openapi-starter-webmvc-ui:2.0.0-RC1 + openapi-security crashes at startup #1904

[aijazkeerio]

Describe the bug
This might be related to issues #1607, #1617, and #1904

***************************
APPLICATION FAILED TO START
***************************

Description:

The bean 'webConversionServiceProvider', defined in class path resource [org/springdoc/core/configuration/SpringDocConfiguration$WebConversionServiceConfiguration.class], could not be registered. A bean with that name has already been defined in class path resource [org/springdoc/core/SpringDocConfiguration$WebConversionServiceConfiguration.class] and overriding is disabled.

Action:

Consider renaming one of the beans or enabling overriding by setting spring.main.allow-bean-definition-overriding=true

To Reproduce
Steps to reproduce the behavior:
Include both dependancies openapi-starter-webmvc-ui:2.0.0-RC1, openapi-security:1.6.12 in a Gradle project using Spring3, OpenApi3. Then start up the application

• What version of spring-boot you are using?
  • 3.0.0-M4
• What modules and versions of springdoc-openapi are you using?
  • openapi-starter-webmvc-ui:2.0.0-RC1
  • openapi-security:1.6.12
• What is the actual and the expected result using OpenAPI Description (yml or json)?
  • JSON
• Provide with a sample code (HelloController) or Test that reproduces the problem

Expected behavior

• A clear and concise description of what you expected to happen.
  • Application starts up and shows Swagger UI which also contains default OAuth Endpoints
• What is the expected result using OpenAPI Description (yml or json)?
  • JSON

Additional context
My project is based on OAuth Server 1.0. And I am trying to show the OAuth Endpoints. As mentioned in this section https://springdoc.org/#spring-security-support, in order to do that I have to include openapi-security.

I tried excluding one of the Classes by doing

@ComponentScan(basePackages = {"org.springdoc.core"}, excludeFilters={
        @ComponentScan.Filter(type= FilterType.ASSIGNABLE_TYPE, value=SpringDocConfiguration.class)})

but was presented with this error

org.springframework.context.annotation.ConflictingBeanDefinitionException: Annotation-specified bean name 'springDocConfigProperties' for bean class [org.springdoc.core.properties.SpringDocConfigProperties] conflicts with existing, non-compatible bean definition of same name and class [org.springdoc.core.SpringDocConfigProperties]

So I tried to remove it from org.springdoc.core.properties and set spring.main.allow-bean-definition-overriding=true and was presented with this

Parameter 0 of method swaggerUiConfigParameters in org.springdoc.webmvc.ui.SwaggerConfig required a bean of type 'org.springdoc.core.properties.SwaggerUiConfigProperties' that could not be found.


Action:

Consider defining a bean of type 'org.springdoc.core.properties.SwaggerUiConfigProperties' in your configuration.

Which is somewhat similar to this issue #1209

@Aijaz2,

Provide a Minimal, Reproducible Example - with HelloController that reproduces the problem
