使用CGLIB实现AOP功能与AOP概念解释

使用CGLIB实现AOP功能与AOP概念解释\

核心代码：

package org.aop.service;

import java.lang.reflect.Method;

import org.aop.service.impl.PersonServiceBean;

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;
 
 public Object  createProxyIntance(Object targetObject){
  this.targetObject=targetObject;
  Enhancer enhancer=new Enhancer();
  enhancer.setSuperclass(this.targetObject.getClass());//非final的方法
  enhancer.setCallback(this);
  return enhancer.create();
 }

 public Object intercept(Object proxy, Method method, Object[] args,
   MethodProxy methodProxy) throws Throwable {
  PersonServiceBean bean=(PersonServiceBean)this.targetObject;
  Object result=null;
  if(bean.getUser()!=null){
    result=methodProxy.invoke(targetObject, args);
  }
  
  return result;
 }
}
