我需要将我的实体映射到oracle中的函数结果。先决条件：
@Entity
@NamedNativeQuery(name="myFunc" query="{?=call MY_FUNC(:param1)}",
resultClass=Test.class, hints={
@QueryHint(name="org.hibernate.callable", value=true)})
public class Test {
@Id @GeneratedValue @Column(name="TEST_ID")
private Long id;
@OneToOne @JoinColumn(name="TEST_ROLE_ID")
private TestRole role;
}
查询：
(List<Test>)entityManager.createNamedQuery("myFunc").setParameter("param1", param1).getResultList();
此外，我还有一个函数，它在Test表（Oracle数据库）上返回REF_CURSOR。
但是当我想添加列
时@OneToOne
@JoinTable(name="V_TEST_REF", joinColumns=@JoinColumn(name="TEST_ID"),
inverseJoinColumns=@JoinColumn(name="REF_ID"))
private TestRef ref;
然后我收到了错误

我该如何解决这个问题？将列添加到函数结果中还是有其他方法吗？
