基于jdk动态代理和cglib动态代理实现及区别说明

@Test
public void test(){
    IPerson target = new ManPerson();
    IPerson proxy = (IPerson)Proxy.newProxyInstance(
        target.getClass().getClassLoader(), 
        target.getClass().getInterfaces(), 
        new PersonInvocationHandler(target));
    proxy.eat();
    proxy.sleep();
}
// 代理对象
class PersonInvocationHandler implements InvocationHandler{
    private Object target;
    public PersonInvocationHandler(Object target){
        this.target = target;
    }
    @Override
    public Object invoke(Object proxy, Method method, Object[] args) throws Throwable{
        System.out.println("start");
    Object result = method.invoke(target, args);
    System.out.println("end");
    return result;
    }
}
// 目标对象

    @Override
    public void eat(){
    System.out.println("吃饭中......");
    }
    @Override

// 目标对象接口
