Nginx反向代理+Tomcat+Springmvc获取用户访问ip

location / {
***********之前代码*******;
proxy_set_header host                $host;
proxy_set_header X-forwarded-for $proxy_add_x_forwarded_for;//设置代理服务器ip头，代码获取时的参数
proxy_set_header X-Real-IP  $remote_addr; //允许将发送到被代理服务器的请求头重新定义或者增加一些字段，显示真实的客户端的IP
}

//Springmvc方法中添加HttpServletRequest request参数
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 + "】");//自己代码里的日志打印
