写了一个登陆，发现一个问题，是在不知道怎么解决了，求各位大哥大姐帮帮忙，万分感谢！
事情经过是这样的：
我在dao使用getCurrentSession()来获取session，但是在运行的时候提示：No CurrentSessionContext configured!
然后百度知道需要加：<prop key="hibernate.current_session_context_class">thread</prop>配置
于是我把这个配置加到hibernate property中，再次运行项目。
接着又发现：createQuery is not valid without active transaction
于是又百度了一下，有人说getCurrentSession()不是事物的那个session还是怎么回事，我水平比较低，也没看太懂
他说去掉：<prop key="hibernate.current_session_context_class">thread</prop>
但是去掉的话又会报第一个错误，有没有人帮忙看看这是怎么回事，谢了！
