Spring AOP的自动代理的一个小Demo无法找到错误所在: BeanNameAutoProxyCreator

我做的小Demo,是关于Spring AOP自动代理的BeanNameAutoProxyCreator这个类,即根据名称来自动代理.我把代码贴出来,还有运行结果,大家帮我看看吧.(我用另一个代理方法,DefaultAdvisorAutoProxyCreator,是没有问题的)

两个被代理的Bean



public class TestBeanA {

	public void sayHello() {

		System.out.println("Hello, Autoproxy");

	}

}



public class BeanB {

	public void sing() {

		System.out.println("有个大中国啊,我们是一家!");

	}

}

我写的前置通知:



import java.lang.reflect.Method;



import org.springframework.aop.MethodBeforeAdvice;



public class BeforeAdvice implements MethodBeforeAdvice {

	@Override

	public void before(Method method, Object[] args, Object target)

			throws Throwable {

		System.out.println(method.getName() + "(),方法即将运行...");

	}

}

XML配置文件:
(我很怀疑是不是配置文件里面的那个过滤的部分写错了)



<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans" 

	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 

	xsi:schemaLocation="http://www.springframework.org/schema/beans 

						http://www.springframework.org/schema/beans/spring-beans.xsd">

	<bean id="beanA" class="com.chenjb.aop.autoproxy.TestBeanA"/>

	<bean id="beanB" class="com.chenjb.aop.autoproxy.BeanB"/>

	<bean id="beforeAdvice" class="com.chenjb.aop.autoproxy.BeforeAdvice"/>

	

	<bean 

		class="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator">

		<property name="beanNames">

			<list>

				<value>Bean*</value>

			</list>

		</property>

		<property name="interceptorNames">

			<list>

				<value>beforeAdvice</value>

			</list>

		</property>

	</bean>

</beans>

测试类:



	@Test

	public void test() {

		ApplicationContext ctx = new ClassPathXmlApplicationContext(

				"autoproxyname.xml", TestBeforeAdvice.class);

		TestBeanA beanA = ctx.getBean("beanA", TestBeanA.class);

		beanA.sayHello();

		BeanB beanB = ctx.getBean("beanB", BeanB.class);

		beanB.sing();

	}

运行结果:
Hello, Autoproxy
有个大中国啊,我们是一家!

运行结果中并没有打印出前置通知里面的那个方法,所以根本就没有执行前置通知,大家帮我看下是哪里出错啦!
