Support for Any schema

[sclorng]

Currently if we expose an object, the schema is

@Schema(description = "The value of the characteristic", required = true)
public Object getValue() {
    return value;
}

gives

value:
    description: The value of the characteristic
    type: object

Is it possible to not have the type attribute or just {} when no other attribute are present to express an Any schema ?

@sclorng - you should be able to set the type to null with an org.eclipse.microprofile.openapi.OASFilter implementation. The model that results from the annotation scan would be made available for modification.

This should be supported, reference https://swagger.io/docs/specification/data-models/data-types/#any

@sclorng , you should be able to accomplish this by setting the following property.

mp.openapi.schema.java.lang.Object={ "name": "AnyType" }

Then, given this POJO:

@Schema(name = "TestBean")
class Bean {
    Object any;
}

It will result in something like:

{
  "openapi" : "3.0.3",
  "components" : {
    "schemas" : {
      "TestBean" : {
        "type" : "object",
        "properties" : {
          "any" : {
            "$ref" : "#/components/schemas/AnyType"
          }
        }
      },
      "AnyType" : {}
    }
  }
}
