spring复习：（39）注解方式的ProxyFactoryBean

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{
    @Override
    public 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 {
    @Bean
    public MyService myService() {
        return new MyServiceImpl();
    }

    //MethodBeforeAdvice
    @Bean
    public MethodBeforeAdvice beforeAdvice() {
        MethodBeforeAdvice advice = new MethodBeforeAdvice() {

            @Override
            public 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
    @Bean
    public MethodInterceptor methodInterceptor() {
        MethodInterceptor methodInterceptor = new MethodInterceptor() {
            @Override
            public 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
    @Bean
    public MethodInterceptor methodInterceptor2() {
        MethodInterceptor methodInterceptor = new MethodInterceptor() {
            @Override
            public 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
    @Bean
    public 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
