Nginx反向代理+Tomcat+Springmvc獲取用戶訪問ip

Nginx+Tomcat+Springmvc獲取用戶訪問ip

1.Nginx反向代理 
修改Nginx配置文件

location / {
        ***********之前代碼*******;
        proxy_set_header host                $host;
        proxy_set_header X-forwarded-for $proxy_add_x_forwarded_for;//設置代理服務器ip頭，代碼獲取時的參數
        proxy_set_header X-Real-IP  $remote_addr; //允許將發送到被代理服務器的請求頭重新定義或者增加一些字段，顯示真實的客戶端的IP
}

2.Springmvc代碼中添加方法

            //Springmvc方法中添加HttpServletRequest request參數
            String ip = request.getHeader("x-forwarded-for");
            if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
                ip = request.getHeader("Proxy-Client-IP");
            }
            if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
                ip = request.getHeader("WL-Proxy-Client-IP");
            }
            if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
                ip = request.getRemoteAddr();
            }
            Utils.log.info("【ip:" + ip + "】");//自己代碼里的日志打印
