The best Java microframeworks to learn now
"import io.javalin.Javalin; public class App { public static void main(String[] args) { var app = Javalin.create() .get("/", ctx -> ctx.result("Hello World")) .start(7070); } } Notice the fluent method changing and clean code, allowing us to describe the server definition and endpoints together. Javalin avoids bloat and any unnecessary dependency syntax. If you are looking for a minimalist framework to get the job done, Javalin may be the framework for you."
"Micronaut is a great option when startup time is paramount, and/or if you want a multi-language, full-stack framework for building microservices and serverless apps. It gives you an AOT compiler that provides performance and dependency injection without reflection. It can run in the JVM or compile down to native images with GraalVM. The way the Micronaut IoC (inversion of control) container works means all dependencies are resolved during compilation."
Javalin provides a minimalist, low-dependency approach for defining servers and endpoints with concise, fluent code and lightweight configuration. Javalin's API enables quick setup of HTTP handlers with minimal boilerplate, focusing on readability and avoiding unnecessary dependencies. Micronaut prioritizes extremely fast startup and low-memory dependency injection through an ahead-of-time (AOT) compiler and compile-time IoC resolution. Micronaut supports Java, Groovy, and Kotlin and can target the JVM or native images via GraalVM. Micronaut includes cloud-oriented features such as service discovery, tracing, distributed configuration, datastore connectors, and OpenAPI support while keeping endpoint code simple and readable.
