Duplicated path getting swagger-config

[apozog]

After migrating from springdoc 2.8.9 to 3.0.3, swagger-ui started to fail because it adds an extra path to swagger-config route.
Main page "/api/swagger-ui/index.html" is loaded, but tries to get config from "/api/api/v3/api-docs/swagger-config" and fails. Notice the duplicated "/api" at the start. I've verified that the right url without the duplication is providing content correctly.

This is my springdoc.properties:

springdoc.packagesToScan=com.example
springdoc.pathsToMatch=/api/**
springdoc.api-docs.path=/api/v3/api-docs
springdoc.api-docs.enabled = true
springdoc.swagger-ui.path=/api/swagger-ui
springdoc.swagger-ui.enabled = true

Notice I've custom paths. It was working seamlessly with previous version. OpenApi doc at /api/v3/api-docs keeps working well.
My dispatcher-servlet is mapped programmatically at /api, and my controllers are at /api/* because I've WebMvcConfigurer.configurePathMatch with UrlPathHelper.setAlwaysUseFullPath(true).
I don't use spring-boot so I've a specific Springdoc configuration class and dependency springdoc-openapi-starter-webmvc-ui:

@Configuration
@ComponentScan(basePackages = { "org.springdoc" })
@Import({ SwaggerConfig.class, SwaggerWebMvcConfigurer.class, JacksonAutoConfiguration.class })
public class SwaggerUiWebMvcConfigurer {
... }

After swagger-config, it also tries to get api-docs with a duplicated path: /api/api/v3/api-docs and also fails to find static resource swagger-ui.css.map. I workarounded at first with a redirection filter from /api/api to /api.

But instead, I saw that Springdoc internally uses spring-boot property spring.mvc.servlet.path, so I've added that property to springdoc.properties and seems to fix it temporarily. I don't use spring-boot, there should be a way to configure this with a springdoc property and not rely on spring-boot.

Also I get rid of UrlPathHelper that is deprecated with Spring 7 and moved all controllers from /api/users to /users. Now the api-docs is generated without the prefix, which is wrong. I changed server from localhost:8080 to localhost:8080/api and that at least make swagger-ui calls to work. But the servletPath should be included in api-docs endpoints too.
