工程路徑

 

 從網上down的demo能正常運行，自己先排錯，把xml中環繞通知隱藏,運行正常，依次把前置通知(before)，后置通知(after)取消隱藏，運行正常，再將after-returning取消隱藏時錯，仔細與demo對比，發現在aop:after-returning的屬性pointcut中是沒有and args(res)的，去掉后運行正常, 因為對aop配置文件還不太熟，原因還不知道，后續確定原因后再記錄。

全部lib文件如下(com.springsource.org.aspectj.weaver-1.6.4.RELEASE.jar是手工下載的,其他都是在建立spring時勾選的download自動下載):
