Feature: Please detect ModelAndView as text/html content

[coding-jj]

Is your feature request related to a problem? Please describe.

• No OpenApi Endpoint is rendered for return type org.springframework.web.servlet.ModelAndView (see example at the end)

Describe the solution you'd like

• springdoc-openapi should detect ModelAndView
• Return OpenApi Document like (mind the "type": "string"):

"responses": {
  "200": {
    "description": "default response",
    "content": {
      "text/html": {
        "schema": {
          "type": "string"
        }
      }
    }
  }
}

Describe alternatives you've considered

Workaround return Object. But this will not produce a correct return type.

@Operation(summary = "Get Status")
@GetMapping(value = "/status", produces = MediaType.TEXT_HTML_VALUE)
public Object getStatus()

OpenApi Response should be "type": "string"

"responses": {
  "200": {
    "description": "default response",
    "content": {
      "text/html": {
        "schema": {
          "type": "object"
        }
      }
    }
  }
}

Additional context

Example:

@Operation(summary = "Get Status")
@GetMapping(value = "/status", produces = MediaType.TEXT_HTML_VALUE)
public ModelAndView getStatus()

Hi @notes-jj,

By default ModelAndView is ignored in springdoc-openapi.
With the next release: v1.2.31, you will be able to display RestControllers that use ModelAndView as well.
For that, you will need to define the following property:

springdoc.model-and-view-allowed=true

If you need to map ModelAndView to a another more convinient type (for example Object), you can just add the following declaration, in any static block:

AdditionalModelsConverter.replaceWithSchema(ModelAndView .class, new ObjectSchema());

You can hava a look at SpringDocApp89Test for more details.
