Hibernate @OneToMany / @ManyToOne column not appearing

Question

I have a @OneToMany / @ManyToOne relationship, where a Project can have one or many Phases and a Phase depends on a Project. Pretty simple.

Here are my entities (the relevant parts):

@Entity
@Table(name = "project")
public class ProjectEntity {

    @Id
    @Column(name = "project_id")
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Long id;

    // Our Set of phases to be saved in the database as an array 
    @OneToMany(targetEntity = PhaseEntity.class)
    private Set<PhaseEntity> phases = new HashSet<>(0);

    // Getters and setters
}

And my PhaseEntity:

@Entity
@Table(name = "phase")
public class PhaseEntity {
    @Id
    @Column(unique = true, name="phase_id")
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Long id;

    // Our project on which the phases are appart of   
    @NotNull
    @ManyToOne(targetEntity = ProjectEntity.class)
    private ProjectEntity project;

    // Getters and setters
}

Upon creating phases in an already existing project, I save them one by one by creating an entity and

phaseDao.save(phaseEntity);

And finally save the set of phases in my project like such:

project.setPhases(phaseSet);

My phases ARE correctly created and are linked to a project but my projects do not show any sign of phases as they do not have a phases column.

EDIT: Turns out that Hibernate creates a link table called project_phases, is there a way to save an array of phases without creating a link table?

What am I not understanding?

Answer 1

use mappedBy attribute in @OneToMany Annotation

@OneToMany(targetEntity = PhaseEntity.class, mappedby="project")
private Set<PhaseEntity> phases = new HashSet<>(0);
