Case

  • SpringBoot 3.0.4 WebFlux
  • Springdoc 2.0.3
  • Temurin JDK17

Normally starting application cause NO errors at all. Everything is running smooth and well.

During tests (build or manually triggered tests) I'm getting exception:

If you have kotlin classes in your classpath see additionnal dependency you should have:
https://springdoc.org/v2/#kotlin-support

Or you can disable kotlin detection:
springdoc.enable-kotlin=false

If you believe having Other issue, Provide a Minimal, Reproducible Example - with HelloController that reproduces the problem

Edit1: Why then version 2.0.2 was working without any issue?
Edit2: Why are you closing this issue straight away? I was using version 2.0.2 without any problem. I have just upgraded to 2.0.3 and suddenly something went wrong, I didn't change anything in my code (e.g. new Kotlin dependency) except to enter the new version of Springdoc.

For this kind of questions, you should refer to the CHANGELOG: https://github.com/springdoc/springdoc-openapi/releases/tag/v2.0.3

You will find: #2006 - Support for nullable request parameters in Kotlin

It's also clearly stated in the documentation when using kotlin with springdoc-openapi v2:
Your project should add jackson-module-kotlin to the list of dependencies.

NOTE: This dependency is by default transitively included with springdoc-openapi-kotlin module in springdoc-openapi v1.

It's important to make sure you know What librairies you are loading. And what beans you need to load.

The error is enough clear to guide you resolve your project dependencies issue:
It should help you decide whether or not you want enable Kotlin SpringDoc Beans.

As discussed with @breun in another thread,

SpringDocKotlinConfiguration is annotated for checking Kotlin classes presence.
The project is that now in the v2 with the common module - we can not predict the intention of the project.(whether or not they want enable kotlin support)

Most of the comments are for the majority related to project dependencies misconfiguration, or people not reading the documentation for v2 and sometimes people not even knowing they were shipping kotlin classes.

We will consider the change of adding an extra @ConditionalOnClass(KotlinModule.Builder.class) but there will be a trade-off to accept here:

Even if the projects doesn't declare jackson-module-kotlin, the application will start. And there will be no notification for people who misconfigure the kotlin module, leading sometimes to wrong beans loaded and some other times to wrong results.

Great! Thanks. Version 2.0.4 is working as 2.0.2 without any additional properties like springdoc.enable-kotlin=false.
