failed to load api definition after spring boot 3.4.0-M2

[rajadilipkolli]

Describe the bug

I am using spring-boot-starter-webflux in conjunction with springdoc-openapi-starter-webflux-ui 2.6.0 version , it was working with spring boot 3.3.3 version.

After upgrading the same to 3.4.0-M2 , I am getting below error on UI loading, skeleton is rendered but apis are not due to below error.

Failed to fetch /v3/api-docs

Expected behavior

UI loaded with APIs

Screenshots

Additional context

Stacktrace :

I can confirm this issue, it happens to me when I have a custom @RestControllerAdvice bean in the project. When I commented it out, everything works.

Problematic code is in org.springdoc.core.service.GenericResponseService#getGenericMapResponse:

List<ControllerAdviceInfo> controllerAdviceInfosNotInThisBean = controllerAdviceInfos.stream()
    .filter(controllerAdviceInfo ->
        new ControllerAdviceBean(controllerAdviceInfo.getControllerAdvice()).isApplicableToBeanType(beanType))
    .filter(controllerAdviceInfo -> !beanType.equals(controllerAdviceInfo.getControllerAdvice().getClass()))
    .toList();

seems like the ControllerAdviceBean constructor has changed in SB 3.4

If it helps, here is a stacktrace even without a custom @RestControllerAdvice:

ControllerAdviceBean is defined in spring-framework and this issue will affect EVERYONE upgrading SF to 6.2+ which is already on RC now.

Can we get some movement on this issue please.

@efemoney

Thank you for raising this concern.
Please remember to should follow its contributing guidelines and code of conduct.

spring-boot 3.4 is not yet GA.

A good next step would be to propose a pull request (PR) to address the problem.
This will help move things forward faster by providing a concrete solution that can be reviewed and tested by the community.
If you haven't already, feel free to propose a PR so we can assess the fix and ensure it's implemented smoothly in time for the official release.

Otherwise, the community will address it when i or someone has the bandwidth to take a closer look.

[efemoney]

You're right, sorry. Spring 6.2 is in RC. I will push a PR once it's released. Thanks!

Hello...Any further updates, with which springboot version it is going to be fixed ? I am at 3.4.1 and it's not working.

[rajadilipkolli]

Hi @gauravsg24 , you should use 2.8.3 version with sb 3.4.1
