Added Springfox Swagger-UI and it's not working, what am I missing?

Question

Following the instructions here:

http://www.baeldung.com/swagger-2-documentation-for-spring-rest-api

I added these dependencies to my project:

compile "io.springfox:springfox-swagger2:2.7.0" compile "io.springfox:springfox-swagger-ui:2.7.0" 

and configured SpringFox Swagger like this:

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();     } } 

but the Swagger UI seems not to get enabled. I tried:

• http://localhost:8080/swagger-ui.html
• http://localhost:8080/api/swagger-ui.html
• http://localhost:8080/v2/api-docs/swagger-ui.html

and all I get is:

Whitelabel Error Page  This application has no explicit mapping for /error, so you are seeing this as a fallback.  Mon Sep 11 09:43:46 BST 2017 There was an unexpected error (type=Method Not Allowed, status=405). Request method 'GET' not supported 

and on the logs I see:

2017-09-11 09:54:31.020  WARN 15688 --- [nio-8080-exec-6] o.s.web.servlet.PageNotFound             : Request method 'GET' not supported 2017-09-11 09:54:31.020  WARN 15688 --- [nio-8080-exec-6] .w.s.m.s.DefaultHandlerExceptionResolver : Resolved exception caused by Handler execution: org.springframework.web.HttpRequestMethodNotSupportedException: Request method 'GET' not supported 

http://localhost:8080/swagger-resources returns:

[{"name": "default",   "location": "/v2/api-docs",   "swaggerVersion": "2.0"}] 

What am I missing?

Answer 1

Springfox 3.0.0 only works with Spring Boot <= 2.6.0-M2 but not with versions above it

Options for Spring Boot 2.6 M2 <
1. spring.mvc.pathmatch.matching-strategy=ANT_PATH_MATCHER #-> App.properties
    -    But without Actuator
2. @EnableWebMvc
3. Migrate to springdoc-openapi-ui - same steps as io.springfox >= 3.X

io.springfox >= 2.X	io.springfox >= 3.X
