獲取動態代理對象

JDK獲取代理對象

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;//目標對象
    
    //單例模式
    private JDKProxyFactory() {}
    
    public static JDKProxyFactory getInstance() {
        return new JDKProxyFactory();
    }
    
    public Object getProxy(Class clazz)throws Exception{
        //獲得目標類型的實例對象
        target = clazz.newInstance();
        //根據目標類型對象創建代理對象
        Object proxy = Proxy.newProxyInstance(clazz.getClassLoader(), 
                clazz.getInterfaces(), this);
        return proxy;
    }
}

 

CGLIB獲取代理對象

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;  //目標對象

        //單例模式
    private CGLIBProxyFactory() {}  //無參私有化構造方法
    public static CGLIBProxyFactory getInstance() {
         //獲取唯一實例
        return new CGLIBProxyFactory();
    }
        
    public Object getProxy(Class clazz)throws Exception{
        //獲得目標對象的實例對象
        target = clazz.newInstance();
        Enhancer enhancer =new Enhancer();
        enhancer.setSuperclass(clazz);
        enhancer.setCallback(this);
        return enhancer.create();
    }
}
