我有2个@RequestMapping;第一个将视频上传到我的服务器，第二个执行转码linux命令。
每个@RequestMapping都在工作，但是我从一周开始尝试从第一个@RequestMapping获取上传文件的文件名并将其发送到第二个。
请帮助我！
这是第一个：
@RequestMapping(value = "/uploadajax", method = RequestMethod.POST)
@ResponseBody
public List<ObjectNode> uploadMultipleFiles(Model model, MultipartHttpServletRequest request, HttpServletResponse response,

serviceMangerTranscode.save(fileMeta);

serviceMangerTranscode.updateFile(fileMeta);
file= fileMeta;
model.addAttribute("Nomf", file.getFileName());
System.out.println("created!!");
String[] cmdArray = {"ffprobe","-show_streams","-i",filepath };
model.addAttribute("filepath",filepath);
System.out.println("ffprobe2........!!");
//String[] cmdArray = {"ping","www.google.com" };

node.put("line",line );
System.out.println("</OUTPUT>");
return listFileNode;
}else {
long size = FileUtils.sizeOfDirectory(repoUSer);
System.out.println("size 1"+(size/1024)/1024);

这是第二个：

答案 0 :(得分：0)
感谢您的回复，我认为无法完成，所以我将数据放入数据库，而不是在第二次RequestMapping中恢复
