[color=red][b]问题描述：[/b][/color]
整合spring3与hibernate4时，发生错误：[u]nested exception is org.hibernate.HibernateException: No Session found for current thread[/u]
之后查找资料，添加[u]：thread[/u]属性，报错：org.hibernate.HibernateException: createQuery is not valid without active transaction，
查找资料说，删除上面我添加的那个属性，我被陷入死循环了。
[color=red][b]代码如下[/b][/color]

各层次的ioc都OK的，问题出在哪里，或者解答下原因也可以，我自己查找资料，谢谢了。
