解决方案如下

解决方案:

原因是因为配置<aop:pointcut  id="mycut" expression="* com.java.spring..*.*(..)" />
expression时，没有指定"execution"造成的错误。

正确的配置如下：
    <!-- 配置AOP面向切面-->
    <aop:config>
           <!-- 配置需要面向切面的类 -->
         <aop:aspect id="asp" ref="personInterceptor">
             <!-- 配置切入点,指从什么包下面搜索需要配置面向切面的类. -->
             <aop:pointcut  id="mycut" expression="execution(* com.java.spring..*.*(..))" />
             <!-- 前置方法 -->
             <aop:before pointcut-ref="mycut" method="doAccessCheck"/>
             <!--  后置方法-->
             <aop:after-returning pointcut-ref="mycut" method="doAfterRetruing"/>
             <!-- 例外方法 -->
             <aop:after-throwing pointcut-ref="mycut" method="doAfterThrowing"/>
             <!-- 最终方法 -->
             <aop:after pointcut-ref="mycut" method="doAfter"/>
         </aop:aspect>
    </aop:config>

例如：

<bean id = "logInterceptor" class="com.bjsxt.aop.LogInterceptor"></bean>
    <aop:config>
        <aop:pointcut expression="execution(public * com.bjsxt.service..*.add(..))"        
         id="servicePointcut"/>
         <aop:aspect id="logAspect" ref="logInterceptor">
         <aop:before method="before" pointcut-ref="servicePointcut"/>
         </aop:aspect>        
    </aop:config>
