CGlib动态代理复习

1.要点：

A.代理类实现MethodInterceptor接口 B.复写incept方法； C.使用单例模式进行编写；D.Enhancer.create方法的使用

2.口诀：拦 拦 贷 单
3.Code Show

 */public class CGlibProxy implements MethodInterceptor【拦】 {    private static CGlibProxy instance=new CGlibProxy();    private CGlibProxy() 【单】{    }    public static CGlibProxy getInstance(){        return instance;    }    public <T> T getProxy(Class<T> cls){        return (T) Enhancer.create(cls,this);    }    @Override    public Object intercept【拦】(Object o, Method method, Object[] objects, MethodProxy proxy) throws Throwable {        before();        Object result = proxy.invokeSuper(o, objects);【贷】        after();        return result;    }    public void after() {        System.out.println("前置方法");    }    public void before() {        System.out.println("tango");    }}
