hibernate事务没有正确回滚

Question

我有2个表，比如Item和Property以及映射到两者的hibernate对象。 表Item到Property的映射看起来像

<set name="propertySet" cascade="all-delete-orphan">
    <key column="item_id" not-null="true"/>
    <one-to-many class="Property"/>
</set>

一个项目可以有多个属性。 像select，insert这样的东西都能正常工作。 但是当出现错误时，属性表的插入不会回滚。

会发生的是，如果我正在编辑具有N个属性的项目并在字段中输入无效值，则下次检索该项目时，它具有2 * N个属性。

编辑---

我班上的样子是什么

@Autowired
SessionFactory sessionFactory

@Transactional
public void updateItem(Item i){
    ...
    // The only 2 statements dealing with hibernate or session in this function
    ItemModel im = sessionFactory.getCurrentSession().get(...);

    sessionFactory.getCurrentSession().update(updatedItem);
    ...
}

我使用带弹簧框架的带注释事务（@Transactional），抛出的最低异常是

Answer 1

交易不是“级联”。 在JDBC级别，事务包括：

1. 关闭自动提交
2. 执行一些陈述
3. 调用java.sql.Connection.commit（）或java.sql.Connection.rollback（） 。

如果你说有些东西正在提交而有些东西被回滚，那么你的交易管理就会出现问题。 自动提交已启用或您实际上有多次调用commit（）正在发生。

Answer 2

如果执行以下操作，则由Spring管理事务：在XML配置中，您需要1）启用事务，以及2）配置事务管理器，如下所示：

<tx:annotation-driven />
<bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
    <property name="sessionFactory" ref="mainSessionFactory" />
</bean>

Tx schemaLocation是http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd "
