Proof-of-concept Quarkus Rest DB and H2 example application

Example application using Quarkus with similar functionality as the Spring example of my book "Getting Started with Java on Raspberry Pi", see this GitHub project which is part all the examples of the book.

This project uses Quarkus, the Supersonic Subatomic Java Framework. If you want to learn more about Quarkus, please visit its website: https://quarkus.io/ .

Empty project

The initial code was created with

mvn io.quarkus:quarkus-maven-plugin:1.6.0.Final:create     
    -DprojectGroupId=be.webtechie.javaquarkusrestdb     
    -DprojectArtifactId=javaquarkusrestdb    
    -DclassName="be.webtechie.javaquarkusrestdb.resource.GreetingResource"

Running the application in dev mode

You can run your application in dev mode that enables live coding using:

./mvnw quarkus:dev

Packaging and running the application

The application can be packaged using ./mvnw package. It produces the getting-started-1.0-SNAPSHOT-runner.jar file in the /target directory. Be aware that it’s not an über-jar as the dependencies are copied into the target/lib directory.

The application is now runnable using java -jar target/getting-started-1.0-SNAPSHOT-runner.jar.

Creating a native executable

You can create a native executable using: ./mvnw package -Pnative.

Or, if you don't have GraalVM installed, you can run the native executable build in a container using: ./mvnw package -Pnative -Dquarkus.native.container-build=true.

You can then execute your native executable with: ./target/getting-started-1.0-SNAPSHOT-runner

If you want to learn more about building native executables, please consult https://quarkus.io/guides/building-native-image.
