How to use a design pattern to arrange the file structure in a java+spring application

I created a web application which gets the data from the user from the console and stores the data in MongoDB and pass the data to the Angular frontend using Spring rest api.
Whole system is working finely and now I want to rearrange the folder structure according to a design pattern and as shown below I tried to use MVC model but I'm not sure if the file rearrangement is correct I don't know much about design patterns. So please help me with this matter and if the below structure is wrong please help me to make it correct.

Model

Book - Parent class with variables and relevant methods
