如何修复java.nio.file.NoSuchFileException：C：\\ Users \\ profilepics \\ default.jpg

Question

我在glassfish服务器中出现错误。 说我的文件夹/文件不存在。 我复制并粘贴了此处说明的路径，并且图像在那里。 我正在显示从这里到我的JSP的图像。

我绝对是初学者。 我正在使用Spring和glassfish4。这是我在Controller中的代码，

 @RequestMapping(value = "/getavatar/{value}", method = RequestMethod.GET)
        public void readImage(HttpServletRequest request, HttpServletResponse response,@PathVariable String value)
                throws ServletException, IOException {
            //int cifid = authenticationFacade.getSessionData().getCifid(); 

            ServletContext sc = request.getServletContext();



            File image = new File(com.aimglobalinc.constants.AimConstants.AVATAR_FOLDER + value + "_avatar.jpg");

            if(!image.exists()){
                image = new File(com.aimglobalinc.constants.AimConstants.AVATAR_FOLDER + "default.jpg");
            } 

            String contentType = sc.getMimeType(image.getName());
            response.reset();
            response.setContentType(contentType);
            response.setHeader("Content-Length", String.valueOf(image.length()));
            Files.copy(image.toPath(), response.getOutputStream());
        }
