title: How to display app API documentation by using springdoc-openapi-webflux-ui?
body: <p>I read this <a href="https://springdoc.org/demos.html" rel="nofollow noreferrer">https://springdoc.org/demos.html</a> to use springdoc-openapi-webflux-ui. As documentation said I just added <code>springdoc-openapi-webflux-ui</code> library to my app: <code>implementation('org.springdoc:springdoc-openapi-webflux-ui:1.2.26')</code></p>
  <p>Additionally, I customized path to API in application.yml:</p>
  <pre><code>springdoc:
    swagger-ui:
      path: /swagger-ui.html
  </code></pre>
  <p>When I start app, and go to http://localhost:8080/swagger-ui.html, it redirects me to http://localhost:8080/webjars/swagger-ui/index.html?configUrl=/v3/api-docs/swagger-config. In that page, I got an error:</p>
  <pre><code>Whitelabel Error Page
  This application has no configured error view, so you are seeing this as a fallback.

  [7192d9dc] There was an unexpected error (type=Not Found, status=404).
  No matching handler
  </code></pre>
  <p>Question is: Should I add additional configurations to my app to show API documentation?</p>
  <p>PS: I use spring.boot 2.2.2:RELEASE</p>
