一、配置文件

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

    <bean id="myService" class="cn.edu.tju.study.service.MyServiceImpl">
    </bean>

    <bean id="myAdvisor" class="cn.edu.tju.study.service.MyAdvisor">
    </bean>

    <bean id="myProxyFactoryBean" class="org.springframework.aop.framework.ProxyFactoryBean">
        <property name="target" >
            <ref bean="myService"/>
        </property>

        <property name="proxyInterfaces">
        <value>cn.edu.tju.study.service.MyService</value>
        </property>

        <property name="interceptorNames">
            <list>
                <value>myAdvisor</value>
            </list>
        </property>
    </bean>




</beans>

二、实现类：

package cn.edu.tju.study.service;

public interface MyService {
    void myMethod();
}

package cn.edu.tju.study.service;

public class MyServiceImpl implements MyService{
    @Override
    public void myMethod() {
        System.out.println("hello world...");
    }
}

package cn.edu.tju.study.service;

import org.aopalliance.intercept.MethodInterceptor;
import org.aopalliance.intercept.MethodInvocation;

public class MyAdvisor implements MethodInterceptor {
    @Override
    public Object invoke(MethodInvocation invocation) throws Throwable {
        System.out.println("before invoke......");
        Object obj = invocation.proceed();
        System.out.println("after invoke......");
        return obj;

    }
}

三、主类：

package cn.edu.tju.study.service;

import org.springframework.beans.factory.support.BeanDefinitionReader;
import org.springframework.beans.factory.support.DefaultListableBeanFactory;
import org.springframework.beans.factory.xml.XmlBeanDefinitionReader;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.context.support.GenericApplicationContext;
import org.springframework.core.io.ClassPathResource;
import org.springframework.core.io.Resource;

public class AopTest {
    public static void main(String[] args) {
/*        GenericApplicationContext context = new GenericApplicationContext();
        new XmlBeanDefinitionReader(context).loadBeanDefinitions("beans14.xml");
        context.refresh();*/

/*
        ApplicationContext context = new ClassPathXmlApplicationContext("beans14.xml");
*/
        Resource resource = new ClassPathResource("beans14.xml");
        DefaultListableBeanFactory factory = new DefaultListableBeanFactory();
        BeanDefinitionReader beanDefinitionReader = new XmlBeanDefinitionReader(factory);
        beanDefinitionReader.loadBeanDefinitions(resource);


        MyService myService = factory.getBean("myProxyFactoryBean", MyService.class);
        myService.myMethod();
        
        int size = myService.getClass().getInterfaces().length;
        
        for(int i = 0; i < size; i ++){
            System.out.println(myService.getClass().getInterfaces()[i]);
        }
    }
}
