spring中 FactoryBean和bean

1.整合spring+hibernate中，让spring接管hibernate的session工厂有一段代码

package org.ym.test;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;import org.ymm.entity.TestBean;/** * Tester测试类 * @author witho_000 * */public class Tester {public static void main(String[] args) {ApplicationContext cont=new ClassPathXmlApplicationContext("beans.xml");String s= cont.getBean("&factorybean1",String.class);System.out.println(s.getClass());}}
显然没有报错，返回的正是String类型。而不是spring配置的TestBean类型;

网上找到的小技巧：
String s= cont.getBean("&factorybean1",String.class);
bean的id前加个&得到的就是TestBean
