Parameter 4 of method swaggerWelcome in org.springdoc.webflux.ui.SwaggerConfig required a bean of type 'org.springframework.web.reactive.result.method.RequestMappingInfoHandlerMapping' that could not be found.

Hello,

I have a Springboot 2.5.0 app with springdoc-openapi-webflux-ui 1.5.4, and everything was very fine, very happy.

Upgraded to 1.5.5, still with Springboot 2.5.0.

From there, seeing this issue:

APPLICATION FAILED TO START

Description:

Parameter 4 of method swaggerWelcome in org.springdoc.webflux.ui.SwaggerConfig required a bean of type 'org.springframework.web.reactive.result.method.RequestMappingInfoHandlerMapping' that could not be found.

Action:

Consider defining a bean of type 'org.springframework.web.reactive.result.method.RequestMappingInfoHandlerMapping' in your configuration.

Could you please help?
Thank you

@patpatpat123,

v1.5.5 does not yet support 2.5.0 which not yet GA.
It is validated against 2.4.3 or earlier versions of spring-boot.

You have the last version supported of spring-boot, using the parent pom.xml

This ticket will be now closed. And it will be treated as part of the support of the next spring-boot 2.5.0 G.A.

If you are having a minimal reproducible sample, don't hesitate to add it.

I just want to say thanks to @patpatpat123 -- I ran into the same issue (or at least the same symptom) updating to springdoc-openapi-webflux-ui 1.5.5 (from 1.3.9) with Spring Boot 2.4.3. Saw this posting, rolled back to 1.5.4 and (with only that one character change) now the app launches fine.

@bnasslahsen It would take a fair amount of effort to strip this down to a minimal example - if important, reply and I'll make the time this week. But it is odd no one else has reported it in two months.

Hi @larrywest,

The current version 1.5.8 supports vspring-boot 2.4.5 without any issue.

Would be happy to help if you provide a minimal reproducible sample.
You have a lot of samples on the project tests.

Hello @bnasslahsen,

2.5.0 is now GA, the issue still persist.
Can you please help check?

Thank you

@patpatpat123,

The support of 2.5.0 is done. There is nothing related to RequestMappingInfoHandlerMapping.
As suggested earlier, you should provide a minimal reproducible sample, so we can reproduce your issue.

You have a lot of samples on the project tests.

[patpatpat123]

Is it possible to publish the support to Maven Central (the support or 2.5.0) please?

When I use 1.5.5, 1.5.6, 1.5.7 and 1.5.8, the issue is 100% reproducible.

When I stick with 1.5.4, no issue.

I am trying to find out what is the change between 1.5.4 and 1.5.5 causing this issue, as well as I parallel, would like to test the new support for 2.5.0 please

[bnasslahsen]

I understand you can reproduce the issue. But we cannot!
Again, without without you providing a reproducible sample, we can do nothing about it.

All the demos are here, working fine.

Release v1.5.9, which will officially be supporting spring-boot 2.5.0 should be released later this weekend.

Note that, If you are not willing to provide a reproducible sample, i will lock this thread.
