INNER JOIN无法在休眠状态下工作？

Question

I have a oneToMany association between Movie and actor Table and a ManyToOne association reverse way. One JOIN works but when I have a filter clause in JOIN it fails. please find the relevant code sections with comments above it describing it.

I have read this post. But this did not help Join Query not working in Hibernate

Here are the relevant parts in my Entity:

@Entity
public class Movie {
    ......
    @OneToMany(mappedBy="movie",fetch=FetchType.EAGER,cascade=CascadeType.ALL)
    private Set<Actor> actors=new HashSet<>();
    //getters and setters
}

@Entity
public class Actor {
    .....
    @ManyToOne(fetch=FetchType.EAGER)
    @JoinColumn(name="ACTOR_MOVIE")
    //getters and setters
}

Here is my HibernateTest class:

public class HibernateTest {

    public static void main(String[] args) {
       Movie movie1 = new Movie("Mr and Mrs.Smith", new Date(2005, 6, 5));
        Actor actor3=new Actor("Brad");
        actor3.setMovie(movie1);
        Actor actor4=new Actor("Joe"); 
        actor4.setMovie(movie1); 
        movie1.getActors().add(actor3);
        movie1.getActors().add(actor4);

        Movie movie = new Movie("Titanic", new Date(1997,12,19));
        Actor actor1=new Actor("Leo");
        Actor actor2=new Actor("Kate");
        actor1.setMovie(movie);
        actor2.setMovie(movie); 
        movie.getActors().add(actor1); 
        movie.getActors().add(actor2); 

        SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory();
        Session session = sessionFactory.openSession();
        session.beginTransaction();
        session.persist(movie);
        session.persist(movie1);

        session.getTransaction().commit();
        session.close();

        session = sessionFactory.openSession();
        session.beginTransaction();

        //The following query works
        //List<Object[]> actor_from_movies=session.createQuery("select m.name,act.name from Movie m INNER JOIN m.actors act").list();

        //This throws error        
        List<Object[]> actor_from_movies=session.createQuery("select m.name,act.name from Movie m INNER JOIN m.actors act"
                + "where act.name=:acname").setParameter("acname", "Brad").list();

       System.out.println("actor_from_movies "+ actor_from_movies);

       session.getTransaction().commit();
    session.close();
}
}

Answer 1

在以下位置之前添加空白：

" where act.name=:acname").
