Exception [TOPLINK-60] (Oracle TopLink Essentials - 2.0.1 (Build b09d-fcs (12/06/2007))): oracle.toplink.essentials.exceptions.DescriptorException
Exception Description: The method [_toplink_setattribute_vh] or [_toplink_getattribute_vh] is not defined in the object [cn.ctit.vcms.entity.ActorAttribute].
Internal Exception: java.lang.NoSuchMethodException: cn.ctit.vcms.entity.ActorAttribute._toplink_getattribute_vh()
Mapping: oracle.toplink.essentials.mappings.OneToOneMapping[attribute]
Descriptor: RelationalDescriptor(cn.ctit.vcms.entity.ActorAttribute --> [DatabaseTable(titan.actor_attribute)])
上面是异常信息。
解决办法：实体的原因
1. Actor.java
@OneToMany(cascade = CascadeType.ALL, fetch = FetchType.LAZY, mappedBy = "actor")
public Set<ActorAttribute> getActorAttributes() {
return this.actorAttributes;
}
2.ActorAttribute.java
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "attribute_id")
public Attribute getAttribute() {
return this.attribute;
}
上面的配置中两个都是成了LAZY，所有才报错了，解决办法，吧下面那个改成@ManyToOne(fetch = FetchType.EAGER)就好了，即是：
@ManyToOne(fetch = FetchType.EAGER)
@JoinColumn(name = "attribute_id")
public Attribute getAttribute() {
return this.attribute;
}
