spring aop,遇到Session is closed;

[eshore_pal]

背景：使用spring aop记录dao层所发出的所有sql语句。

问题：使用@AfterReturning通知的时候，执行到被拦截的方法是抛了异常--Session is closed; nested exception is org.hibernate.SessionException: Session is closed

异常信息：

补充说明下，换成@Before(value="databasePointCut()")和@Around(value="databasePointCut()")切不会出现这个错误，一切正常
