有哪些不错的基于 JVM 的 Web 服务器库？

Question

I currently have a Kotlin app that I'd like to expose with a REST API server. I'm finding really hard to decide for a web framework to build around it.

My background is Node.JS with express and I'm trying to find something at least similar to it at the level of middleware and modularity. But since I just started learning Java recently the getting started part is the major entry-barrier.

What striked me as appropriate was Spark but I can't find a way to separate my routes between different files and have local-per-file middleware.

I considered Play but it seemed that it needed a very big level of setup for a new app, even more if it's an existing one.

While my app ain't that big I plan on evolving it so I need something that can scale appropriately. So I'm asking what options do I have? I'm really looking forward on working with Spark if I can tackle those 2 issues previously mentioned, any help about them is appreciated.

Try one of these:

• https://projects.spring.io/spring-boot/ (lots of libs, quiet complicated, but powerful)
• http://restx.io/
• Jersey2
• Resteasy
