java获取nginx反向代理的客户端真实ip(非服务器ip)

在使用nginx方向代理后

Remote Address代表的就是服务器的ip地址，而不是客户端的ip地址了，想要获取真实ip,就需要在nginx里面配置

worker_processes  1;
 
events {
    worker_connections  1024;
}
 
 
http {
    include       mime.types;
    default_type  application/octet-stream;
    log_format main '$remote_addr - $http_x_forwarded_for - $http_x_real_ip';
    access_log  logs/access.log  main;
 
    sendfile        on;
 
    keepalive_timeout  65;
     
    upstream tomcat_server_pool{
 
        #server 172.17.0.14:3000 weight=10;
    #server 172.17.0.14:3001 weight=10;
        server 127.0.0.1:1001 weight=10;
 
    }
 
 
    server {
        listen       80;
        server_name  localhost;
 
        location / {
         
            proxy_pass http://tomcat_server_pool;
  
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header Host $http_host;
            root   html;
            index  index.html index.htm;
        }
 
 
    }
 
 
 
}

　　其中X-Real-IP和X-Forwarded-For都是客户端真实地址

当nginx配置好的后，接下来需要在java中进行获取

public void login(HttpServletRequest request, Model model) {
       String remoteHost = request.getRemoteHost();
       String clientIp = request.getHeader("x-forwarded-for");
       log.info("clientIp:{}",clientIp);
       String proxyClientIP = request.getHeader("Proxy-Client-IP");
       log.info("proxyClientIP:{}",proxyClientIP);
 
       String xRealIP = request.getHeader("X-Real-IP");
       log.info("xRealIP:{}",xRealIP);
 
       String host = request.getHeader("Host");
       log.info("host:{}",host);
 
       String remoteAddr = request.getRemoteAddr();
       log.info("remoteAddr:{}",remoteAddr);
 
 
       model.addAttribute("year", TimeUtils.getYear());
       queryIp.judgeIp(model, remoteHost, request.getLocalAddr());
   }

　　结果

nginx相关命令

/usr/local/webserver/nginx/sbin/nginx -s reload            # 重新载入配置文件
/usr/local/webserver/nginx/sbin/nginx -s reopen            # 重启 Nginx
/usr/local/webserver/nginx/sbin/nginx -s stop              # 停止 Nginx
