Hi all, I can't seem to wrap my head around getting Springdoc to work with my Kotlin Spring Boot app that uses the function DSL to register beans and routes. (There are no Bean, Service, etc annotations) Does anyone have an example on how to get this to work? I have tried putting the RouterOperation annotation on the handler methods, but the swagger ui still comes up empty.

Are you bringing in the springdoc-openapi-kotlin dependency?

[Adam Crane]

yes, as well as the springdoc-openapi-security dependency

[Topher Lamey]

and springdoc-openapi-ui ?

[Topher Lamey]

or springdoc-openapi-webmvc-core if you don’t want swagger-ui

[Adam Crane]

yes, the springdoc-openapi-ui is added (3 packages altogether)

[Topher Lamey]

What does your RouterFunction with the @RouterOperation look like? I’m not super familiar with this, but here are a bunch of caveats: https://springdoc.org/#spring-webfluxwebmvc-fn-with-functional-endpoints

[Topher Lamey]

Like if it’s not a single route or not, is it using the beanClass and beanMethod, if using @Operation is the operationId set

[Topher Lamey]

Kind of odd that their example doesn’t use @RouterOperation: https://github.com/springdoc/springdoc-openapi-demos/tree/master/springdoc-openapi-spring-boot-2-webflux-functional

[Topher Lamey]

It looks it’s using GroupedOpenApi: https://github.com/springdoc/springdoc-openapi-demos/blob/master/springdoc-openapi[…]a/org/springdoc/demo/app4/WebfluxFunctionalDemoApplication.java

[Topher Lamey]

Oh, here’s something using @RouterOperations in a different example: https://github.com/springdoc/springdoc-openapi/blob/master/springdoc-openapi-webfl[…]est/java/test/org/springdoc/api/app69/RoutingConfiguration.java

[Topher Lamey]

This one’s using both @RouterOperations and @RouterOperation: https://github.com/springdoc/springdoc-openapi/blob/master/springdoc-openapi-webfl[…]java/test/org/springdoc/api/app71/EmployeeFunctionalConfig.java

[Topher Lamey]

It’s using the @Bean annotation, which it sounds like you are not using in favor of the Kotlin DSL bean functional stuff

[Adam Crane]

correct, I'm not using the annotations, which is what I'm struggling with...

[Topher Lamey]

right

[Topher Lamey]

so maybe you’ll have to use GroupedOpenApi

[Adam Crane]

I did try and add that at one point, and it created a group for me, but wouldn't add any endpoints

[Topher Lamey]

Does your setup look like this? https://github.com/sdeleuze/spring-kotlin-functional

[Adam Crane]

essentially, yes
