GluonWithSpring

Demonstration of Gluon native image generation with springboot + JavaFX application.

Sample project inspired by https://github.com/guirak/GluonWithSpring/tree/master but demonstrate how to create a native image through graalvm for a JavaFX and Springboot application. The build is composed via maven of spring AOT + GluonFX.

See gluonFX at : https://docs.gluonhq.com/

This project has been tested on Windows to create a native image exe file.

For this, you have to install all the gluonFX specific versions as described in the link. Here are my configuration :

• Java 21 (from eclipse adoptium) on windows
• maven 3.8.8
• graalvm-svm-java17-windows-gluon-22.1.0.1-Final
• Microsoft VS Code 2022 with the C compiler build tools

How to build this project :

In a VS Code CLI (e.g. launched via : cmd /k "C:\VisualStudio\2022\Community\VC\Auxiliary\Build\vcvars64.bat"), build with maven : mvn clean install test with : launch.bat

Build the native executable : run spring AOT : mvn -Pnative spring-boot:process-aot

build native with gluonFX : mvn gluonfx:build

Run it : mvn gluonfx:nativerun

Or double clic on the executable in target\gluonfx\x86_64-windows\GluonWithSpring.exe

Performance :

On my PC which is quite limited in resources :

• the standard java and jar launch uses 185 Mb of RAM and has a startup time of 2.4s

• the native executable uses 86 Mb of RAM and has a startup time of 0.06s :)
