我是Spring和Hibernate的新手。我没有找到任何会话当前线程问题。我试着在这里寻找其他线程但不是能够解决我的问题。

也许我缺乏一些概念。请做帮助理解是什么原因以及如何解决和取悦忽略我的格式，我也是stackoverflow的新手。谢谢提前。

UserDaoImpl类

package com.shop.dao.impl;

@Repository
public class UserDaoImpl implements IUserDao {

    private static final Logger LOG =
            Logger.getLogger(UserDaoImpl.class);

    @Autowired
    private SessionFactory sessionFactory;

    @Override
    public boolean checkUser(String email, String password) {
        boolean userFound = false;
        String hql = "from UserInfo where email =? and password=?";
        LOG.info(sessionFactory.getCurrentSession().createQuery(hql));
        Query query = sessionFactory.getCurrentSession().createQuery(hql);
        query.setParameter(0, email);
        query.setParameter(1, password);
        List userList = query.list();

        if ((userList != null) && (userList.size() 0)){
            userFound = true;
        }
        return userFound;
    }

}

在创建查询之前使用sessionFactory的openSession方法：

Session session = sessionFactory.openSession();
Query query = session.createQuery(hql);

完成工作后别忘了关闭会话。

请求处理失败;嵌套异常是org.hibernate.HibernateException：找不到当前线程的Session
