这个是applicationContext.xml的配置文件，如何做到修改b002中b001这个属性。
view plaincopy to clipboardprint
增加一个FactoryBean的自定义类。
view plaincopy to clipboardprint
java代码：如下：
view plaincopy to clipboardprint 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;
}
}
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;
