一：JDK动态代理

package com.zkn.newlearn.proxyhandler;import java.lang.reflect.InvocationHandler;import java.lang.reflect.Method;import java.lang.reflect.Proxy;import org.omg.CORBA.portable.InvokeHandler;/** *  * @author zkn * 此代理类 代理实现接口的类 * */public class JdkProxyHandler implements InvocationHandler {	private Object targetObject;		public Object createObject(Object obj){		this.targetObject = obj;		return Proxy.newProxyInstance(targetObject.getClass().getClassLoader(), 				targetObject.getClass().getInterfaces(), this);	}		public Object invoke(Object proxy, Method method, Object[] args)			throws Throwable {				return method.invoke(targetObject, args);	}	}

2：CGLIB动态代理

package com.zkn.newlearn.proxyhandler;import java.lang.reflect.Method;import net.sf.cglib.proxy.Enhancer;import net.sf.cglib.proxy.MethodInterceptor;import net.sf.cglib.proxy.MethodProxy;/** *  * @author zkn *	代理类不能为final修饰的类 *	此代理类 代理的是没有实现接口的类 */public class CglibProxyHandler implements MethodInterceptor{	/**	 * 代理对象	 */	private Object targetObj;		public Object createObject(Object obj){		this.targetObj = obj;		Enhancer eh = new Enhancer();		eh.setSuperclass(this.targetObj.getClass());		eh.setCallback(this);		return eh.create();	}		public Object intercept(Object obj, Method arg1, Object[] arg2,			MethodProxy proxy) throws Throwable {				Object object = proxy.invoke(this.targetObj, arg2);//这里如果换成obj 会陷入死循环中		return object;	}	}
