org.hibernate.HibernateException：没有活动事务，load无效

Question

加载用户数据时出现以下错误。

org.hibernate.HibernateException: load is not valid without active transaction

我正在使用AspectJ编译时编织和弹簧3.O.和Hibernate 3.0

以下是我的代码和配置文件。

@Transactional(propagation = Propagation.REQUIRED, isolation = Isolation.DEFAULT)
public boolean add(User user) {
  getUser(user)
}

public User getUser(User user) {
    Session session = this.getSession();
    User user = ( User ) session.load(User.class, 130);
    return user;
}

配置：

<bean id="hbSessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
    <property name="configLocation">
        <value>classpath:hibernate.cfg.xml</value>
    </property>
    <property name="configurationClass">
        <value>org.hibernate.cfg.AnnotationConfiguration</value>
    </property>
</bean>

<!-- Initializes Transaction manager to handle hibernate transactions -->
<bean id="hbTxManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
    <property name="sessionFactory" ref="hbSessionFactory" />
</bean>

<tx:annotation-driven mode="aspectj" transaction-manager="hbTxManager"/>
