我有一个实体ENTITY1有一对多关系与ENTITY2如下：无法从@OneToMany集合中删除元素
1 ENTITY1：
@Entity
@Table(name = "Entity1", catalog = "mydb")
public class Entity1 implements java.io.Serializable {
@OneToMany(fetch = FetchType.LAZY, mappedBy = "entity1", cascade = javax.persistence.CascadeType.ALL)
@OrderBy("id")
private Set<Entity2> collection = new HashSet<Entity2>(
0);
}
2-实体2：（等于和重写的哈希码方法）
@Entity
@Table(name = "entity2", catalog = "advertisedb")
public class Entity2 implements java.io.Serializable {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name = "pkid", unique = true, nullable = false)
@Basic(fetch = FetchType.EAGER)
private long id;
@ManyToOne(fetch = FetchType.EAGER)
@JoinColumn(name = "fk_entity1", nullable = false)
private Entity1 entity1;
@ManyToOne(fetch = FetchType.EAGER)
@JoinColumn(name = "apid", nullable = false)
private Entity3 entity3;
}
3-下面是我从集合中移除的实体：
entity1Obj.getEntity2().remove(entity2);
log.debug("size after remove: "+ entity1Obj.getEntity2().size()); // size decreases correctly, so the entity is removed from the collection
entity1Dao.updateEntity1(entity1);
4- DAO方法：
public void updateEntity1(Entity1 entity1) {
getCurrentSession().update(getCurrentSession().merge(entity1));
}
问题：是我所得到的控制台，是应该删除的实体2的选择查询，并且没有删除查询，并且没有被删除。
请指教如何解决此问题。
