Could not obtain transaction-synchronized Session

excel数据导入数据库的小逻辑,断点调试发现走了dao层的save方法,但是并没有sql语句输出,而且数据库也没有数据。用spring-test测试dao层的save方法报错org.hibernate.HibernateException: Could not obtain transaction-synchronized Session for current thread

    记录一下解决方法,我在配置文件中加入了thread之后把dao层改为
    Session session = getCurrentSession();
    Transaction tx = session.beginTransaction();
    try{
    session.save(employ);
    tx.commit();
    }catch(Exception ex){
    tx.rollback();
    }
    之后就可以了,但是还是不知道原因是啥,我配置了事务管理器的,为什么还要在dao层这样操作才行,等大神指导解答

    在Dao实现类上添加一个注解@Transactional
