<!-- 開啟Spring MVC註解 -->

<!-- 配置AOP。Spring是通過AOP來進行事務管理的 -->
<aop:config>
<!-- 設置pointCut表示哪些方法要增加事務處理 -->
<!-- 下面的事務是聲明在DAO中，可是通常都會在Service來處理多個業務對象邏輯的關系，註入刪除，更新等，此時假設在運行了一個步驟之後拋出異常
就會導致數據不完整，所以事務不應該在DAO層處理，而應該在service。這也就是Spring所提供的一個很方便的工具。聲明式事務 -->
<aop:pointcut id="allMethods" expression="execution(* com.myweb.service.*.*(..))" />
<!-- 通過advisor來確定詳細要增加事務控制的方法 -->
