休眠事务未正确回滚

Question

我有 2 个表，即 Item 和 Property，以及映射到这两个表的 hibernate 对象。表项到属性的映射看起来像

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

一个项可以有多个属性。像选择、插入这样的一切都可以正常工作。但是当出现错误时，对属性表的插入不会回滚。

发生的情况是，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，则下次我检索该项目时，它具有 2*N 个属性。

编辑 ---

我的类看起来是

@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);
    ...
}

我正在使用带注释的事务（@Transactional）和 spring 框架，抛出的最低异常是

Answer 1

交易不会“级联”。在 JDBC 级别，事务包括：

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

如果你说有些事情正在提交，有些事情正在回滚，那么你的事务管理就有问题。要么自动提交已打开，要么您实际上多次调用 commit() 。

Answer 2

如果您执行以下操作，事务将由 Spring 在后台进行管理：在 XML 配置中，您需要 1) 启用事务，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 为 http://www。 springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd"
