@Transactional不能与春天和冬眠

Question

我试图做与@Transactional春季交易没有任何成功。从我的applicationContext.xml

摘录：

<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 /> 

我充满春天配置文件是here。

而且我的方法，如果交易不工作：

@Transactional 
public void m2() { 
    OwnerBO owner2 = ownerManager.get(owner.getId()); 
    owner2.getPets().add(new PetBO("Ubul")); 
} 

这会导致：

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

    at hibex.code.App.run(App.java:15) 
    at hibex.code.Main.main(Main.java:14) 

的服务是从这个类叫做：

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

任何想法？

GenericManager是在这里：GenericManager on Pastebin

get方法：

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

而且GenericDaoImpl#findById(PK)

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

感谢

更新日志：只是增加了额外的相关信息（必需的代码段）

Answer 1

这个异常与Hibernate延迟加载支持有关。 当您调用owner2.getPets（）。add（）时，看起来Hibernate会话未打开。 难道是ownerManager.get（）正在关闭Session吗？

Answer 2

HibernateTransactionManager应提供SessionFactory，请参阅javadoc。
