I'm adding Swagger to my Spring Webflux service with functional controller. First I was getting this error:
Description: The bean 'swaggerWelcome', defined in class path resource [org/springdoc/webflux/ui/SwaggerConfig.class], could not be registered. A bean with that name has already been defined in class path resource [org/springdoc/webmvc/ui/SwaggerConfig.class] and overriding is disabled.
Action:
Consider renaming one of the beans or enabling overriding by setting spring.main.allow-bean-definition-overriding=true
So I added spring.main.allow-bean-definition-overriding=true to my application.properties file.
And now I'm getting this error:
Description:
Parameter 1 of method swaggerWebMvcConfigurer in org.springdoc.webmvc.ui.SwaggerConfig required a bean of type 'org.springdoc.webmvc.ui.SwaggerIndexTransformer' that could not be found.
Action:
Consider defining a bean of type 'org.springdoc.webmvc.ui.SwaggerIndexTransformer' in your configuration.

The application.properties file contains:
spring.main.allow-bean-definition-overriding=true
Is there a way to avoid this configuration? What is purpose the of the SwaggerIndexTransformer? Because in the website https://springdoc.org/#getting-started they say that "No additional configuration is needed".
The error was that in the pom file the only dependency should be springdoc-openapi-webflux-ui
