This Petclinic is a Micronaut application which I forked from Spring PetClinic and tried to migrate from Spring to Micronaut to know how Micronaut works. I respect Spring so much, and I think I should replace Spring logos with Micronaut logos to avoid confusion.

git clone https://github.com/bufferings/micronaut-petclinic.git
cd micronaut-petclinic

This Petclinic uses PostgreSQL. You could start PostgreSQL with docker:

docker-compose up db

./mvnw compile exec:exec

You can then access petclinic here: https://localhost:8080/

./mvnw package
java -jar target/*.jar

This PetClinic supports GraalVM native image build.

./mvnw package && docker build -t micronaut-petclinic .

I usually have ☕ (around 10 mins on my laptop) to wait for the build finishes.

Use Docker compose to start the application:

docker-compose up -d

It starts in 300-400ms.

From GraalVM 19.0.0, it fails to build native-image because of this issue: oracle/graal#1295

It works if I build GraalVM from master branch and use it. So for now, I prepared a Docker image with the build: https://hub.docker.com/r/bufferings/build-graalvm-docker
