第一步:在nginx.conf中配置反向代理时把真实IP带上,例如:
server {
listen 80;
server_name boyan.com;
location ~ ^/(WEB-INF)/ {
deny all;
}
location / {
proxy_pass http://localhost:8888;
proxy_set_header X-Real-IP $remote_addr;
}
}
第二步:应用程序中用 String ip = request.getHeader("X-Real-IP");替代String ip = request.getRemoteAddr();即可
