Context and Dependency Injection (CDI) provides a common mechanism to inject component such as Enterprise JavaBeans (EJBs) or managed beans into other components such as JavaServer Pages (JSPs) or other EJBs.
Java CDI(Context and Dependency Injection) 一、Overview CDI提供的基本服务有: 1)Context:使用Context服务,让您能够把有状态组件的生命周期和交互绑定到一个定义良好并且可以扩展的生命周期环境中。 2)Dependency Injection:使用DI服务,让您能够把一个组件以类型安全的方式注入到一个应用中去,如果组件是个接口,那么...

Taking control meant managing the life cycle of the components, bringing dependency injection and configuration to your components. These services were built in to the container and programmers had to wait until later versions of Java EE to have access to them. Component configuration was made ...

A common cause of this error is disposing a context that was resolved from dependency injection and then later trying to use the same context instance elsewhere in your application. This may occur if you are calling Dispose() on the context, or wrapping the context in a using statement. If...
Spring框架的核心功能之一就是控制反转(Inversion of Control, IoC),也叫做依赖注入(dependency injection, DI)。关于依赖注入的具体内容可以参见Martin Fowler写的一篇文章《Inversion of Control Containers and the Dependency Injection pattern》。 Spring容器接口是BeanFactory,其提供了一些方法来配置和管理对象。Applicatio...
