GraalVM Native Image Example Application with Spring Boot 3

Spring Boot GraalVM Native Image Example Application

This is a followup of https://github.com/kuromogeko/graal-consent. For an explanation of the application and its purpose please refer to the original repository.

This Readme will list differences to the original App.

Dependencies

Unlike the original this depends on Spring Boot 3 and GraalVM CE with a minimum Version of 22.3.

Native Image compile

Is now achieved by running

mvn -Pnative native:compile

A Docker build could be run using Paketobuilder but is untested.

mvn -Pnative spring-boot:build-image

Reflection Config

Reflect Config gains a new Entry apparently due to a change in how Spring AOT interacts with Jackson.

{
    "name": "de.examples.graal.consent.consent.domain.actors.user.UserCharacteristic",
    "allPublicFields": true,
    "allDeclaredFields": true,
    "allDeclaredConstructors": true,
    "allPublicConstructors": true,
    "allDeclaredMethods": true,
    "allPublicMethods": true
  }

Known Issues

Javascript in this project ist currently disabled (ConsentEventListener not registered as component, language:js removed in call to native image). This is due to Spring Boot now requiring the Graal native Compiler Feature ParseOnce. Truffle Languages however require ParseOnce to be disabled to work. The Issue is also known to the GraalVM Development team and will be fixed with a later release.
