- 使用AbstractApplicationContext的程序包
  程序包 | 说明
  --- | ---
  org.springframework.context.annotation | Annotation support for the Application Context, including JSR-250 "common" annotations, component-scanning, and Java-based metadata for creating Spring-managed objects.
  org.springframework.context.support | Classes supporting the org.springframework.context package, such as abstract base classes for ApplicationContext implementations and a MessageSource implementation.

    `class` | `AnnotationConfigApplicationContext` Standalone application context, accepting annotated classes as input - in particular `@Configuration`-annotated classes, but also plain `@Component` types and JSR-330 compliant classes using `javax.inject` annotations.

    `class` | `AbstractRefreshableApplicationContext` Base class for `ApplicationContext` implementations which are supposed to support multiple calls to `refresh()`, creating a new internal bean factory instance every time.
    `class` | `AbstractRefreshableConfigApplicationContext` `AbstractRefreshableApplicationContext` subclass that adds common handling of specified config locations.
    `class` | `AbstractXmlApplicationContext` Convenient base class for `ApplicationContext` implementations, drawing configuration from XML documents containing bean definitions understood by an `XmlBeanDefinitionReader`.
    `class` | `ClassPathXmlApplicationContext` Standalone XML application context, taking the context definition files from the class path, interpreting plain paths as class path resource names that include the package path (e.g.
    `class` | `FileSystemXmlApplicationContext` Standalone XML application context, taking the context definition files from the file system or from URLs, interpreting plain paths as relative file system locations (e.g.
    `class` | `GenericApplicationContext` Generic ApplicationContext implementation that holds a single internal `DefaultListableBeanFactory` instance and does not assume a specific bean definition format.
    `class` | `GenericGroovyApplicationContext` An `ApplicationContext` implementation that extends `GenericApplicationContext` and implements `GroovyObject` such that beans can be retrieved with the dot de-reference syntax instead of using `getBean(java.lang.String)`.
    `class` | `GenericXmlApplicationContext` Convenient application context with built-in XML support.
    `class` | `StaticApplicationContext` `ApplicationContext` implementation which supports programmatic registration of beans and messages, rather than reading bean definitions from external configuration sources.
