The method getRealPath(String) from the type ServletRequest is deprecated

File tempFile = new File(fileName);// 构造临时对象       // String savePath=tempFile.getName();       // //返回上传文件在客户端的完整路径名称       // request.setAttribute("filename", savePath);

//File file = new File(request.getRealPath("/upload"), //此句报错。       File file = new File(request.getSession().getServletContext().getRealPath("/upload"),//改成这句。就Ok咯         tempFile.getName()); // 获取根目录对应的真实物理路径
