本文整理了Java中org.springframework.context.ApplicationContext类的一些代码示例，展示了ApplicationContext类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。ApplicationContext类的具体详情如下：
包路径：org.springframework.context.ApplicationContext
类名称：ApplicationContext

ApplicationContext介绍

[英]Central interface to provide configuration for an application. This is read-only while the application is running, but may be reloaded if the implementation supports this.

An ApplicationContext provides:

  • Bean factory methods for accessing application components. Inherited from org.springframework.beans.factory.ListableBeanFactory.
  • The ability to load file resources in a generic fashion. Inherited from the org.springframework.core.io.ResourceLoader interface.
  • The ability to publish events to registered listeners. Inherited from the ApplicationEventPublisher interface.
  • The ability to resolve messages, supporting internationalization. Inherited from the MessageSource interface.
  • Inheritance from a parent context. Definitions in a descendant context will always take priority. This means, for example, that a single parent context can be used by an entire web application, while each servlet has its own child context that is independent of that of any other servlet.

In addition to standard org.springframework.beans.factory.BeanFactorylifecycle capabilities, ApplicationContext implementations detect and invoke ApplicationContextAware beans as well as ResourceLoaderAware, ApplicationEventPublisherAware and MessageSourceAware beans.
[中]为应用程序提供配置的中央接口。在应用程序运行时，这是只读的，但如果实现支持，则可能会重新加载。
ApplicationContext提供：
*用于访问应用程序组件的Bean工厂方法。继承自组织。springframework。豆。工厂ListableBeanFactory。
*以通用方式加载文件资源的能力。继承自组织。springframework。果心木卫一。ResourceLoader接口。
*将事件发布到已注册侦听器的功能。从ApplicationEventPublisher接口继承。
*能够解析消息，支持国际化。从MessageSource接口继承。
*从父上下文继承。子体上下文中的定义将始终优先。例如，这意味着整个web应用程序可以使用单个父上下文，而每个servlet都有自己的子上下文，独立于任何其他servlet的子上下文。
除了标准组织。springframework。豆。工厂BeanFactorylifecycle功能、ApplicationContext实现检测并调用ApplicationContextAware bean以及ResourceLoaderware、ApplicationEventPublisherAware和MessageSourceAware bean。
