.xlsx文件上传，swagger codegn不会为Multipartfile生成@RequestParam

Question

我必须上传存储在 .xlsx 文件中的交易。我正在尝试使用 swagger codegen 生成 api。我浏览了有关该问题的每个 stackoverflow 线程，但没有找到解决方案。

我确实有一个合同：

  /accounts/import/transactions:
    post:
      tags:
        - Account Transaction
      operationId: uploadTransactions
      requestBody:
        content:
          multipart/form-data:
            schema:
              type: object
              properties:
                file:
                  type: string
                  format: binary
      responses:
        200:
          description: 'Upload successful'
        400:
        ...

swagger 依赖项：

<springfox-swagger-ui>3.0.0</springfox-swagger-ui>
<springfox-swagger2>3.0.0</springfox-swagger2>
<swagger-codegen-maven-plugin>3.0.21</swagger-codegen-maven-plugin>

我获得的 API 缺少 @RequestParam("file") MultiPartFile 文件。知道我做错了什么吗？这和 Swagger 版本有什么关系吗？

@RequestMapping(value = "/accounts/import/transactions",
    produces = { "application/json" }, 
    consumes = { "multipart/form-data" },
    method = RequestMethod.POST)
default ResponseEntity<Void> uploadTransactions() {
    if(getObjectMapper().isPresent() && getAcceptHeader().isPresent()) {
    } else {
        log.warn("ObjectMapper or HttpServletRequest not configured in default AccountsApi interface so no example is generated");
    }
    return new ResponseEntity<>(HttpStatus.NOT_IMPLEMENTED);
}
