spring-tips/spring-boot-3-aot

Hi, Spring fans! In this installment we briefly look at some of the new support for building native applications in Spring Framework 6 and Spring Boot 3

spring-boot-3-aot's Issues

images in README.adoc are broken

While yesterday all the image in README.adoc were show just perfectly, today they are not, why is that ?
I refer to for instance :
image::{root}/images/reachability-metadata.png[]
which now show like this:

Binary file size question

Why is the compiled binary larger than the jar package ?

Windows issue?

First of all, thanks for these examples - they have been really helpful.

I am experiencing an error when running the compiled .exe on Windows, linked to the scopes example.

Is there a hint I might be missing?
Thanks.

Request: Full DataDog tracing guide

Hi @joshlong

Hope it's ok to put this request here.

I'd really, really appreciate if you could add something to this guide on how to correctly setup monitoring and distributed tracing such that it works on an AOT build of Spring Boot 3 and can be sent to DataDog.

I've had nothing but bother trying to get this to work, and there are no useful guides or documentation that conclusively show how to do this. (some are too old, some reference different libraries, some use zipkin (which I don't want))
Thanks

XML Configuration is not picked in native image.

I created a simple spring boot web application which uses applicationContext.xml to define a bean. The application runs fine on jvm and serves a simple hello user message on rest call. But when I convert this application to spring boot native image it fails to run because it cannot find this bean defined in the applicationContext.xml. I used @ImportResource("applicationContext.xml") to read the context file. The xml is placed in src/main/resources folder. It seems that spring native image cannot read the xml file and completely ignores it.
I have build the image using native build tools with GraalVM distribution.
Can you please help.
