Hibernate - create User service

We will continue working on our Cinema project.

Your task is to implement the following steps:

• Create models:

  • User

• Create DAO:

  • UserDAO

• Create service:

  • UserService:

    public interface UserService {
        User add(User user);
    
        Optional<User> findByEmail(String email); // we will use this `Optional` later
    }

  • AuthenticationService

    public interface AuthenticationService {
        User login(String email, String password) throws AuthenticationException;
    
        /**
        * We should register a new user. New user entity will contains the email and password
        * @param email - user email. should be unique for each user
        * @param password - user password
        * @return new user instance
        */
        User register(String email, String password) throws RegistrationException;
    }

  • Create your own checked RegistrationException and AuthenticationException to use it in register() and login() methods respectively

  • Please don’t forget to use salt and password hashing

• In the mate/academy/Main.main() method create instance of AuthenticationService using injector and test all methods from it.
