@OrderColumn annotation in Hibernate 3.5

Question

I\'m trying to use the @OrderColumn annotation with Hibernate 3.5

@OneToMany(mappedBy = \"parent\",fetch=FetchType.EAGER, cascade=CascadeType.AL         


        

Answer 1

Do something like this:

@Entity
class Parent {

    @OneToMany
    @OrderColumn(name = "pos")
    List children;
}

@Entity
class Child {

    @ManyToOne
    Parent parent;
    @Column(name = "pos")
    Integer index;

    @PrePersist
    @PreUpdate
    private void prepareIndex() {
        if (parent != null) {
            index = parent.children.indexOf(this);
        }
    }
}
