.net传图片 到 javaweb 后台

业务需求：.net写的上位机传图片给javaweb的后台（http请求）

.net 解析图片成base64的数据，以json方式调用java的接口（key：图片名称（1.jap），vale：base64的图片数据）

@PostMapping("/uploadMore")//支持接收多个文件

        String line=null;
        while((line = reader.readLine())!=null){
            buffer.append(line);
        }

        //服务器路径
        String path = request.getScheme() + "://" + request.getServerName() + ":" + request.getServerPort()+BoardConfig.getFileOneMapping();
