  3. Dropwizard

    A damn simple library for building production-ready RESTful web services.

  4. Jooby

    The modular web framework for Java and Kotlin

    One of the good things about it is that using asynchrony is optional. If you don't have to call out anywhere to build the response, processing can all stay in the handler's calling thread. If you do, you can return a future and have the library handle the async for you.

    One downside is that it is based on Jetty which isn't considered the most performant backend. A lib with a similar API but based on Netty is Jooby [1] which scores well in the Techempower benchmarks.

  5. Micronaut

    Micronaut Application Framework

    Micronaut has a share of the space too.

    However, you’re right that Spring Boot has the lions share of the Java ecosystem.

  6. manifold

    Manifold is a Java compiler plugin, its features include Metaprogramming, Properties, Extension Methods, Operator Overloading, Templates, a Preprocessor, and more.

    > I am glad to see a project that provides a robust and elegant API for building rest services in Java.

    Alternatives for _consuming_ REST services is perhaps an equally interesting proposition, particularly since there are potentially potentially many consumers per service e.g., the manifold JSON project[1].

    Other areas where Springboot feels overbearing include JPA/ORM support. In my view this is its greatest weakness, but like the "no one ever got fired for buying IBM" cliche, the same can be said today about Springboot.
