nginx后的tomcat获取真实用户ip

目前大部分获取ip的方式：beat.getRequest().getRemoteAddr()
但是，如果通过nginx反向代理的话，就获取不到真实ip，是获取的nginx的ip

需要：添加 proxy_set_header X-Real-IP $remote_addr;

   server {        listen       80;        server_name  price.kuche.com;        location / {            root   html;      proxy_set_header  X-Real-IP  $remote_addr;            proxy_pass http://price.kuche.com:8053;         }   }

添加一个表头声明

然后这样取

public static String getRemoteAddrIp(HttpServletRequest request) {String ipFromNginx = getHeader(request, "X-Real-IP");System.out.println("ipFromNginx:" + ipFromNginx);System.out.println("getRemoteAddr:" + request.getRemoteAddr());return StringUtil.isEmpty(ipFromNginx) ? request.getRemoteAddr() : ipFromNginx;}private static String getHeader(HttpServletRequest request, String headName) {String value = request.getHeader(headName);return !StringUtils.isBlank(value) && !"unknown".equalsIgnoreCase(value) ? value : "";}
