Spring学习十四：使用CGLIB实现AOP功能与AOP概念解释

package com.learn.aop;

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 CGLibProxyFactory implements MethodInterceptor{

	private Object targetObject;//代理的目标对象	
	public Object createProxyInstance(Object targetObject){
		this.targetObject = targetObject;
		Enhancer enhancer = new Enhancer();//该类用于生成代理对象
		enhancer.setSuperclass(this.targetObject.getClass());//设置父类
		enhancer.setCallback(this);//设置回调用对象为本身
		return enhancer.create();
	}
	public Object intercept(Object proxy, Method method, Object[] args,
			MethodProxy methodProxy) throws Throwable {
		return methodProxy.invoke(this.targetObject, args);
	}

}

@Test
public void testCGLib() {
	// 业务代理类
	CGLibProxyFactory factory = new CGLibProxyFactory();
	// 元对象(被代理对象)
	PersonServiceImpl service = (PersonServiceImpl)factory.createProxyInstance(new PersonServiceImpl("hwl"));
	service.save("hwl");
}
