Spring MVC如何获取客户端IP地址呢?

Spring MVC获取客户端IP地址的实现思路:
     1.使用Autowired将HttpServletRequest注入到指定的变量上
	 2.编写相应的方法即可获取客户端IP地址

WebUtils.java

package com.java265.web;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import javax.servlet.http.HttpServletRequest;
 
@Component
public class WebUtils {
    private HttpServletRequest request;
 
    @Autowired
    public void setRequest(HttpServletRequest request) {
        this.request = request;
    }
 
    private static String getClientIp() {
        String remoteAddr = "";
        if (request != null) {
            remoteAddr = request.getHeader("X-FORWARDED-FOR");
            if (remoteAddr == null || "".equals(remoteAddr)) {
                remoteAddr = request.getRemoteAddr();
            }
        }
        return remoteAddr;
    }
}
