1. Headers 中类型为空
   
   2.填写测试数据
   
   上传文件时注意选择文件File
   
2. Controller 层相关代码

 @PostMapping(value = "/save")
    public void save(@RequestParam(value = "files") MultipartFile upfiles[], GoodsPicture goodsPicture) throws IOException {

                        String fileName = upfiles[i].getOriginalFilename();
                        File file = new File(url + fileName);
                        // 将MulitpartFile文件转化为file文件格式
                        upfiles[i].transferTo(file);
