Perhaps kotlin doesn't make much sense wrt dropwizard -- it might make more sense to just stick with java for dw, and use something different if one wants something higher level?
Anyway, some related links I've come across googling a bit:
clojure+dropwizard (example, with leiningen):
https://github.com/stevensurgnier/dropwizard-clojure
Experimental (old) repo for dropwizard+kotlin:
https://github.com/arteam/kotlin-dropwizard
Combining kotlin and guice:
My plan is to add more to it and eventually cover all the features of Dropwizard.
In order to make this reply have a bit more substance than just a link, the idea of using Guice is pretty neat if you think about unit testing your code. Instead of letting the container (jetty) instantiate the webapp, let Guice do it.
This means that you can run tests without firing up the container. In other words, no need to test through the http layer by making requests to a web server. Additionally, by removing a rather large layer of code, tests run much faster.
Instead, now you write your tests directly against your Resource class methods (yea static compiled code!). Building up routes, query strings and POST requests is a thing of the past. No need to mock your data layer either since you can test against a real in-memory database.
Here is an example of what I'm talking about: https://github.com/gwizard/gwizard-example/blob/master/src/t...
