 5 import java.lang.reflect.Proxy;
 6 public class JDKProxyFactory implements InvocationHandler{

CGLIB獲取代理物件

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 target;  //目標物件

        //單例模式
    private CGLIBProxyFactory() {}  //無參私有化構造方法
    public static CGLIBProxyFactory getInstance() {
         //獲取唯一例項
        return new CGLIBProxyFactory();
    }
        
    public Object getProxy(Class clazz)throws Exception{
        //獲得目標物件的例項物件
        target = clazz.newInstance();
        Enhancer enhancer =new Enhancer();
        enhancer.setSuperclass(clazz);
        enhancer.setCallback(this);
        return enhancer.create();
    }
