webuploader上传大文件后台java怎么接收

Answer 1

if(request.getHeader("content-type")!=null&&"application/x-www-form-urlencoded".equals(request.getHeader("content-type"))){ 
            return null;
//将请求转换成MultipartHttpServletRequest 
        MultipartHttpServletRequest mRequest=(MultipartHttpServletRequest)request; 
        Enumeration<String> ps = mRequest.getParameterNames(); 
        while(ps.hasMoreElements()){ 
            String hname = ps.nextElement(); 
            System.out.println(hname); 
            System.out.println(mRequest.getParameter(hname)); 
        } 
         
      //获值
        String value= mRequest.getParameter("key"); //获取单个数据的时候，取key值
     
        Iterator<String> fns=mRequest.getFileNames();//获取上传的文件列表 
        while(fns.hasNext()){ 
            String s =fns.next(); 

            MultipartFile mFile = mRequest.getFile(s);   
            if(mFile.isEmpty()){ 
                map.put("error", "message"); 
            }else{ 
                String basePath=Constant.BASEPICUPLOADPATH; 
                String dPath= Constant.SDF_PARAM.format(new Date()); 
                File dir = new File(basePath+dPath); 
                if(!dir.exists()){ 
                    dir.mkdirs(); 
                } 
                String originFileName=mFile.getOriginalFilename(); 
                String suffix=originFileName.split("\\.")[originFileName.split("\\.").length-1]; 
                String base64Name=UUID.randomUUID().toString(); 
                File file =  new File(basePath+dPath,base64Name+"."+suffix); 
                try { 
                    FileUtils.copyInputStreamToFile(mFile.getInputStream(),file);//存储文件 
                } catch (IOException e) { 
                    e.printStackTrace(); 
                }   
            } 
        } 
        
        
        //最近刚好在做这方面的，希望能解决你的问题

Answer 2

基本都是通过file来接受的，然后在调用file中的参数通过IO流进行保存

Answer 3

IO读取写入
