1. 개요

Swagger2 및 UI 버전을 3.0.0으로 잡았을 때 /swagger-ui.html가 열리지 않는 현상

2. 해결

잘 모르겠으나 2.9.2로 되돌리고 나서는 잘 된다.

4. 참고

4.1. SwaggerConfig

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

@Configuration
@EnableSwagger2
public class SwaggerConfig {
    @Bean
    public Docket api() { 

        return new Docket(DocumentationType.SWAGGER_2)  
          .select()                                  
          .apis(RequestHandlerSelectors.any())              
          .paths(PathSelectors.any())                          
          .build();                                           
    }
}
