嗨,基本上我有这个映射:
@Entity
@Table(schema="xas",name="billing")
public class Billing implements Serializable{
private String id;
private List<Subtotal> subtotals = new ArrayList<Subtotal>(3);
@Id
@Column(name = "id", nullable = false,length=32)
public String getId() {
return id;
}
.....
public void addSubtotal(Subtotal subtotal) {
subtotals.add(subtotal);
}
@OneToMany(cascade=CascadeType.ALL,fetch=FetchType.EAGER)
@JoinColumn(name="billing_id")
@IndexColumn(name="idx")
@Cascade(org.hibernate.annotations.CascadeType.DELETE_ORPHAN)
public List<Subtotal> getSubtotals() {
return subtotals;
}
public void setSubtotals(List<Subtotal> subtotals) {
this.subtotals = subtotals;
}
}
当我查询结算时:
Criteria criteria = session.createCriteria(Billing.class);
criteria.add(Restrictions.in("id", ids));
List<Billing> list = criteria.list();
我基本上得到了这个查询,它将检索我而不是一个结算二:
select *
from oopfmobiles.billing this_
left outer join Subtotal subtotals2_ on this_.id=subtotals2_.billing_id
where this_.id in ('an_id')
怎么了?提前谢谢。
答案 0 :(得分:0)
ids变量的内容是什么? 您是否两次收到相同的结算实例?
如果是这样,您必须确保使用DistinctRootEntityTransformer。
