Getting started with Spring Boot AOT + GraalVM Native Images

In this tutorial you will learn the what, why and how of building native images in Spring Boot with GraalVM. Ahead-of-Time (AoT) compilation is a prerequisite for building native images with GraalVM. You will learn where this makes sense and then you will build out 2 simple Spring Boot Applications and build a native image from them.

Amazing presentation! Thanks!

[@aldosilva6]

Very nice presentation Dan. I didn't know that I could customize the JVM.

[@orestis131]

Nice presentation! Thanks

[@TheTallMan67]

Exciting. Thanks Dan

[@AlexTilkin]

Good video. Thank you, Dan

[@rabah4306]

Hello Dan thanks for your videos they are awesome!!! I have a question, what is your opinion on Monorepo?

[@bartomiejdziadosz8616]

Hello Dan, any video about graalvm + aws lambda?

[@remsbd]

Thanks for your video ! but i have an issue, 'gu' tool was not found...

[@dd1.d]

I’m not sure if anyone else has encountered this issue. When I have circular dependencies and use the @Lazy annotation to resolve them, the resulting native image fails to run

[@gamires]

@DanVega It is possible to build a native image from Windows to put in a docker image?

[@DanVega]

I don't have any experience with this but you can check out the docs docs.spring.io/spring-boot/docs/current/reference/html/native-image.html#native-image.developing-your-first-application.native-build-tools.prerequisites.windows

[@gamires]

@@DanVega Here is the answer "2.2. Building a Native Image Using Buildpacks" I run your example just well. Thank your very much!

[@RahulSingh-cl3wm]

Can you please cover limitations also?

[@DanVega]

What limitations? I pointed out that there are tradeoffs, one being time to build the native image and the other being you need to tell the compiler about anything dynamic that you're doing.

[@RahulSingh-cl3wm]

@@DanVega in context with spring what all dynamic features we cannot use.

[@007arek]

Hi Dan, are you familiar with JavaFX? I believe JavaFX could be great for native images. Why do you use legacy annotation like ShellMethod?

[@mrkostya008]

Did you just get out of uni for thinking that

[@007arek]

@@mrkostya008 no, why do you think that?

[@terribleprogrammer]

I am facing issues with Kerberos based apps. We use gss native. For some unknown reasons Kerberos based calls are failing. 😢

[@DanVega]

Sorry to hear that... I don't have any experience with Kerberos but you could always open up an issue on GitHub

[@curio78]

why is the native image still so big? 6 mb for one line code to say hello.

[@praveens2272]

Does anyone using this in production with containerising the application.

[@AbdurRahmanAcademy]

Not in production but we tried locally and there are many dependencies which still not fully supported

[@andytael]

We do use it for production, actually a CLI :-)

[@DanVega]

Yes this is being used in production. You can switch to the native profile and build a container docs.spring.io/spring-boot/docs/current/reference/html/native-image.html

[@OmarSoftwareDev]

Tried not working for me, something related with VS studio. This is is not as straightforward it seems

[@andytael]

Why are you using the wrapper, this works just fine for me: mvn clean -Pnative native:compile

[@DanVega]

Not everyone has maven installed locally so thats why I use the mvn wrapper in demos

[@mwigojonathanmark1683]

Spring Security breaks the native image execution
