1、测试 openSession

　　使用openSession() 获取 session, 注释掉 session.close()， 访问测试

    @Override
    public List<FactComsumption> getFactComsumptionList(Integer companyId, Integer merchantId, Integer cityId, String startDate, String endDate) {
        Session session = this.getHibernateTemplate().getSessionFactory().openSession();
        List<FactComsumption> list = FacadeFunctions.getFactTableListByDateInterval(session, FactComsumption.class, "FactComsumption", companyId, merchantId, cityId, startDate, endDate);
　　　　 // session.close();
        return list;
    }

 

　　多次访问进行测试，测试发现第 5 次就会出现下面的情况

　　业务 service 会多次调用 dao层的方法，session没有关闭的话，很快就会用尽

2、测试 getCurrentSession

    @Override
    public List<FactComsumption> getFactComsumptionList(Integer companyId, Integer merchantId, Integer cityId, String startDate, String endDate) {
        Session session = this.getHibernateTemplate().getSessionFactory().getCurrentSession();
        List<FactComsumption> list = FacadeFunctions.getFactTableListByDateInterval(session, FactComsumption.class, "FactComsumption", companyId, merchantId, cityId, startDate, endDate);
        // session.close();
        return list;
    }

　　报错：Calling method ‘createQuery‘ is not valid without an active transaction (Current status: NOT_ACTIVE)"

10:44:13.402 ERROR (DefaultExceptionHandler.java     :56) : Calling method ‘createQuery‘ is not valid without an active transaction (Current status: NOT_ACTIVE)
