一、概述

传入目标对象和Advice(要执行的内容)对“通过反射创建动态代理对象(二)”进行改造(AOP框架实现原理)，建立更加通用的代理对象。

二、代码说明

1、Proxy2IntegrationReform.java

package staticimport.proxy;import java.lang.reflect.InvocationHandler;
import java.lang.reflect.Method;
import java.lang.reflect.Proxy;
import java.util.ArrayList;
import java.util.Collection;import staticimport.proxy.advice.Advice;
import staticimport.proxy.advice.MyAdvice;/**** * 传入目标对象和Advice(要执行的内容)(AOP框架实现原理)* * @author Liu**/
public class Proxy2IntegrationReform {public static void main(String[] args) {Collection<String> target = new ArrayList<>();Collection proxy = (Collection) getProxy(target,new MyAdvice());proxy.add("a");proxy.add("b");proxy.add("c");//     proxy.clear();System.out.println(proxy.size());}private static Object getProxy(final Object target,final Advice advice) {Object object = Proxy.newProxyInstance(target.getClass().getClassLoader(), target.getClass().getInterfaces(), new InvocationHandler() {@Overridepublic Object invoke(Object proxy, Method method, Object[] args) throws Throwable {advice.beforeAdvice(method);Object object = method.invoke(target, args);advice.afterAdvice(method);return object;}});return object;}}

2、接口Advice.java

package staticimport.proxy.advice;import java.lang.reflect.Method;public interface Advice {void beforeAdvice(Method method);void afterAdvice(Method method);
}

3、MyAdvice.java

package staticimport.proxy.advice;import java.lang.reflect.Method;public class MyAdvice implements Advice {private long startTime;@Overridepublic void beforeAdvice(Method method) {startTime = System.currentTimeMillis();}@Overridepublic void afterAdvice(Method method) {long endTime = System.currentTimeMillis();System.out.println(method.getName() + " of time consume: " + (endTime - startTime) + " ms");}}
