Hibernate 春季及;休眠:没有绑定到线程的会话
试图让Spring的事务管理工作起来,但并不像我希望的那样 请求任何需要我的数据库的内容时,我会遇到异常:Hibernate 春季及;休眠:没有绑定到线程的会话,hibernate,spring,session,transactions,Hibernate,Spring,Session,Transactions,试图让Spring的事务管理工作起来,但并不像我希望的那样 请求任何需要我的数据库的内容时,我会遇到异常: DEBUG: org.springframework.orm.hibernate3.SessionFactoryUtils - Opening Hibernate Session DEBUG: org.springframework.orm.hibernate3.SessionFactoryUtils - Opening Hibernate Session DEBUG: org.hiber

我已经将我的属性移动到我的Spring上下文中,看看这是否更好,但没有。

有没有人知道我忘记了什么,配置错误?基本思想是,在这种配置下,只要在我的服务层中调用事务方法,就会打开会话。这还允许我在相同的事务方法中加载惰性集合。但由于某些原因,它甚至找不到线程。由于您的配置看起来很好,有几个可能的原因:
- 对使用
创建的对象调用new
方法(即,不是从Spring获得的)@Transactional
- 您从同一对象的另一个方法调用
方法(在这种情况下,事务方面不应用,因为它是基于代理的)@Transactional
- 使用
方法的对象在@Transactional
无效的上下文中声明(例如,您的
对象在@Transactional
中声明,而..-servlet.xml
仅在
中声明)applicationContext.xml
@Repository
public class LeerlingDAOimpl implements LeerlingDAO {
@Autowired
public LeerlingDAOimpl(SessionFactory sessionFactory) {
this.sessionFactory = sessionFactory;
}
