spring复习:(34)配置文件的方式创建ProxyFactoryBean

一、配置文件




    
    

    
    

    
        
            
        

        
        cn.edu.tju.study.service.MyService
        

        
            
                myAdvisor
            
        
    





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]);
        }
    }
}
