我一直在尝试为下面的类编写一个Junit测试用例。我能够成功运行一个测试用例。我正在使用session通过服务器从数据库中获取数据。 我试图将会话对象用作不同的实例。它适用于第一种方法，但不适用于任何其他方法。我知道我会犯一些愚蠢的错误。 这是我的班级：

testGetPaginationData的测试用例运行正常。但是当我尝试将会话对象重用于其他方法时，我正在解决以下错误：

谁能告诉我这里做错了什么？我知道它根本不是一个干净的代码，但我是Java新手....
答案 0 :(得分：0)
您不需要在之前的陈述中session=sessionFactory.openSession();。
在你所有的测试中使用
sessionFactory.getCurrentSession().我觉得应该解决你的问题。
同时使用openSession
getCurrentSession来电
