Add our own new method to check whether a particular file is present for that user or not. Create a Service class to store and download files on the server, and to store information in the database.

Here I have used a few more new classes which I will be explaining in a later section of this article, so if you get any compilation issues, ignore them for the moment. There are two important methods in the Service class; one is storeFile , which will store the file at the required location and save the file details in the database. Before storing the file, we will check whether a user has already given the type of file available, and if it is available, then replace the latest file on a server and update the database with the latest information.

Otherwise, it will create a new entry in the database and save the file at the required location. The second method is loadFileAsResource which returns the file as a Resource on the basis of file name given.
