spring中基于BeanFactoryAware动态替换指定的bean

这个是applicationContext.xml的配置文件，如何做到修改b002中b001这个属性。

增加一个FactoryBean的自定义类。

<bean name="b001FactoryBean" name="code">package com.alibaba.zj.spring.factorybean;import org.springframework.beans.BeansException;import org.springframework.beans.factory.BeanFactory;import org.springframework.beans.factory.BeanFactoryAware;import org.springframework.beans.factory.FactoryBean;import org.springframework.beans.factory.InitializingBean;import com.alibaba.zj.spring.bean.B001;import com.alibaba.zj.spring.bean.B002;public class B001FactoryBean implements FactoryBean ,InitializingBean,BeanFactoryAware {    private BeanFactory beanFactory;    private B001 b001;    @Override    public Object getObject() throws Exception {        return b001;     }    @Override    public Class getObjectType() {        return B001.class;    }    @Override    public boolean isSingleton() {        return true;    }        public B001 getB001() {        return b001;    }    @Override    public void afterPropertiesSet() throws Exception {       this.b001 = new B001();       this.b001.setName("FactoryBean Created me");    }    @Override    public void setBeanFactory(BeanFactory beanFactory) throws BeansException {        this.beanFactory = beanFactory;    }        public BeanFactory getBeanFactory() {        return beanFactory;    }        }
