Proxy - ProxyFactoryBean

        ApplicationContext context =
                new ClassPathXmlApplicationContext("aopdemo.xml");
        IDemoModel model = (IDemoModel) context.getBean("demoModelProxy");

        System.out.println(model.hello("jc.liu"));

   <bean id="demoModelProxy"
   class="org.springframework.aop.framework.ProxyFactoryBean">
       <property name="proxyInterfaces">
           <list>

Auto Proxy - BeanNameAutoProxyCreator

        ApplicationContext context =
