i’m not sure i understand the question
if you mean, can you use those 2 dependencies at the same time, sure you can
if you mean, can i have some endpoints handled by spring webmvc and some handled by ktor, nope
you’ll need to start both web servers
so you’ll need to choose a different port for each of them
unless there’s some spring boot ktor integration
they won’t work together but side-by-side
