Spring XML配置aspectj注入bean是ClassNotFoundException

Question

在学习Spring in action 4.5的章节时，遇到了困难，我使用xml配置Spring AspectJ，但始终报告错误：由：java.lang.ClassNotFoundException引起，请帮助我，谢谢。这是我的xml ：

<bean id="performance" class="com.springinaction.aop.concert.PerformanceImpl"/>

    <bean id="criticismEngine" class="com.springinaction.aop.concert.CriticismEngineImpl">
        <property name="criticismPool">
            <list>
                <value>Worst performance ever!</value>
                <value>A must see show!</value>
                <value>I laughed,I cried, then I realized i was at the wrong show</value>
            </list>
        </property>
    </bean>

    <bean class="com.springinaction.aop.concert.CriticAspect" factory-method="aspectOf">
        <property name="criticismEngine" ref="criticismEngine"/>
    </bean>
</beans>

这也是我的方面

public aspect CriticAspect {

    private CriticismEngine criticismEngine;

    public CriticAspect() {
    }

    pointcut performance():execution(* perform(..));

    after()returning:performance(){
        System.out.println(criticismEngine.getCriticism());
    }

    public void setCriticismEngine(CriticismEngine criticismEngine) {
        this.criticismEngine = criticismEngine;
    }
}

但是为什么抛出异常：
