工具类：

import javax.servlet.http.HttpServletRequest;
    import java.net.InetAddress;
    import java.net.UnknownHostException;

    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;
    }
