JSP直接读取用户下传的文件

JSP直接读取用户上传的文件

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {try {DefaultFileItemFactory factory = new DefaultFileItemFactory();FileUpload sevletFileUpload = new FileUpload(factory);// 设置允许用户上传文件大小,单位:字节，这里设为2msevletFileUpload.setSizeMax(2 * 1024 * 1024);// 设置最多只允许在内存中存储的数据,单位:字节factory.setSizeThreshold(4096);// 开始读取上传信息List fileItems = sevletFileUpload.parseRequest(request);FileItem item = (FileItem)fileItems.get(1);FileItem item2 = (FileItem)fileItems.get(0);String company = item2.getString();                        //处理你的逻辑。。。response.setCharacterEncoding("gb2312");response.getWriter().write("操作完成!请仔细检查上传数据是否正确!");}    catch(DocumentErrorException dee){    dee.printStackTrace();    response.getWriter().write("有错误发生:数据格式不正确!");    }catch (Exception ex) {ex.printStackTrace();response.getWriter().write("有错误发生:"+ex.getMessage());}}
