Swagger UI - Aggregate external endpoints using springdoc.swagger-ui.urls.* is not working

Describe the bug I was trying to aggregate external endpoints in one single swagger UI application by following this documentation, but it is not working.

To Reproduce Steps to reproduce the behavior:

• What version of spring-boot you are using? 2.6.0
• What modules and versions of springdoc-openapi are you using? org.springdoc:springdoc-openapi-ui:1.5.13
• Provide with a sample code (HelloController) or Test that reproduces the problem Refer this sample application in github. Using below properties to configure external API, but it is still showing Explore search bar:

springdoc.swagger-ui.urls[0].name=Pet Store
springdoc.swagger-ui.urls[0].url=https://petstore.swagger.io/v2/swagger.json
springdoc.swagger-ui.urls[1].name=Weather
springdoc.swagger-ui.urls[1].url=https://idratherbewriting.com/learnapidoc/docs/openapi_spec_and_generated_ref_docs/openapi_openweathermap.yml

Expected behavior The properties springdoc.swagger-ui.urls.* has no effect, it is still showing Explore search bar. The top bar should show the Select a definition combo with Pet Store and Weather as values.

Screenshots Swagger UI still shows Explore search bar, refer below screen shot:

@asakchris,

The test shouldNotHaveDefaultContent is not correct. It’s normal to have equal contents.

Not that http://localhost:8080/swagger-ui/index.html will return “No API definition provided.” In your case, you should use the following url: http://localhost:8080/swagger-ui/index.html?configUrl=/v3/api-docs/swagger-config.

@bnasslahsen I don’t have the content of html page with “Select a definition”, so I have added a test to make sure html content is not the default one with “Explore” and the test failed. Please refer this test.
