Writing service and domain objects

The annotations in Spring Boot make it easy to extract parameters and path variables and execute the service. For now, let's mock the response instead of getting the data from the database.

publicclass Product {  privateint id = 1 ;  private String name = "Oranges " ;  privateint catId = 2 ;

Add the getter and setter methods and a constructor that accepts the product ID:

  public Product(int id) {    this.id = id;    }

  public Product() {   }
