问题内容：

我正在尝试使用Hibernate
5创建或更新用户，并且抛出以下异常：org.hibernate.resource.jdbc.internal.LogicalConnectionManagedImpl@779de014已关闭

我正在使用以下技术：

Spring 4

*Dormancy 5

*Marvin

*Erosion

这是我的UserDaoImpl.Java：

package com.fasttrack.users.dao;
import java.util.List;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;
import org.springframework.transaction.annotation.Transactional;
import com.fasttrack.users.model.User;

@Repository
@Transactional
public class UserDaoImpl extends AbstractDao implements UserDao
{
    @Autowired
    private SessionFactory sessionFactory;
    public boolean saveUser(User user)
    {
         Session session=sessionFactory.getCurrentSession();
          try
          {
             session.persist(user);
             return true;
          }

          catch (Exception e) 
          {

            e.printStackTrace();
            return false;
        }

          finally 
          {
              session.close(); 
           }

    }


    @SuppressWarnings("unchecked")
    public List<User> getUsers()
    {
         List<User> users;
         Session session=sessionFactory.getCurrentSession();
          try
          {
              users=(List<User>) session.createQuery("FROM USER"); 
              return users;
          }

          catch (Exception e) 
          {
            e.printStackTrace();
        }

          finally {
              session.close(); 
           }
        return null;
    }

    public User getUser(String id)
    {
         User user;
         Session session=sessionFactory.getCurrentSession();
          try
          {
              user=(User)session.get(User.class,id); 
              return user;
          }

          catch (Exception e) 
          {
            e.printStackTrace();
            return null;
        }

          finally 
          {
              session.close(); 
           }

    }



    public boolean updateUser(User user)
    {
        Session session = sessionFactory.getCurrentSession();
        try
            {
                session.saveOrUpdate(user);
                return true;
            }

        catch (Exception e)
            {
                e.printStackTrace();
                return false;
            }

        finally
            {
                session.close();
            }
    }


    public boolean deleteUserById(String id)
    {
        User user = new User();
        user.setId(id);

        Session session = sessionFactory.getCurrentSession();
        try
            {
                session.delete(user);
                return true;
            }

        catch (Exception e)
            {
                e.printStackTrace();
                return false;
            }

        finally
            {
                session.close();
            }
    }

}

这是我的TestUserDao.java：

import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("/Hibernate-test.xml")

public class TestUserDao
{
    @Autowired(required=true)
    public UserDao userDao;

    @Test
    public void testSaveUser()
    {
        User user=new User();
        user.setFirstName("TestUser1");
        boolean result=userDao.saveUser(user);
    }
}

问题答案：

我在您的错误消息“ 严重： 提交异常被回滚异常覆盖
”中发现了一些奇怪的东西。如果查看UserDaoImpl.Java文件中的try块，则具有return语句，该语句在返回之前关闭休眠连接。而且你必须session.close()在finally块声明，没有任何意义，因为连接已经关闭。您介意删除session.close()声明，然后重试。让我知道这是否可以解决您的问题。
