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();
    }
}
