java - org.hibernate.HibernateException : No Session found

Question

嗨，我面临一个非常奇怪的问题。我正在使用 Spring MVC 3.0+Spring Security 3.2+hibernate 4.3。在登录之前，我可以在登录之前访问数据库并获取实体。但是通过 spring security 登录后，我收到异常 org.hibernate.HibernateException: No Session found for current thread 。 sessionFactory.getCurrentSession() 上抛出此异常

我使用了 AOP 的横切管理。我的问题是:

为什么登录后出现异常？登录前工作正常吗？

我的代码如下:

@Repository("categoryDAO")
public class CategoryDAOHibernateImpl implements CategoryDAO {

@Autowired
SessionFactory sessionFactory;

public List<Category> findAll() {
    List<Category> list;
    try {
        Session session = sessionFactory.getCurrentSession();
        Criteria criteria = session.createCriteria(Category.class);
        list = criteria.list();
    } catch (Exception e) {
        throw new BookStoreDAORuntimeException(e.getMessage(), e);
    }
    return list;
}
}

Answer 1

代码尝试获取当前 session ，但 @Transactional 没有配置允许容器在调用带注释的方法之前将 session 添加到线程。

在堆栈跟踪中，我们可以看到 LibreryController 调用 UserManagementServiceImpl，后者又调用 UserDAOHibernateImpl，并且中间没有事务代理。

您应该添加对@Transactional的支持，用它注释UserManagementServiceImpl，这应该可以解决问题。看这个blog post了解如何执行此操作。
