很郁闷的错误，终于解决了：
<aop:config>
<aop:aspect ref="log">
<aop:pointcut id="aopTest" expression="execution(*com.gc.action.HelloWorldActionDAO.*(..))"/>
<aop:around method="around" pointcut-ref="aopTest"/>
</aop:aspect>
</aop:config>
严重: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'urlMapping' defined in ServletContext resource [/WEB-INF/spring-servlet.xml]: BeanPostProcessor before instantiation of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.aop.aspectj.AspectJPointcutAdvisor#0': Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [org.springframework.aop.aspectj.AspectJPointcutAdvisor]: Constructor threw exception; nested exception is java.lang.IllegalArgumentException: Pointcut is not well-formed: expecting 'name pattern' at character position 47
execution(*com.gc.action.HelloWorldActionDAO.*(..))
^
修改：
<aop:config>
<aop:aspect ref="log">
<aop:pointcut id="aopTest" expression="execution(* com.gc.action.HelloWorldActionDAO.*(..))"/>
<aop:around method="around" pointcut-ref="aopTest"/>
</aop:aspect>
</aop:config>
在*后面加一个空格，则解决问题，不错不知道啊，望大家能注意啊。
