I really prefer Bootique as an alternative to Spring Boot: https://bootique.io/ Simpler, smarter, very easy to customize.

For higher loads I pick Vert.x.

Other than that, it's almost always 3 J's: Jetty, Jersey, Jackson.

Can I ask why you prefer Jersey over say the REST stuff you can do with Spring, and Jackson over GSON or Jettison?
