Spring Boot with embedded Tomcat behind Apache proxy

Question

We have a Spring Boot (Spring MVC) app with embedded Tomcat on a dedicated appserver behind an Apache SSL proxy.

The SSL port on the proxy server is 4433, forwarding

Answer 1

I had exactly the same case using haproxy as load balancer with the below configuration, which worled for me. The only thing is the client IP is in request.getRemoteAddr() and not in "X-Forwarded-For" header

frontend www
  bind *:80
  bind *:443 ssl crt crt_path
  redirect scheme https if !{ ssl_fc }
  mode http
  default_backend servers

backend servers
  mode http
  balance roundrobin
  option forwardfor
  server S1 host1:port1 check
  server S2 host2:port2 check
  http-request set-header X-Forwarded-Port %[dst_port]
  http-request add-header X-Forwarded-Proto https if { ssl_fc }

In application.properties:

 server.use-forward-headers=true
