工具类：
import javax.servlet.http.HttpServletRequest; import java.net.InetAddress; import java.net.UnknownHostException; /** * @Author : JCccc * @CreateTime : 2018-11-23 * @Description : * @Point: Keep a good mood **/ public class IpUtil { public static String getIpAddr(HttpServletRequest request) { String ipAddress = null; try { 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")) { // 根据网卡取本机配置的IP InetAddress 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() // = 15 if (ipAddress.indexOf(",") > 0) { ipAddress = ipAddress.substring(0, ipAddress.indexOf(",")); } } } catch (Exception e) { ipAddress=""; } // ipAddress = this.getRequest().getRemoteAddr(); return ipAddress; } }
方法调用：
(当接口 /test 被调用，request就能自动获取出来，然后调用工具类方法进行解析获取了。)
@RequestMapping(value = "/test", method = RequestMethod.GET) public String test(HttpServletRequest request){ //获取IP地址 String ipAddress =IpUtil.getIpAddr(request); return ipAddress; }
