[SOLVED] Where to store uploaded images in Linux server using Spring MVC

Where to store uploaded images in Linux server using Spring MVC

I have written a code to upload the images(profile picture of an student) in the server running in linux environment.The code is shown below

 @RequestMapping(value = "/updatePhoto",method = RequestMethod.POST)
public String handleFormUpload(@RequestParam("id") String id,
                               @RequestParam("file") MultipartFile file,
                               HttpServletRequest request,
                               Model model) throws IOException {
    if(!file.isEmpty())
    {
        try
        {
            String relativePath="/resources";
            String absolutePath=request.getServletContext().getRealPath(relativePath);
            System.out.print(absolutePath);
            byte[] bytes=file.getBytes();
            File dir=new File(absolutePath);
            if(!dir.exists())
            {
                dir.mkdir();
            }
            File uploadFile=new File(dir.getAbsolutePath()+File.separator+id+".jpg");
            BufferedOutputStream outputStream=new BufferedOutputStream(new FileOutputStream(uploadFile));
            outputStream.write(bytes);
            outputStream.close();
            model.addAttribute("uploadMessage","image uploaded for id"+id);
        }
        catch (Exception e)
        {
            System.out.print(e);
        }
    }
    return "successFileUpload";

}

i have stored in "/resources" folder.but the problem is, whenever i generate the war file of whole application and deploy in server, it flushes the "/resources" folder and deletes the old uploaded images.Is there any way or the path ,i could upload the images.

Solution

The way I do is:

Create a directory in the server. For example: /myImages
Then grant full permissions for tomcat user

You are good to go now. I have read somewhere that you shouldn't save your stuff on /resources folder because it makes your app independent from container you are using: with tomcat you could use catalina.home but what if you shift to another container
