A bean is an object that is instantiated, assembled, and otherwise managed by a Spring IoC container. Otherwise, a bean is simply one of many objects in your application. Beans, and the dependencies among them, are reflected in the configuration metadata used by a container. 配置和使用 配置...
什么是 Spring inner beans？在 Spring 框架中，无论何时 bean 被使用时，当仅被调用了一个属性。一个明智的做法是将这个 bean 声明为内部 bean。内部 bean 可以用 setter 注入 属性 和构造方法注入 构造参数 的方式来实现。比如，在我们的应用程序中，一个 Customer 类引用了一个 Person 类，我们的要做的是...

对象引用循环依赖在某些业务场景上可能是合理存在的,但是由于SpringContainer设计了依赖注入机制,即SpringContainer在创建bean实例化以后需要给bean中的属性自动赋值,之后要全部自动赋值如果出现循环依赖的情况,以两个bean相互依赖的情况为例,假设有AService已经实例化(但未完成初始化),但是AService中需要自动分配的BService并...
* Spring的出发点是用声明性事务代替EJB,因此Spring和Jakarta EE是竞争关系。 * Spring是第三方框架,Jakarta EE是规范,Spring的所有开发必须满足Jakarta EE平台的要求。 * Spring用声明性事务替代EJB后,两者又成为互补关系。 Rod Johson说:While some consider Java EE and Spring to be in competition, Spring is...
