spring-native | Spring Native is now superseded by Spring Boot 3 official | Application Framework library

I have a simple application built on top of org.springframework.boot:spring-boot-starter-parent version 2.5.4-SNAPSHOT and some derived dependencies:

• org.springframework.boot:spring-boot-starter-data-r2dbc
• org.springframework.boot:spring-boot-starter-webflux
• org.springframework.boot:spring-boot-starter-actuator
• io.r2dbc:r2dbc-postgresql

I use org.springframework.experimental:spring-native version 0.10.3 to enable Spring Native and build using the following plugin:

I am trying to build a native executable for an app that works with Quarkus and JavaFx. The only way I have managed to achieve this has been marking lots of javaFx classes as --initialize-at-run-time, but this causes that, when trying to start the app, it fails with the following message:

Question: Is there an option within spring or its embedded servlet container to open ports when spring is ready to handle traffic?

Situation: In the current setup i use a spring boot application running in google cloud run.

Circumstances:

• Cloud run does not support liveness/readyness probes, it considers an open port as "application ready".

• Cloud run sends request to the container although spring is not ready to handle requests.

• Spring start its servlet container, open its ports while still spinning up its beans.

Problem: Traffic to an unready application will result in a lot of http 429 status codes.

This affects:

• new deployments
• scaling capabilities of cloud run

My desire:

1. Configure spring/servlet container to delay opening ports when application is actually ready Delaying opening ports to the time the application is ready would ease much pain without interfering too much with the existing code base.

2. Any alternatives not causing too much pain?

3. Things i found and considered not viable

   • Using native-image is not an option as it is considered experimental and consumes more RAM at compile time than our deployment pipeline agents allow to allocate (max 8GB vs needed 13GB)

   • another answer i found: readiness check for google cloud run - how? which i don't see how it could satisfy my needs, since spring-boot startup time is still slow. That's why my initial idea was to delay opening ports

I did not have time to test the following, but one thing i stumbled upon is

• a blogpost about using multiple processes within a container. Though it is against the recommendation of containers principles, it seems viable for the time until cloud run supports probes of any type.

I'm tryying to use GraalVM native-image to compile a spring-boot project to build an .exe file.

my pom.xml :

I'm trying to build native images for spring-boot apps in a maven multi-module project.

As soon as I decorate a @Controller method with @PreAuthorize, native image generation fail with the message below.

Following spring-native samples, I tryed both with (as done in security-method-class-proxies) and without (as done in security-method) @AotProxyHint on application class, but this made no difference.

The error:

I have been trying to replicate this aws function example to deploy a lambda with spring cloud function and graalvm.

The function works locally and starts up without a problem.

I have a project early created and when trying to run mvn clean package command, or any other mvn command to build my .jar, the spring AOT plugin is throwing the following error:

I was trying to create a CRUD app using spring boot and postgres ,alongwith spring native.But I couldn't find any proper documentation related to it apart from spring native documentation.

The part of how to integrate it with postgres,is what I am looking for.Thankyou

I want to download spring-native dependency from maven mirror as it is not in my third party mirror.I tried to do it by including maven mirror in my settings.xml file,but it doesn't work.
