目標物件
Target.java

public class Target {
    public void save(){
        System.out.println("running......");
    }
}

通知，加強類
Advice.java

public class Advice {
    public void before(){
        System.out.println("前置加強");
    }

    public void afterRunning
 
(){
        System.out.println("後置加強");
    }
}

import java.lang.reflect.Method;

public class cglibTest {

       final Advice advice = new Advice();
       //返回值就是動態代理物件 基於cglib
        //建立增強器
        Enhancer enhancer = new Enhancer();
        //設定父類（目標）
        enhancer.setSuperclass(Target.class);
        //設定回撥
 

        enhancer.setCallback(new MethodInterceptor() {
            public Object intercept(Object proxy, Method method, Object[] ages, MethodProxy methodProxy) throws Throwable {
                advice.before();//執行前置
                Object invoke = method.invoke(target, ages);//執行目標
                advice.afterRunning();//執行後置
                return invoke;
            }

        //建立代理物件
        Target proxy = (Target) enhancer.create();
