java获取手机IP地址不准确解决

修改nginx.conf配置，增加配置，代表真实获取header为真实ip
proxy_set_header X-real-ip $remote_addr;
如下：

然后调用获取IP工具类

package com.shijie.box.util;
import javax.servlet.http.HttpServletRequest;
public class NewUtils {

    /**
     * 获取请求ip
     * @param request
     * @return
     */
    public static String getRealIp(HttpServletRequest request) {
        String ip = request.getHeader("x-forwarded-for");
        if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
            //Proxy-Client-IP：apache 服务代理
            ip = request.getHeader("Proxy-Client-IP");
        }

        if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
            //WL-Proxy-Client-IP：weblogic 服务代理
            ip = request.getHeader("WL-Proxy-Client-IP");
        }

        if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
            //HTTP_CLIENT_IP：有些代理服务器
            ip = request.getHeader("HTTP_CLIENT_IP");
        }

        if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
            //X-Real-IP：nginx服务代理
            ip = request.getHeader("X-Real-IP");
        }

        //有些网络通过多层代理，那么获取到的ip就会有多个，一般都是通过逗号（,）分割开来，并且第一个ip为客户端的真实IP
        if (ip != null && ip.length() != 0) {
            ip = ip.split(",")[0];
        }


        if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
            ip = request.getRemoteAddr();
        }

        return ip;
    }
}
