Java Spring in Action 3导致问题的AOP示例

在Action3中，我正在用我的方式处理Spring，其中有一个例子是使用AOP和around方面

这是Aspect类：

package com.xetius.springIdol;

import org.aspectj.lang.ProceedingJoinPoint;

public class Audience {

public void watchPerformance(ProceedingJoinPoint joinpoint) {
    try {
        System.out.println("The audience is taking their seats.");
        System.out.println("The audience is turning off their cell phones.");   
        long start = System.currentTimeMillis();

    joinpoint.proceed();

        long end = System.currentTimeMillis();  
        System.out.println("CLAP CLAP CLAP CLAP CLAP");
        System.out.println("The performance took " + (end - start) + " milliseconds.");
    } catch (Throwable e) {
        System.out.println("Boo! We want our money back!");
    }
}

下面是SpringXML：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:p="http://www.springframework.org/schema/p"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:util="http://www.springframework.org/schema/util"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:aop="http://www.springframework.org/schema/aop"
    xsi:schemaLocation="http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd
        http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-2.0.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">

    <bean id="audience" class="com.xetius.springIdol.Audience" />

    <aop:config>
        <aop:aspect ref="audience">
            <aop:pointcut id="performance2" expression="execution(* com.xetius.springIdol.Performer.perform(..))"/>
            <aop:around pointcut-ref="performance2" method="watchPerformance()"/>
        </aop:aspect>
    </aop:config>
</beans>

我试图使用AOP的Springs实现来实现这一点，但我相信我必须包含AspectJ的一部分来实现这一点

如果我删除参数

ProceedingJoinPoint joinpoint

，则它可以找到此方法。我认为这是一个隐含的参数在方法中为周围的方面。这是正确的吗？如果不是，我做错了什么

我正在使用Maven来构建这个。这是我的POM：

太棒了，谢谢。我已经联系了作者关于这个问题的正确答案。
