.length() == 0 || "unknown".equalsIgnoreCase(ipAddress)) {ipAddress = request.getHeader("WL-Proxy-Client-IP");}if (ipAddress == null || ipAddress.length() == 0 || "unknown".equalsIgnoreCase(ipAddress)) {ipAddress = request.getRemoteAddr();if (ipAddress.equals("127.0.0.1") || ipAddress.equals("0:0:0:0:0:0:0:1")) {//根据网卡取本机配置的IPInetAddress inet = null;try {inet = InetAddress.getLocalHost();} catch (UnknownHostException e) {e.printStackTrace();}ipAddress = inet.getHostAddress();}}//对于通过多个代理的情况，第一个IP为客户端真实IP,多个IP按照','分割if (ipAddress != null && ipAddress.length() > 15) { //"***.***.***.***".length() = 15if (ipAddress.indexOf(",") > 0) {ipAddress = ipAddress.substring(0, ipAddress.indexOf(","));}}return ipAddress;}
}
