Spring Boot and JPA (Java Persistence API), the deleteById method is used to delete an entity by its ID from the database
1. Repository Interface: You typically extend JpaRepository or CrudRepository in your repository interface.
2. Method Definition: deleteById is a predefined method in these repository interfaces, so you don't need to implement it manually. It takes the ID of the entity you want to delete as a parameter.
3. Usage: When you call this method, JPA will generate the appropriate SQL DELETE statement to remove the entity from the database.
