休眠删除查询的顺序

这是我的数据模型(简化)

public class AddressBook {
    private List<Group> groups = new ArrayList<Group>();
    private List<People> peoples = new ArrayList<People>();

    @OneToMany(mappedBy = "addressbook", cascade = CascadeType.ALL, fetch = FetchType.LAZY)
    @OnDelete(action = OnDeleteAction.CASCADE)
    @Cascade(org.hibernate.annotations.CascadeType.DELETE_ORPHAN)
    public List<Group> getGroups() {
        return groups;
    }

    @OneToMany(mappedBy = "addressbook", cascade = CascadeType.ALL, fetch = FetchType.LAZY)
    @OnDelete(action = OnDeleteAction.CASCADE)
    @Cascade(org.hibernate.annotations.CascadeType.DELETE_ORPHAN)
    public List<People> getPeoples() {
        return peoples;
    }
}


public class Group {
    private AddressBook addressBook;


    @ManyToOne(fetch = FetchType.LAZY, optional = false)
    public void setAddressBook(AddressBook addressBook) {
        this.addressBook = addressBook;
    }
}

public class People {
    private AddressBook addressBook;
    private Group group;

    @ManyToOne(fetch = FetchType.LAZY, optional = false)
    public AddressBook getAddressBook() {
        return addressBook;
    }
    public Group getGroup() {
        return group;
    }
}

我想从我的通讯簿中删除一个完整的组,以及属于该组的所有人。所以我做了如下的事情:

adressBook.getPeople().removeAll(peopleBelongingToGroupA);
adressBook.getGroups().remove(groupA);

但是当我的事务被提交时,Hibernate会先执行以下操作:

delete from groups where groupName='groupA';

而不是先删除人员。这就违反了我在人和团体之间的外键限制。

有没有方法告诉Hibernate先删除用户,然后删除组?我的模型有缺陷吗?
