Hello Team,
I recently tried reading contents from application.yml file in a Spring Boot project (Version 2.3.4).
Initially, all the properties from yml file were getting read as null.
After cleaning and rebuilding project several times, I could read all the properties except the List of user defined class object (List<LogComponents> in below class) which is still getting read as null.
I tried all the possible solutions but nothing worked for me.
Could you please check and help me in understanding what I have missed in below code because of which the value for List<LogComponent> logComponents is still getting read as null from yml file?
Thanking you in anticipation!
