WebApplicationContext (Spring Framework API 2.0) - Spring Framework 2.0.5 API 文档英文版

The Spring Framework

org.springframework.web.context
Interface WebApplicationContext

All Superinterfaces:
ApplicationContext, ApplicationEventPublisher, BeanFactory, HierarchicalBeanFactory, ListableBeanFactory, MessageSource, ResourceLoader, ResourcePatternResolver
All Known Subinterfaces:
ConfigurablePortletApplicationContext, ConfigurableWebApplicationContext
All Known Implementing Classes:
AbstractRefreshablePortletApplicationContext, AbstractRefreshableWebApplicationContext, GenericWebApplicationContext, StaticPortletApplicationContext, StaticWebApplicationContext, XmlPortletApplicationContext, XmlWebApplicationContext

public interface WebApplicationContext
extends ApplicationContext

Interface to provide configuration for a web application. This is read-only while the application is running, but may be reloaded if the implementation supports this.

This interface adds a getServletContext method to the generic ApplicationContext interface, and defines a well-known application attribute name that the root context must be bound to in the bootstrap process.

Like generic application contexts, web application contexts are hierarchical. There is a single root context per application, while each servlet in the application (including a dispatcher servlet in the MVC framework) has its own child context.

In addition to standard application context lifecycle capabilities, WebApplicationContext implementations need to detect ServletContextAware beans and invoke the setServletContext method accordingly.

Field Detail

ROOT_WEB_APPLICATION_CONTEXT_ATTRIBUTE

static final String ROOT_WEB_APPLICATION_CONTEXT_ATTRIBUTE
Context attribute to bind root WebApplicationContext to on successful startup.

Note: If the startup of the root context fails, this attribute can contain an exception or error as value. Use WebApplicationContextUtils for convenient lookup of the root WebApplicationContext.

WebApplicationContextUtils.getWebApplicationContext(javax.servlet.ServletContext), WebApplicationContextUtils.getRequiredWebApplicationContext(javax.servlet.ServletContext)

SCOPE_REQUEST

static final String SCOPE_REQUEST
Scope identifier for request scope: "request". Supported in addition to the standard scopes "singleton" and "prototype".

See Also:
Constant Field Values

SCOPE_SESSION

static final String SCOPE_SESSION
Scope identifier for session scope: "session". Supported in addition to the standard scopes "singleton" and "prototype".

See Also:

SCOPE_GLOBAL_SESSION

static final String SCOPE_GLOBAL_SESSION
Scope identifier for global session scope: "globalSession". Supported in addition to the standard scopes "singleton" and "prototype".
