尝试在数据库中保存数据时出现错误。
我正在使用Spring 3.2.18.RELEASE和Hibernate 4.2.1.Final。
我四处搜寻，发现很少有SO链接（Spring and hibernate: No Session found for current thread）和博客（https://www.mkyong.com/spring/spring-hibernate-no-session-found-for-current-thread/），这为我所讨论的同一问题提供了启示。但是所有这些链接都使用控制器，服务和dao的注释，而我的应用程序则没有。
因此，由于我不打算在不久的将来升级到注释，因此我无法找到有关如何通过纯Spring XML configuration配置或修复与会话相关的问题的解决方案。
但是，我在DAO类中尝试了很少的更改，但我注意到，当我从getCurrentSession()更改为openSession()然后是flush()和close()时， session有效。
由于我在当前项目中将Hibernate从3.x升级到4.x，因此我将不得不更改许多DAO类（从getCurrentSession()到openSession()），以使其正常工作。
我可以继续使用getCurrentSession()时遇到的问题是否有解决方案？
错误：
