Hibernate中的异常(不要更改对层叠为"all-delete-orphan"的集合的引用) [英] Exception in Hibernate (Don't change the reference to a collection with cascade="all-delete-orphan")

问题描述

我在休眠状态遇到了一个奇怪的问题.我在项目中使用冬眠和春季.

I am getting a weird problem in hibernate. I am using hibernate and spring in my project.

问题是我有一个父子关系，当我尝试更新父关系时，我遇到了异常

Problem is I am having a parent child relation, and when I try to update the parent I am getting the exception

由以下原因引起:org.hibernate.HibernateException:请勿更改对带有cascade ="all-delete-orphan"的集合的引用

Caused by: org.hibernate.HibernateException: Don't change the reference to a collection with cascade="all-delete-orphan"

以下是映射:

父母:

    <set name="kittens" fetch="join" lazy="false"
        inverse="true" cascade="all-delete-orphan">
        <key>
            <column name="ID" precision="22" scale="0"
                not-null="true" />
        </key>
        <one-to-many
            class="kitten" />
    </set>

孩子:

    <composite-id name="id" class="kittenId">
         <key-property name="kittenId" type="java.lang.Long">
            <column name="Kitten_ID" precision="22" scale="0" />
        </key-property>
       <key-many-to-one name="cat" class="cat">
            <column name="ID" precision="22" scale="0" />
        </key-many-to-one>                   
    </composite-id>

我在一个论坛中找到并尝试像

I found in a forum and tried changing like

public void setKittens(Set kittens) {
    this.kittens.clear(); 
    this.kittens.addAll(kittens); 
} 

但是现在我要面对

org.hibernate.PropertyAccessException:在小猫的设置器中发生了异常

org.hibernate.PropertyAccessException: Exception occurred inside setter of Kittens

任何帮助将不胜感激.

推荐答案

我遇到了同样的问题.就我而言，问题是，我错误地而不是将update(Entinty e)称为save(Entity e)并得到了此错误.

I had same problem. In my case problem was, that I, by mistake, instead of update(Entinty e) called save(Entity e) and got this error.
