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.

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

I store the images inside my Tomcat home location as it will be outside of my project folder(war) and inside the tomcat.

String rootPath = System.getProperty("catalina.home");
File dir = new File(rootPath + File.separator + "images");

The above lines of code will create a folder in tomcat base directory with name 'images'.

This is the one of the best ways to store images.
