Review Summary

Thank you for your hard work! Before your PR can be approved, there are a few critical issues that need to be addressed. The main problem is that your service implementation classes (CountryServiceImpl, ActorServiceImpl, and MovieServiceImpl) are directly using HibernateUtil.getSessionFactory() instead of accepting a SessionFactory via their constructors, as required by the checklist. Additionally, in your Main.java, you are not passing the SessionFactory to the service implementations when creating their instances. These issues impact the core requirements and functionality of your code. Please refactor your service classes to accept a SessionFactory in their constructors and update Main.java to pass the SessionFactory accordingly. Once these changes are made, your solution should meet all the core requirements. Keep going—you’re almost there! 🚀

+import mate.academy.hibernate.relations.service.impl.ActorServiceImpl;
+import mate.academy.hibernate.relations.service.impl.CountryServiceImpl;
+import mate.academy.hibernate.relations.service.impl.MovieServiceImpl;


Issue: The service implementation instances (CountryServiceImpl, ActorServiceImpl, and MovieServiceImpl) are initialized without passing the required SessionFactory parameter. According to the checklist, you must use the provided SessionFactory when initializing service implementations. Please update these lines to pass sessionFactory to the constructors.

src/main/java/mate/academy/hibernate/relations/service/impl/ActorServiceImpl.java


 public class ActorServiceImpl implements ActorService {
+    private final ActorDao actorDao = new ActorDaoImpl(HibernateUtil.getSessionFactory());


Issue: The ActorDao is initialized with HibernateUtil.getSessionFactory() directly in the field declaration. According to the checklist, service implementations must be initialized with the provided SessionFactory, not by directly accessing HibernateUtil. Please refactor this class to accept a SessionFactory in the constructor and use it to initialize ActorDaoImpl.

Issue: The CountryDao is initialized with HibernateUtil.getSessionFactory() directly in the field declaration. According to the checklist, service implementations must be initialized with the provided SessionFactory, not by directly accessing HibernateUtil. Please refactor this class to accept a SessionFactory in the constructor and use it to initialize CountryDaoImpl.

According to the checklist, service implementations must be initialized with the provided SessionFactory, not by directly accessing HibernateUtil. Please refactor this class to accept a SessionFactory in the constructor and use it to initialize MovieDaoImpl.

Review Summary

Thank you for your hard work! However, there are critical issues that need to be addressed before your PR can be approved. The service implementation classes (ActorServiceImpl, CountryServiceImpl, and MovieServiceImpl) must accept both their respective DAO and a SessionFactory in their constructors, as required by the checklist. Additionally, in Main.java, the services should be initialized with both the DAO and the SessionFactory. Please update your constructors and initialization logic accordingly. Once these changes are made, your code will meet the core requirements—keep going, you're almost there! 🚀

+        CountryService countryService = new CountryServiceImpl(countryDao);
+        // TODO: initialize this instance

Issue: The CountryServiceImpl should be initialized with both the countryDao and the sessionFactory, not just the DAO. This does not meet the checklist requirement that service implementations must accept a SessionFactory in their constructors.

Review Summary

Thank you for your submission! 🎉 Your code now meets the core requirements for the task, and all critical issues from previous reviews have been addressed. The constructors for ActorServiceImpl, CountryServiceImpl, and MovieServiceImpl now correctly accept both their respective DAO and the SessionFactory, and the services are properly initialized in Main.java. All model and DAO classes are implemented as required, and exception handling is in place.

However, please note that there were several critical issues initially—specifically, the service implementation constructors and their initialization in Main.java did not follow the checklist (they only accepted the SessionFactory and created new DAO instances internally). This is not a best practice and can lead to tight coupling and reduced flexibility. In the future, always ensure that dependencies are injected via constructors as required, and avoid creating them internally within service classes. This approach will help you write more maintainable and testable code.

I am approving your PR to help you move forward with your learning journey. Please review the comments and feedback carefully, and make sure to apply these best practices in your future work to avoid similar issues. Keep up the good work and continue improving your code! 🚀 If you need more information, consider reading about Dependency Injection and best practices for service and DAO layers in Java applications.
