Apart from the application.properties, my service also needs to load sites properties. To be more precise, in the sites folder I have nested site.properties files, those are files that I need to load when the application is starting and put them to the list (List sites)

Using spring boot mechanisms like @PropertySource, is it possible to search for the files with the same name, map each of them to the Site property class and put to the list?

I'm not sure about

put to the list

but If I understand correctly, you can

search for the files with the same name, map each of them to the Site
property class

by using prefix in properties file as sample below :
