vue实现上传文件_vue工程如何打包部署运行

//文件上传
    @PostMapping(value = "/upLoading")
    @ResponseBody
    public Result<HashMap<String,String>> upLoading(MultipartFile file,HttpServletRequest request){ 
   
        System.out.println("进入文件上传");
        //定义要返回的绝对路径和相对路径
        String absolutePath=null;
        String relativePath=null;

        Result<HashMap<String,String>> result = new Result<HashMap<String,String>>();
        //获得服务器所在路径
        String path = request.getSession().getServletContext().getRealPath("/")+file.getOriginalFilename();
        //获得上传文件的文件名
        String fileName=file.getOriginalFilename();
        System.out.println(fileName);
        //xxxxx.xxx
        //UUID.randomUUID()
        //UUID:随机生成一段字符串，16-18位由字母加数字拼接而成，保证10年不重复
        fileName = UUID.randomUUID()+fileName.substring(fileName.lastIndexOf("."));
        System.out.println(fileName);
        //设置绝对路径和文件存储路劲
        absolutePath = "D:\\ideaProjects\\SSMApp\\src\\main\\web\\statics\\uploadfiles\\"+fileName;
        //设置相对文件路径
        relativePath="statics\\uploadfiles\\"+fileName;
        System.out.println(path);
        HashMap<String ,String> map=new HashMap<String, String>();
        map.put("absolutePath",absolutePath);
        map.put("relativePath",relativePath);
        //保存文件
        try { 
   
            file.transferTo(new File(absolutePath));
            result.setResult(map);
            result.setMessage("文件上传成功");
        }catch (Exception exce){ 
   
            result.setMessage("文件上传失败："+exce.getMessage());
            result.setSuccess(false);
            System.out.println(exce.getMessage());
        }
        return result;
    }
