二 代码

1 CglibMeipo

package CGlib;
import net.sf.cglib.proxy.Enhancer;
import net.sf.cglib.proxy.MethodInterceptor;
import net.sf.cglib.proxy.MethodProxy;


import java.lang.reflect.Method;


public class CglibMeipo implements MethodInterceptor {
    public Object getInstance(Class<?> clazz) throws Exception{
        Enhancer enhancer = new Enhancer();
        enhancer.setSuperclass(clazz);
        enhancer.setCallback(this);
        return enhancer.create();
    }
    private void before(){
        System.out.println("我是媒婆：我给你找对象，现在已经确认你的需求");
        System.out.println("开始物色");
    }


    private void after(){
        System.out.println("如果合适的话，就准备办事");
    }


    @Override
    public Object intercept( Object o, Method method, Object[] objects, MethodProxy methodProxy ) throws Throwable {
        before();
        Object obj = methodProxy.invokeSuper(o,objects);
        after();
        return obj;
    }
}

2 CGLibTest

package CGlib;
import net.sf.cglib.core.DebuggingClassWriter;

public class CGLibTest {
    public static void main(String[] args){
        try {
            System.setProperty(DebuggingClassWriter.DEBUG_LOCATION_PROPERTY,"E://cglib_proxy_class/");
            Customer obj = (Customer)new CglibMeipo().getInstance(Customer.class);
            obj.findLove();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

3 Customer

package CGlib;

public class Customer{
    public void findLove(){
        System.out.println("高富帅");
        System.out.println("身高180cm");
        System.out.println("有6块腹肌");
    }
}

三 测试

我是媒婆：我给你找对象，现在已经确认你的需求
开始物色
高富帅
身高180cm
有6块腹肌
如果合适的话，就准备办事
