Java – how to override object array attribute types in RAML 1.0

I have a common Java type, as follows:

class Response<D> {
  List<D> data;
}

And want to create something similar to RAML 1.0 (I'm a novice)

My first way is

types:
  Response:
    type: object
    properties:
      data: object[]

When using it

body:
  type: Response
    properties:
      data: MyDataType[]

From API workbench, I always get an "illegal override of attribute data inherited from response"

Another idea is to use repetition:

types:
  Response:
    type: object
    properties:
      data: object
      repeat: true

And separately

body:
  type: Response
    properties:
      data: MyDataType
      repeat: true

Now the illegal override has disappeared, but in the API console, I now get an "uncapped typeerror"

How? Or do you need a completely different approach? Any ideas?

Solution

It is understood that response abstracts different types of data, but the format is similar One method is to use resources types to abstract the similarity in the response and define specific data in the type
