vue+element-ui怎么把表单数据和图片一起提交到后端呢？能获取图片大小和名称么？

直接上代码吧，满意希望给我采纳，谢谢

    this.$axios.post('http://localhost:8090/xx/xx/insert', formData, config)
      .then((res) => {

          this.formVisibleAdd = false

        }
      })
      .catch((res) => {

  })

}


@PostMapping(value = "insert", produces = MediaType.APPLICATION_JSON_UTF8_VALUE)
    public CommResult insertTableTeam(HttpServletRequest request, 
                                                                            @RequestParam(value = "name", required = false) String name,
                                                                            @RequestParam(value = "code", required = false) String code,
                                      @RequestParam(value = "file", required = false) MultipartFile file) {


        String rootPath = request.getSession().getServletContext().getRealPath("/");
        if (file != null) {
            String fileName = file.getOriginalFilename();
            if (fileName != null && fileName.trim().length() > 0) {
                String newFileName = FileUtil.uploadFile(rootPath, fileName, file);

            }
        }
                //TODO 添加
        return "success";
    }
