为什么在Spring 3.1和hibernate 4中找到当前线程exception的No Session

我试图配置spring 3.1和hibernate。 我写了一个简单的测试项目。 我有用户域和userDao及其实现

让我告诉你appliationContext

                 ${hibernate.dialect} ${hibernate.show_sql} ${hibernate.connection.pool_size} ${hibernate.show_sql} ${hibernate.hbm2ddl.auto} true=1 false=0    

和UserDaoImpl的一部分

  @Repository public class UserDaoImpl implements UserDao { @Autowired private SessionFactory sessionFactory; @Override public User getUser(Long userId) { if (userId != null && userId > 0) { return (User) sessionFactory.getCurrentSession().get(User.class, userId); } return null; } @Override public void updateUser(User user) { if (user != null) { sessionFactory.getCurrentSession().update(user); } } 

好像没事。 但是当我试图运行我的测试用例时，我就是这个例外。

以前的问题解决了，我有另一个问题：现在我得到了

Answer 1

您必须将传播设置为“REQUIRED”，如下所示：

我不知道这是不是一个spring的虫子。

Answer 2

您的示例项目中没有事务。 加：

并用@Transactional注释你的DAO：

 @Transactional @Repository public class UserDaoImpl implements UserDao 

两个说明：

• 您正在使用@Repository正确标记DAO，但它只处理exception转换：

  这样注释的类符合Spring DataAccessException转换的条件

• 考虑将@Transactional放在更高级别的类（ @Service s）上，请参阅在DAO中使用Spring MVC和Hibernate的正确方法，服务层架构进行讨论

更新到最新的jar。 他们是jira创造的。
