Answer 1

After googling so many thins, I found a solution to this issue. I had to add an additional configuration class that is OpenApiConfig.java to make it work.

@Configuration
@EnableWebMvc
@ComponentScan(basePackages = {"org.springdoc"})
@Import({org.springdoc.core.SpringDocConfiguration.class,
org.springdoc.webmvc.core.SpringDocWebMvcConfiguration.class,
org.springdoc.webmvc.ui.SwaggerConfig.class,
org.springdoc.core.SwaggerUiConfigProperties.class,
org.springdoc.core.SwaggerOAuthProperties.class,
org.springframework.autoconfigure.jackson.JacksonAutoConfiguration.class})
class OpenApiConfig implements WebMvcConfigurer {
}
