Spring AOP没有起作用5

接口IAccount:

package study.spring.aop.account;

import java.util.List;

public interface IAccount {
	
	public List<String> getAllAccount();
	
	public String getAccountById(String id);
}

实现类：

package study.spring.aop.account.impl;

import java.util.List;

import study.spring.aop.account.IAccount;

public class AccountImpl implements IAccount {

	public List<String> getAllAccount() {
		// TODO Auto-generated method stub
		return null;
	}

	public String getAccountById(String id) {
		// TODO Auto-generated method stub
		return null;
	}

}

Advice类：

package study.spring.aop.advice;

import java.lang.reflect.Method;

import org.springframework.aop.MethodBeforeAdvice;

public class MyBeforeMethodAdvice implements MethodBeforeAdvice {

	public void before(Method method, Object[] args, Object target)
			throws Throwable {
		
		System.out.println("方法调用之前...");
		System.out.println("下面是方法调用的信息：");
		System.out.println("所执行的方法是:" + method);
		System.out.println("调用方法的参数是：" + args);
		System.out.println("目标对象是：" + target);
	}

}

Spring 配置文件：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN 2.0//EN" "http://www.springframework.org/dtd/spring-beans-2.0.dtd">
<beans default-autowire="byName" default-lazy-init="true">
	
	<bean id="account" class="study.spring.aop.account.impl.AccountImpl" />
	
	<!--  第一个拦截器-->
	<bean id="myBeforeAdvice" class="study.spring.aop.advice.MyBeforeMethodAdvice"/>
	
	<!--  使用ProxyFactoryBean 产生代理对象-->
	<bean id="accountProxy" class="org.springframework.aop.framework.ProxyFactoryBean">
		
		<!-- 设置目标对象 -->
		<property name="target">
			<ref bean="account" />
		</property>
		
		<!-- 这里是代理的接口 -->
		<property name="proxyInterfaces">
			<list>
				<value>study.spring.aop.account.IAccount</value>
			</list>
		</property>
		
		<!--  代理对象所使用的拦截器-->
		<property name="interceptorNames">
			<list>
				<value>myBeforeAdvice</value>
			</list>
		</property>
	</bean>
</beans>

测试代码：

package study.spring.aop;

import org.springframework.test.AbstractSingleSpringContextTests;

import study.spring.aop.account.IAccount;

public class SpringTest extends AbstractSingleSpringContextTests {
	
	@Override
	protected String[] getConfigLocations() {
		return new String[] { "classpath:applicationContext.xml" };
	}
	
	public void testApp() {
		IAccount account = (IAccount) this.getApplicationContext().getBean("account");
		account.getAccountById("1");
	}
}

运行测试代码，advice里的输出为什么没有打印，求指教，谢谢大家。
