获取动态代理对象

JDK获取代理对象

package isoft.proxy;

import java.lang.reflect.InvocationHandler;
import java.lang.reflect.Method;
import java.lang.reflect.Proxy;
public class JDKProxyFactory implements InvocationHandler{
    private Object target;//目标对象
    
    //单例模式
    private JDKProxyFactory() {}
    
    public static JDKProxyFactory getInstance() {
        return new JDKProxyFactory();
    }
    
    public Object getProxy(Class clazz)throws Exception{
        //获得目标类型的实例对象
        target = clazz.newInstance();
        //根据目标类型对象创建代理对象
        Object proxy = Proxy.newProxyInstance(clazz.getClassLoader(), 
                clazz.getInterfaces(), this);
        return proxy;
    }
}

 

CGLIB获取代理对象

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;  //目标对象

        //单例模式
    private CGLIBProxyFactory() {}  //无参私有化构造方法
    public static CGLIBProxyFactory getInstance() {
         //获取唯一实例
        return new CGLIBProxyFactory();
    }
        
    public Object getProxy(Class clazz)throws Exception{
        //获得目标对象的实例对象
        target = clazz.newInstance();
        Enhancer enhancer =new Enhancer();
        enhancer.setSuperclass(clazz);
        enhancer.setCallback(this);
        return enhancer.create();
    }
}
