添加CGLib类包
public interface MaficBoss{
Car getCar();
}
<bean id="car" class="com.smart.injectfun.Car"
p:brand="宝马5x" p:price="2000000" ccope="prototype"/>
</bean>
<bean id="magucBoss" class="com.smart.injectfun.MagucBoss">
<lookup-method name="getCar" bean="car"/>
</bean>
通过lookup-method 元素标签为MagicBoss的getCar()提供动态实现,返回prototype类型的car Bean,这样spring将在运行期为MagicBoss接口提供动态实现,其效果等同于:
Public class MagucBossImpl implements MagicBoss, ApplicationContextAware{
private ApplicationContext ctx;
public Car getCar(){
return (Car) ctx.getBean("car");
}
public void setApplicationContext(ApplicationContext ctx) throws BeansException{
this.ctx = ctx;
}
}
