cgLib生成动态代理
package com.stono.cglib; import java.lang.reflect.Method; import net.sf.cglib.proxy.Enhancer; import net.sf.cglib.proxy.MethodInterceptor; import net.sf.cglib.proxy.MethodProxy; public class CglibProxy implements MethodInterceptor { private Enhancer enhance = new Enhancer(); public Object getProxy(Class<?> clazz) { // 设置创建子类的类 enhance.setSuperclass(clazz); enhance.setCallback(this); return enhance.create(); } /** * 拦截所有目标类方法的调用<br> * obj 目标类的实例<br> * m 目标方法的反射对象 <br> * args 方法的参数 <br> * proxy 代理类的实例 */ @Override public Object intercept(Object obj, Method m, Object[] args, MethodProxy proxy) throws Throwable { System.out.println("before ....."); // 代理类调用父类的方法 Object invokeSuper = proxy.invokeSuper(obj, args); System.out.println("after ......"); return invokeSuper; } /** * @param args */ public static void main(String[] args) { CglibProxy proxy = new CglibProxy(); Train t = (Train) proxy.getProxy(Train.class); t.move(); } } /** * 被代理的类 * */ class Train { public void move() { System.out.println("train is running!"); } }
cglib的jar包在网上找一下,不能找eclipse之类里面的,有security问题;
