spring bean是什么 -- 重学程序第一天
bean定义
Spring 官方文档对 bean 的解释是:
In Spring, the objects that form the backbone of your application and that are managed by the Spring IoC container are called beans. A bean is an object that is instantiated, assembled, and otherwise managed by a Spring IoC container.
翻译过来就是:
在 Spring 中,构成应用程序主干并由Spring IoC容器管理的对象称为bean。bean是一个由Spring IoC容器实例化、组装和管理的对象。
