I just wanted to update the alternate solution I found for this problem, for completeness.
Spring Security Filter chain was not working for Weblogic, where as same was working in Tomcat, even for Weblogic version 12.2.1.4.
I had followed this example, and implemented Okta filter as spring boot version was not working in Weblogic 12.2.1.4.
Thanks to @Toerktumlare, I have implemented logging with logback-spring.xml
