Creating a new project Micronaut offers two options to create a new project: A web UI: As for Spring Initializr, it provides several features: Preview the project before you download itShare the configurationAn API I do like that you can check the impact that the added features have on the POM.

Gone are the times when developers' jobs ended with the release of the application. Nowadays, developers care more and more about the operational side of IT: perhaps they operate applications themselves, but more probably, their organization fosters increased collaboration between Dev and Ops. I started to become interested in the Ops side of software when I was still a consultant. When Spring Boot released the Actuator, I became excited.

In the last couple of years, I’ve been playing a bit with a generation of tools in the Java world, namely Micronaut, Quarkus and GraalVM. While I’m a Spring Boot fan since its beginning, I believe this quite an eye-opening opportunity. In this post, I’d like to see how easy, or how hard, it is to port a simple Spring Boot application to Micronaut. Setting up the context The JVM is an great piece of technology.
