Your comment misses alot of nuances about Clojure. Most Clojure devs I know were already senior devs in one or more languages, and were very capable of dealing with any missing "out of the box" functionality. Besides, by sitting on top of the JVM you have access to alot of mature libraries, and it's extremely easy to do a wrapper in clojure. What the spring & other frameworks have as an advantage is a predefined set of opinionated choices about logging, error handling, validation and so on that would give you a couple of weeks advantage at top. What they don't have is an expressive language as clojure.
