我举个例子：

openapi: 3.0.3
info:
  title: My App
  version: 1.0.0
tags:
  - name: Order
    description: "Order endpoints"
paths:
  /api/v0/order:
    post:
      tags:
        - Order
      summary: 'Create Order'
      operationId: createOrder
      requestBody:
        content:
          'application/json':
            schema:
              $ref: '#/components/schemas/Order'
        required: true
      responses:
        200:
          description: OK
          content:
            'application/json':
              schema:
                $ref: '#/components/schemas/SuccessMessage'
        400:
          description: Error
          content:
            'application/json':
              schema:
                $ref: '#/components/schemas/ErrorMessage'
components:
  schemas:
    Order:
      type: object
      properties:
        name:
          type: string
        description:
          type: string
        type:
          type: string
    SuccessMessage:
      type: object
      properties:
        code:
          type: string
        message:
          type: string
    ErrorMessage:
      type: object
      properties:
        code:
          type: string
        message:
          type: array
          items:
            type: string

我正在使用Open API Generator来生成代码，但这一个生成的代码如下所示：

@Operation(
    operationId = "createOrder",
    summary = "Create Order",
    tags = { "Order" },
    responses = {
        @ApiResponse(responseCode = "200", description = "OK", content = {
            @Content(mediaType = "application/json", schema = @Schema(implementation = SuccessMessage.class))
        }),
        @ApiResponse(responseCode = "400", description = "Error", content = {
            @Content(mediaType = "application/json", schema = @Schema(implementation = ErrorMessage.class))
        })
    }
)
@RequestMapping(
    method = RequestMethod.POST,
    value = "/api/v0/order",
    produces = { "application/json" },
    consumes = { "application/json" }
)
default ResponseEntity<SuccessMessage> createOrder(
    @Parameter(name = "Order", description = "", required = true) @Valid @RequestBody Order order
) {
    return getDelegate().createOrder(order);
}

正如你所看到的，我有这个default ResponseEntity<SuccessMessage> createOrder，但我的目标是使用泛型类型，而不是像这样：

default ResponseEntity<?> createOrder

有没有办法告诉OpenApiGenerator生成ResponseEntity<?>而不是ResponseEntity<SuccessMessage>，我知道有一个解决方案是使用mustache，但也许有其他的解决方案。
