I’m facing an issue with Springdoc in my Spring Boot app and could use some help. Here’s the situation: When I use Springdoc version 2.5.0, everything works fine until I add a @ControllerAdvice to my project. At that point, I get this error:
java.lang.NoSuchMethodError: 'void .springframework.web.method.ControllerAdviceBean.<init>(java.lang.Object)'
To fix this, I upgraded to a newer version of Springdoc:

<dependency>
    <groupId>.springdoc</groupId>
    <artifactId>springdoc-openapi-starter-webmvc-ui</artifactId>
    <version>2.8.6</version>
</dependency>

Now, the @ControllerAdvice error is gone, but I’m hitting a new problem: http://localhost:8088/api/v1/v3/api-docs works perfectly (I get the OpenAPI JSON). http://localhost:8088/api/v1/swagger-ui/index.html returns a 404 Not Found. My config:

springdoc:
  default-produces-media-type: "application/json"
server:
  port: 8088
  servlet:
    context-path: /api/v1

I’ve tried: Adding springdoc.swagger-ui.path=/swagger-ui.html and springdoc.swagger-ui.enabled=true. Permitting /swagger-ui/** and /v3/api-docs/** in my Spring Security config. Adding a WebMvcConfigurer to map /swagger-ui/** to classpath:/META-INF/resources/webjars/springdoc-openapi-ui/. Still, I can’t access the Swagger UI—it’s always 404. The API docs endpoint works.

and this my pom.xml
