Endpoints with multiple consuming media types not supported

I have a webflux controller like this:

@RestController
@RequestMapping("/foo")
public class FooController {

  @PostMapping(path = "/bar/baz", consumes = "application/x.a+json", produces = MediaType.TEXT_PLAIN_VALUE)
  public String process1(@RequestBody A a) {
    return a.toString();
  }

  @PostMapping(path = "/bar/baz", consumes = "application/x.b+json", produces = MediaType.TEXT_PLAIN_VALUE)
  public String process2(@RequestBody B b) {
    return b.toString();
  }
}

Note that both java methods are bound to the same path - /foo/bar/baz and same HTTP method - POST. The only difference is in the consumed media type.

Spring Boot 2.1.7 supports this and can call the appropriate method based on the content type sent by the client.

However in case of springdoc only one of the methods are exposed. I think the Swagger UI would support multiple different media types because it has a drop down for it but currently it only has one element instead of 2.

I have an endpoint where content can be submitted either as multipart/form-data or as raw JSON in the request body.

The same endpoint, overloaded with two different Accept headers.

This feature is not a priority and the importance should be proven before being addressed. It’s not the natural choice, to create two methods for the same API resource. I will encourage you to refactor and review the design of the APIs instead.

For example, if you have swagger annotation @operation with a description of both, which one will be chosen? The same question for all the fields. summary, operationId.

You will need to clearly define the expected OpenAPI Description as well, using the swagger annotations on both methods.
