我前台请求可以发送到后端，但是后端提示

@AdaptBy(type = UploadAdaptor.class, args = {"ioc:imageUpload"})
    @POST
    @At("")
    @Ok("json")
    public Object image(@Param("image") TempFile tf, HttpServletRequest req, AdaptorErrorContext err) {

            } else if (tf == null) {

        }
    }

这是后台代码

<FormItem
        {...formItemLayout}
        label="上传身份证照片"
        extra="点击上传身份证照片"
      >
        {form.getFieldDecorator('image', {
          valuePropName: 'file',
          getValueFromEvent: normFile,
        })(
          <Upload
            name="image"
            action="/api/upload"
            onPreview={handlePreview}
            listType="picture-card"
          >
            {uploadButton}
          </Upload>
        )}
      </FormItem>
