Question

javaweb上传文件不成功

 protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        HttpSession session = request.getSession();
        if(session.getAttribute("username")==null){
            response.sendRedirect(Key.APPLICATION_NAME+"/index.jsp");
            return;
        }
        response.setContentType("text/html;charset=UTF-8");
        String cusId = request.getParameter("cusId");
        String cusName = request.getParameter("cusName");
        String petName = request.getParameter("petName");
        String petBirthday = request.getParameter("petBirthday");
        //说明输入的请求信息采用UTF-8编码方式
        request.setCharacterEncoding("utf-8");
        response.setContentType("text/html; charset=UTF-8");
        PrintWriter out = response.getWriter();
        //Servlet3.0中新引入的方法，用来处理multipart/form-data类型编码的表单
        Part part = request.getPart("petPhoto");
        //获取HTTP头信息headerInfo=（form-data; name="file" filename="文件名"）
        String headerInfo = part.getHeader("content-disposition");
        //从HTTP头信息中获取文件名fileName=（文件名）
        String fileName = headerInfo.substring(headerInfo.lastIndexOf("=") + 2, headerInfo.length() - 1);
        //获得存储上传文件的文件夹路径
        String fileSavingFolder = this.getServletContext().getRealPath("/UpLoad");
        System.out.println("文件保存路径:"+fileSavingFolder);
        //获得存储上传文件的完整路径（文件夹路径+文件名）
        String fileSavingPath = fileSavingFolder + File.separator + fileName;
        System.out.println("fileSavingFolder:"+fileSavingFolder);
        System.out.println("fileSavingPath:"+fileSavingPath);
        //如果存储上传文件的文件夹不存在，则创建文件夹
        File f = new File(fileSavingFolder + File.separator);
        if(!f.exists()){
            f.mkdirs();
        }
        //将上传的文件内容写入服务器文件中
        part.write(fileSavingPath);
        //输出上传成功信息
        out.println("文件上传成功~！");
        String petPhoto =fileSavingPath;
        Pet pet=new Pet();
        pet.setName(petName);
        pet.setBirthdate(petBirthday);
        pet.setPhoto(fileName);
        pet.setOwnerId(Integer.parseInt(cusId));
        try {
            petDAO.save(pet);
        } catch (Exception e) {
            e.printStackTrace();
        }
        response.sendRedirect(APPLICATION_NAME+"/CustomerServlet?id="+cusId);
    }
