[FIXED] Handle c-dns and s-dns values in access log

Issue

I'm using Spring boot 2.1.10 and I want to customize embedded tomcat access logs. I'm using this pattern in the application.yml file;

      pattern: "[ACCESS] %{id}i   %{x-forwarded-for}i %{client-ip}i   %{server-ip}i  %{dd.MM.yyyy}t  %{HH:mm:ss}t    %U %s %s  %m %T  %B  %{user-agent}i"

The problem is, I cannot get C-DNS and S-DNS values. When I look at the tomcat documentation in this url, usage listed like this;

The following format tokens are supported:

• C-DNS - Remote hostname (or IP address if enableLookups for the connector is false)
• S-DNS - Local hostname

I tried it like this : %{c-dns}i or %{c-dns} or {c-dns} or c-dns nothing worked.

Do you have any suggestions?

Solution

I found the proper way with writing my own configuration class. Guide : Baeldung
