cglib 的动态代理

接着JDK 的动态代理的内容一起写的

①目标类

public class GirlWaiter{

    public void serve() {        System.out.println("上菜");    }}

public class Advice {    public void smile() {        System.out.println("微笑服务");    }

    public void discount() {        System.out.println("打折服务");    }}

②动态代理代码

public class test {

    public static void main(final String[] args) {        final GirlWaiter girlWaiter = new GirlWaiter();//目标对象        final Advice a = new Advice();//增强对象

        //返回值 就是动态生成的代理对象 基于cglib        //1.创建增强器        Enhancer enhancer = new Enhancer();        //2.设置父类        enhancer.setSuperclass(GirlWaiter.class);        //3.设置父类        enhancer.setCallback(new MethodInterceptor() {            public Object intercept(Object o, Method method, Object[] objects, MethodProxy methodProxy) throws Throwable {                a.smile();                Object invoke = method.invoke(girlWaiter, args);                a.discount();                return invoke;            }        });        //4.创建代理对象        GirlWaiter proxy = (GirlWaiter) enhancer.create();        proxy.serve();    }}
