（3）PersonService.java类

package com.huawei.aop.factory;
    
    public interface PersonService {
    	
    	public void addPerson();
    	public void updatePerson();
    
    }

（4）（3）PersonServiceImpl.java类

package com.huawei.aop.factory;
    
    public class PersonServiceImpl implements PersonService {
    
    	@Override
    	public void addPerson() {
    		
    		System.out.println("factory addperson");
    	}
    
    	@Override
    	public void updatePerson() {
    		
    		System.out.println("bfactory addperson");
    	}
    
    }

（5）MyAspect.java类

package com.huawei.aop.factory;
    
    import org.aopalliance.intercept.MethodInterceptor;
    import org.aopalliance.intercept.MethodInvocation;
    
    public class MyAspect implements MethodInterceptor {
    
    	@Override
    	public Object invoke(MethodInvocation mi) throws Throwable {
    		
    		System.out.println("before");
    		
    		//执行目标方法
    		Object obj = mi.proceed();
    		
    		System.out.println("after");
    		return obj;
    	}
    
    }

（6）配置文件beans.xml

<?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="personServiceId" class="com.huawei.aop.factory.PersonServiceImpl"></bean>
    	
    	
    	<bean id="myAspect" class="com.huawei.aop.factory.MyAspect"></bean>
    	
    	
    	
    	<bean id="personServiceProxyId" class="org.springframework.aop.framework.ProxyFactoryBean">
    		
    		<property name="proxyInterfaces" value="com.huawei.aop.factory.PersonService"></property>
    		
    		<property name="interceptorNames" value="myAspect"></property>
    		
    		<property name="target" ref="personServiceId"></property>
    		
    		<property name="optimize" value="true"></property>
    	</bean>
    </beans>

（7）单元测试类TestApp.java

package com.huawei.aop.factory;
    
    import org.junit.Test;
    import org.springframework.context.ApplicationContext;
    import org.springframework.context.support.ClassPathXmlApplicationContext;
    
    public class TestApp {
    	@Test
    	public void demo01(){
    		//获得目标类
    		String xmlPath = "/com/huawei/aop/factory/beans.xml";
    		ApplicationContext applicationContext = new ClassPathXmlApplicationContext(xmlPath);
    		PersonService personService = applicationContext.getBean("personServiceId",PersonService.class);
    		personService.addPerson();
    		personService.updatePerson();
    		
    	}
    	@Test
    	public void demo02(){
    		//获得代理类
    		String xmlPath = "/com/huawei/aop/factory/beans.xml";
    		ApplicationContext applicationContext = new ClassPathXmlApplicationContext(xmlPath);
    		PersonService personService = applicationContext.getBean("personServiceProxyId",PersonService.class);
    		personService.addPerson();
    		personService.updatePerson();
    		
    	}
    }
