@事务性不使用spring和hibernate

我尝试使用

@Transactional

执行spring事务，但没有成功

摘录自my applicationContext.xml：

<context:annotation-config />
<context:component-scan base-package="hibex" />

<bean id="dataSource"
    class="org.springframework.jdbc.datasource.DriverManagerDataSource"
    p:driverClassName="org.postgresql.Driver" p:url="jdbc:postgresql://localhost:5432/hibex"
    p:username="clubspace" p:password="clubspace" />

<bean id="sessionFactory"
    class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <property name="configLocation" value="classpath:/hibernate.cfg.xml" />
    <property name="entityInterceptor" ref="beanValidationEventListener" />
</bean>

<!-- a PlatformTransactionManager is still required -->
<bean id="transactionManager"
    class="org.springframework.orm.hibernate3.HibernateTransactionManager">
    <!--  org.springframework.transaction.jta.JtaTransactionManager
    org.springframework.jdbc.datasource.DataSourceTransactionManager -->
    <property name="dataSource" ref="dataSource" />
    <property name="sessionFactory" ref="sessionFactory" />
</bean>

<tx:annotation-driven />

<aop:aspectj-autoproxy />

这导致：

1375 [main] ERROR org.hibernate.LazyInitializationException - failed to lazily initialize a collection of role: hibex.bo.OwnerBO.pets, no session or session was closed

从此类调用服务：

@Component
public class App {
    @Autowired
    private Service service;
    public void setService(Service service) {
        this.service = service;
    }
    public void run() {
        service.m2();
    }
}

有什么想法吗

GenericManager位于此处：

获取方法：

public T get(PK id) {
    return dao.findById(id);
}

以及

GenericDaoImpl#findById（PK）

谢谢

Changelog：刚刚添加了额外的信息（必要的代码片段）

异常与Hibernate延迟加载支持有关。 调用owner2.getPets（）.add（）时，Hibernate会话似乎未打开。

---

可能是ownerManager.get（）正在关闭会话吗？

HibernateTransactionManager

应随SessionFactory一起提供，请参见。

能否显示ownerManager.get（）的代码（我怀疑这在您的通用模板中）。问题不在于事务，而在于Hibernate会话在您不想让它打开时被关闭我修改了post以公开get（），我修改了post以包含

get（）

方法“延迟加载也只能在事务或OpenSessionInViewFilter/Interceptor中使用开放的Hibernate会话。“看，如果@Transactional还没有注释，你可能想用@Transactional注释OwnerManager#get方法。那么你是说，我应该在我的

transactionManager

bean中添加

？啊，谢谢，这帮了我的忙（upvote），但不是我问题的最终解决方案

public T get(PK id) {
    return dao.findById(id);
}

public E findById(PK id) {
    return getHibernateTemplate().get(getEntityClass(), id);
}
