Hibernate's legacy org.hibernate.Criteria API is deprecated;

I am getting warning: Hibernate's legacy org.hibernate.Criteria API is deprecated;

Looks that this course is getting a bit old.

Yes it is already deprecated, but to be fair in those courses where Criteria API is used there are mentions of the latest code to use to fetch data for Hibernate 5.2+ in the Teacher's Notes . It should look like this:

public List<Category> findAll() {
    // Open a session
    Session session = sessionFactory.openSession();

    // DEPRECATED as of Hibernate 5.2.0
    // List<Category> categories = session.createCriteria(Category.class).list();

    // UPDATED: Create CriteriaBuilder
    CriteriaBuilder builder = session.getCriteriaBuilder();

    // UPDATED: Create CriteriaQuery
    CriteriaQuery<Category> criteria = builder.createQuery(Category.class);

    // UPDATED: Specify criteria root
    criteria.from(Category.class);

    // UPDATED: Execute query
    List<Category> categories = session.createQuery(criteria).getResultList();

    // Close session
    session.close();

    return categories;

As you can see it both includes the deprecated and updated code to serve the same purposes as Criteria API.

I hope this helps a little
