How to display app API documentation by using springdoc-openapi-webflux-ui?

Question

I read this https://springdoc.github.io/springdoc-openapi-demos/ documentation to use springdoc-openapi-webflux-ui. As documentation said I just added springdoc-openap

Answer 1

By default, you just need to add the dependency of the springdoc-openapi-webflux-ui.

 <dependency>
      <groupId>org.springdoc</groupId>
      <artifactId>springdoc-openapi-webflux-ui</artifactId>
      <version>1.2.32</version>
   </dependency>

You can have a look at the demos code:

• https://github.com/springdoc/springdoc-openapi-demos.git-

You can check you classpath, and try to run the application from outside the IDE. Make sure you have the correct settings of your IDE depending on your build Tools:

Also, please check if you are using @EnableWebFlux.

As stated in the Spring Boot reference documentation, when you use @EnableWebFlux, you tell Spring Boot that you wish to take full control over the WebFlux configuration and disable all auto-configuration for this (including static resources):

• https://docs.spring.io/spring-boot/docs/current/reference/html/spring-boot-features.html#boot-features-webflux-auto-configuration

You have two solutions:

1. Remove @EnableWebFlux
2. If you really want take control of Bean creation and you want absolutely to use @EnableWebFlux, then you need to add an implementation of WebFluxConfigurer.
