本人在學習視頻的過程中，手動跟寫代碼，但是在運行的時候，出現了以上的錯誤。根據上面的信息所示，主要是Pointcut is not well-formed: expecting ‘(’ at character position 0 pointcut1這個錯誤信息。本人的xml錯誤配置如下：

<aop:config>
	<!-- 配置切入點 -->
	<aop:pointcut expression="execution(* demo3.AccountService+.*(..))" id="pointcut1"/>
	<!-- 配置切面 -->
	<aop:advisor advice-ref="txAdvice" pointcut="pointcut1"/>
</aop:config>

搜索了網上的相關信息，基本上是提示execution(*跟demo3之間沒有空格顯示，所以報錯，但是檢查了以便，發現去確實有空格存在。所以，本人再次跟着視頻敲打了一遍代碼，發現了這個錯誤所在。正確的代碼如下所示：

<aop:config>
	<!-- 配置切入點 -->
	<aop:pointcut expression="execution(* demo3.AccountService+.*(..))" id="pointcut1"/>
	<!-- 配置切面 -->
	<aop:advisor advice-ref="txAdvice" pointcut-ref="pointcut1"/>
</aop:config>

很明顯，我把pointcut-ref="pointcut1"屬性寫成了pointcut=“pointcut1”，所以發生了錯誤，但是運行的報錯沒有提示到pointcut-ref字眼，所以查找了半天。本內容是小白遇到的問題，有需要的可以蠻看下。
