org.springframework.web.context.support (Spring Framework 5.2.12.RELEASE API)

Classes supporting the org.springframework.web.context package, such as WebApplicationContext implementations and various utility classes.

类概要
类	说明
AbstractRefreshableWebApplicationContext	`AbstractRefreshableApplicationContext` subclass which implements the `ConfigurableWebApplicationContext` interface for web environments.
AnnotationConfigWebApplicationContext	`WebApplicationContext` implementation which accepts component classes as input — in particular `@Configuration`-annotated classes, but also plain `@Component` classes and JSR-330 compliant classes using `javax.inject` annotations.
ContextExposingHttpServletRequest	HttpServletRequest decorator that makes all Spring beans in a given WebApplicationContext accessible as request attributes, through lazy checking once an attribute gets accessed.
GenericWebApplicationContext	Subclass of `GenericApplicationContext`, suitable for web environments.
GroovyWebApplicationContext	`WebApplicationContext` implementation which takes its configuration from Groovy bean definition scripts and/or XML files, as understood by a `GroovyBeanDefinitionReader`.
HttpRequestHandlerServlet	Simple HttpServlet that delegates to an `HttpRequestHandler` bean defined in Spring's root web application context.
LiveBeansViewServlet	Servlet variant of `LiveBeansView`'s MBean exposure.
RequestHandledEvent	Event raised when a request is handled within an ApplicationContext.
ServletConfigPropertySource	`PropertySource` that reads init parameters from a `ServletConfig` object.
ServletContextAttributeExporter	Exporter that takes Spring-defined objects and exposes them as ServletContext attributes.
ServletContextAttributeFactoryBean	`FactoryBean` that fetches a specific, existing ServletContext attribute.
ServletContextAwareProcessor	`BeanPostProcessor` implementation that passes the ServletContext to beans that implement the `ServletContextAware` interface.
ServletContextLiveBeansView	`LiveBeansView` subclass which looks for all ApplicationContexts in the web application, as exposed in ServletContext attributes.
ServletContextParameterFactoryBean	`FactoryBean` that retrieves a specific ServletContext init parameter (that is, a "context-param" defined in `web.xml`).
ServletContextPropertySource	`PropertySource` that reads init parameters from a `ServletContext` object.
ServletContextResource	`Resource` implementation for `ServletContext` resources, interpreting relative paths within the web application root directory.
ServletContextResourceLoader	ResourceLoader implementation that resolves paths as ServletContext resources, for use outside a WebApplicationContext (for example, in an HttpServletBean or GenericFilterBean subclass).
ServletContextResourcePatternResolver	ServletContext-aware subclass of `PathMatchingResourcePatternResolver`, able to find matching resources below the web application root directory via `ServletContext.getResourcePaths(java.lang.String)`.
ServletContextScope	`Scope` wrapper for a ServletContext, i.e. for global web application attributes.
ServletRequestHandledEvent	Servlet-specific subclass of RequestHandledEvent, adding servlet-specific context information.
SpringBeanAutowiringSupport	Convenient base class for self-autowiring classes that gets constructed within a Spring-based web application.
StandardServletEnvironment	`Environment` implementation to be used by `Servlet`-based web applications.
StaticWebApplicationContext	Static `WebApplicationContext` implementation for testing.
WebApplicationContextUtils	Convenience methods for retrieving the root `WebApplicationContext` for a given `ServletContext`.
WebApplicationObjectSupport	Convenient superclass for application objects running in a `WebApplicationContext`.
XmlWebApplicationContext	`WebApplicationContext` implementation which takes its configuration from XML documents, understood by an `XmlBeanDefinitionReader`.
