一、定义接口

package cn.edu.tju.study.service;public interface MyService {void myMethod();
}

二、定义实现类：

package cn.edu.tju.study.service;public class MyServiceImpl implements MyService{@Overridepublic void myMethod() {System.out.println("hello world...");}
}

三、定义配置类，配置业务bean、advisor bean、ProxyFactoryBean

package cn.edu.tju.study.service;import org.aopalliance.intercept.MethodInterceptor;
import org.aopalliance.intercept.MethodInvocation;
import org.springframework.aop.MethodBeforeAdvice;
import org.springframework.aop.framework.ProxyFactoryBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;import java.lang.reflect.Method;@Configuration
public class MyConfig {@Beanpublic MyService myService() {return new MyServiceImpl();}//MethodBeforeAdvice@Beanpublic MethodBeforeAdvice beforeAdvice() {MethodBeforeAdvice advice = new MethodBeforeAdvice() {@Overridepublic void before(Method method, Object[] args, Object target) throws Throwable {System.out.println("will call :"+ method);System.out.println("args are: "+args);}};return advice;}//MethodInterceptor@Beanpublic MethodInterceptor methodInterceptor() {MethodInterceptor methodInterceptor = new MethodInterceptor() {@Overridepublic Object invoke(MethodInvocation invocation) throws Throwable {System.out.println("before method invoke......");Object re = invocation.proceed();System.out.println("after method invoke......");return re;}};return methodInterceptor;}//MethodInterceptor2@Beanpublic MethodInterceptor methodInterceptor2() {MethodInterceptor methodInterceptor = new MethodInterceptor() {@Overridepublic Object invoke(MethodInvocation invocation) throws Throwable {System.out.println("before method invoke2......");Object re = invocation.proceed();System.out.println("after method invoke2......");return re;}};return methodInterceptor;}//ProxyFactoryBean@Beanpublic ProxyFactoryBean proxyFactoryBean() {ProxyFactoryBean proxyFactoryBean = new ProxyFactoryBean();proxyFactoryBean.setTargetName("myService");proxyFactoryBean.setInterceptorNames("beforeAdvice", "methodInterceptor", "methodInterceptor2");return proxyFactoryBean;}
}

四、定义主类，获取ProxyFactoryBean并使用

package cn.edu.tju.study.service;import org.springframework.context.annotation.AnnotationConfigApplicationContext;public class AopAnnotationTest {public static void main(String[] args) {AnnotationConfigApplicationContext context = new AnnotationConfigApplicationContext();context.register(MyConfig.class);context.refresh();MyService myService = context.getBean("proxyFactoryBean", MyService.class);myService.myMethod();}
}

五、运行结果
