org.springframework.orm.hibernate4.HibernateSystemException：请求未知服务[org.hibernate.stat.spi.StatisticsImplementor];

Question

我正在使用hibernate4和spring 3以及jsf2.0 注射我使用注释 我在Google上搜索此例外但未找到任何合适的解决方案 在这里，我发布了我的日志，应用程序上下文和dao实现

Here is my logs

            mSession.close();

        }

    }

Answer 1

在您的DAO代码中关闭整个会话工厂mHibernateSessionFactory.close()是显而易见的。

在工厂关闭后你也无法访问mSession，它在java文档中说明。

void org.hibernate.SessionFactory.close() throws HibernateException

  

销毁此SessionFactory并释放所有资源（缓存，   连接池等）。

     

应用程序有责任确保有   在调用此方法之前没有打开会话作为对这些方法的影响   会议是不确定的。

如果您使用getCurrentSession()方法，典型的模式是将会话开始和结束委派给Spring并使用@Transactional注释

        @Override
        @Transactional
        public void empLogin_Dao(Employee employee) {

            System.out.println("m in dao");

            //Please note that declaring mSession as a class member is another no-no
            //because DAO are typically singletons, so there's only ONE dao and ONE mSession variable 
            //that will be shared by all users - it's possible your class mSession field will be accessed
            //simultaneously, which will lead to an exception
            Session mSession = mHibernateSessionFactory.getCurrentSession();

            System.out.println(employee.getEmpID());

            Query query = mSession
                    .createQuery("from Employee where userName = :username ");
            query.setParameter("username", employee.getUserName());
            List list = query.list(); 
        }
