This article is to share with you about the difference between FactoryBean and BeanFactory, the editor thinks it is very practical, so I share it with you to learn. I hope you can get something after reading this article.

FactoryBean and BeanFactory often ask in interviews what the difference is. BeanFactory We all know that the spring IOC core container stores a lot of information about bean. We usually get the getBean from this container. And FactoryBean is a special bean provided by the spring IOC container. This bean can be said to be the wrapper of a bean, which is both a bean and a bean.

The FactoryBean interface provides three methods, and getObject can return instance objects. In other words, we can put a self-instantiated object in this method, which is managed by the spring container with the help of FactoryBean. In fact, the spring container manages the bean of FactoryBean. The bottom layer of spring will determine whether the bean is FactoryBean when it is getBean, and if it is FactoryBean, call its getObject method.

Note: mybatis uses the FactoryBean interface to deliver its own mapper scan objects to the spring container for management.

These are the differences between FactoryBean and BeanFactory. The editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
