Hibernate Lazy加载在OneToOne关系中不起作用 [英] Hibernate Lazy loading not work in OneToOne relation
问题描述
在我的公司,我们将一个旧应用程序从Hibernate 2迁移到Hibernate 4.
我的任务是将所有xml实体移动到注释。移动它后,OneToOne关系中的延迟加载停止工作。
In my company we migrated one old app from Hibernate 2 to Hibernate 4. My task was to move all xml entities to annotations. After moving it lazy loading in OneToOne relationship stop working.
entity a xml:
entity a xml:
<id name="entityAid" type="integer" column="entityAid_id">
<one-to-one name="entityB" entity-name="EntityB"
property-ref="entityA" />
entity b xml:
entity b xml:
<property name="entityAid" type="integer" column="entityA_id" />
<many-to-one name="entityA" column="entityA_id" entity-name="EntityA" update="false" insert="false" />
我用代码移动了它:
实体a
@OneToOne(fetch = FetchType.LAZY, mappedBy = "entityA")
private EntityB storageRatecard;
实体b
@ManyToOne
@JoinColumn(name = "entityA_id", insertable = false, updatable = false)
private EntityA entityA;
现在,当我运行app延迟加载不起作用但在xml conf上工作。我发现:
Now when I run app lazy loading not work but worked on xml conf. I found:
但没有任何帮助。(我不能使用字节码检测)
but nothing helps.(I cant use bytecode instrumentation)
我是什么做错了?为什么使用xml一切正常并且注释没有?
What I am doing wrong? Why with xml everything is ok and with annotations no?
推荐答案
mi的工作是懒惰的一对一反向关系。
What work for mi is Lazy one-to-one inverse relationships.
