Remove Basic Error Controller In SpringFox SwaggerUI

You can restrict the request handler selector to scan only the package of your project:

    return new Docket( DocumentationType.SWAGGER_2)
        .select()
        .apis( RequestHandlerSelectors.basePackage( "your package" ) )
        ...

For example if your parent Package is com.app.microservice

package com.app.microservice;

Then use the following code it will only display the Controllers within the Package and disable/exclude others

@Configuration
@EnableSwagger2
public class SwaggerConfig {

    @Bean
    public Docket api() {
        return new Docket(DocumentationType.SWAGGER_2)
                .select()
                .apis(RequestHandlerSelectors.basePackage("com.app.microservice"))
                .build();
    }

I think, the most elegant solution is to include only @RestController controllers into swagger, only thing to bear in mind, is to annotate all the REST controllers with that annotation:

new Docket(DocumentationType.SWAGGER_2)
            .select()
            .apis(RequestHandlerSelectors.withClassAnnotation(RestController.class))
            .paths(PathSelectors.any())
            .build();

As BasicErrorController is annotated with @Controller only, swagger would avoid BasicErrorController in definition file. Of course you can use your custom annotation instead of @RestController to mark your REST controllers as controllers eligible by swagger.

• It can be done using Predicate.not() .

   @Bean
   public Docket api() {
       return new Docket(DocumentationType.SWAGGER_2)
           .select()
           .apis(RequestHandlerSelectors.any())
           .paths(PathSelectors.any())
           .paths(Predicate.not(PathSelectors.regex("/error.*")))
           .build();
   }
