Spring Boot is pretty good actually. It doesn’t match some of Django’s features, but if I were to use JVM now, either Spring Boot or a standard Clojure stack with Ring (coupled with Honeywell) would be good enough. (Of course finding Clojure devs is harder, I have spent a lot of time evangelizing it in my country with little success.) I have used both last year in production without issues.

Still, Django and Rails makes many things a breeze.
