Mastering Microservices with Java - Third Edition

Service classes

The RestaurantController class uses the RestaurantService interface. RestaurantService is an interface that defines CRUD and some search operations, and is defined as follows:

public interface RestaurantService { 
 
    public void add(Restaurant restaurant) throws Exception; 
 
    public void update(Restaurant restaurant) throws Exception; 
 
    public void delete(String id) throws Exception; 
 
    public Entity findById(String restaurantId) throws Exception; 
 
    public Collection<Restaurant> findByName(String name) throws Exception; 
 
    public Collection<Restaurant> findByCriteria(Map<String, ArrayList<String>> name) throws Exception; 
}
