I will return the following response object SageResponseBody<List<Long>>.

data class SageResponseBody<T>(    
    val data: T
)

Then I tried to define this response object through annotations.

@ApiResponses(
        value = [ApiResponse(
            responseCode = "200",
            description = "request success",
            content = [Content(
                mediaType = MediaType.APPLICATION_JSON_VALUE,
                schema = Schema(type = "object", properties = [StringToClassMapItem(List::class, key = "data")])
            )]
        )]
    )

I can’t set List<Long> and the response object defined is incorrect.

"responses": {
  "200": {
    "description": "request success",
    "content": {
      "application/json": {
        "schema": {
          "type": "object",
          "properties": {
            "data": {
              "type": "string"
            }
          }
        }
      }
    }
  }
}

I’m using swagger 2.x. What is the correct approach?
