在AbstractBeanFactory的doGetBean方法：

调用的getObjectForBeanInstance方法部分代码如下：

如果不是工厂bean,则直接将实例返回，否则调用getObjectFromFactoryBean方法获取工厂bean的getObject方法返回的对象

	protected Object getObjectFromFactoryBean(FactoryBean<?> factory, String beanName, boolean shouldPostProcess) {if (factory.isSingleton() && containsSingleton(beanName)) {synchronized (getSingletonMutex()) {Object object = this.factoryBeanObjectCache.get(beanName);if (object == null) {object = doGetObjectFromFactoryBean(factory, beanName);// Only post-process and store if not put there already during getObject() call above// (e.g. because of circular reference processing triggered by custom getBean calls)Object alreadyThere = this.factoryBeanObjectCache.get(beanName);if (alreadyThere != null) {object = alreadyThere;}else {if (shouldPostProcess) {if (isSingletonCurrentlyInCreation(beanName)) {// Temporarily return non-post-processed object, not storing it yet..return object;}beforeSingletonCreation(beanName);try {object = postProcessObjectFromFactoryBean(object, beanName);}catch (Throwable ex) {throw new BeanCreationException(beanName,"Post-processing of FactoryBean's singleton object failed", ex);}finally {afterSingletonCreation(beanName);}}if (containsSingleton(beanName)) {this.factoryBeanObjectCache.put(beanName, object);}}}return object;}}else {Object object = doGetObjectFromFactoryBean(factory, beanName);if (shouldPostProcess) {try {object = postProcessObjectFromFactoryBean(object, beanName);}catch (Throwable ex) {throw new BeanCreationException(beanName, "Post-processing of FactoryBean's object failed", ex);}}return object;}}

其中调用了doGetObjectFromFactoryBean方法，代码如下：

可以看到工厂bean的getObject方法被调用
