如何在HIbernate中保存循环中的对象？

// 定义父对象
@Entity
public class Parent {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    @OneToMany(mappedBy = "parent", cascade = CascadeType.ALL)
    private List<Child> children;

    // 省略其他属性和方法
}

// 定义子对象
@Entity
public class Child {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    @ManyToOne
    @JoinColumn(name = "parent_id")
    private Parent parent;

    // 省略其他属性和方法
}

// 保存循环中的对象
Parent parent = new Parent();
Child child1 = new Child();
Child child2 = new Child();

parent.setChildren(Arrays.asList(child1, child2));
child1.setParent(parent);
child2.setParent(parent);

Session session = HibernateUtil.getSessionFactory().getCurrentSession();
session.beginTransaction();

session.save(parent);

session.getTransaction().commit();
