Struts中FormFile是如何读文件的？

Question

使用的是apache common下的fileupload

Answer 1

FormFile workPhoto = form.getWorkPhoto(); //取得上传的文件
        FormFile lifePhoto = form.getLifePhoto();
        String filePath = httpServletRequest.getSession().getServletContext().getRealPath("/");
        if(workPhoto!=null){
            try{
                InputStream stream = workPhoto.getInputStream(); //把文件读入
                /*
                 * 建立一个上传文件的输出流 如果是linux系统请把UploadFiles后的"\\"换成"/"                OutputStream bos = new FileOutputStream(filePath +
                        "lwuser\\fileUpload\\"+fileName);                    int bytesRead = 0;
                    byte[] buffer = new byte[8192];
                    while ((bytesRead = stream.read(buffer, 0, 8192)) != -1)
                    {
                        bos.write(buffer, 0, bytesRead);//将文件写入服务器
                    }
                    bos.close();
                    stream.close();
                    photoPath[0]="\\lwuser\\fileUpload\\"+fileName;            }catch(FileNotFoundException ex){
                System.out.println( "文件上传失败: "+ex);
                throw new FileNotFoundException(ex.toString());
            }catch(IOException ex){
                System.out.println( "文件上传失败: "+ex);
                throw new FileNotFoundException(ex.toString());
            }
        }
