请问一下在 application.xml 配置了这个 aop，为啥访问的时候报错。。。。

<bean id="generatedUUID" class="com.prbp.sdk.interceptor.mybatis.GeneratedUUIDInterceptor"/>
<aop:config>
<aop:aspect id="secutityAspect" ref="generatedUUID">
<aop:pointcut id="saveMethod" expression="execution(* com.prbp..dao..save*(..)) "/>
<aop:before method="checkUUID" pointcut-ref="saveMethod"/>
</aop:aspect>
</aop:config>

<!-- 配置使 Spring 采用 CGLIB 代理 -->
<aop:aspectj-autoproxy proxy-target-class="true"/>
