swagger没有呈现requestbody

requestBody 不会在夸张的GUI上呈现。我只是得到一个 parameters

paths:
  /my-api:
    post:
      summary: My API Summary
      description: My API Description
      tags:
        - Cost Center
      requestBody:
        required: true
        content:
          application/json:
            schema:
              type: object
              properties:
                data:
                  type: array
                  items:
                    $ref: '#/components/schemas/ReqBodyStruct'

如何使RequestBody也显示在swagger gui中?我错过什么了吗?
